Harsco Metals and ALLU – A Partnership for Operational Excellence

Harsco Environmental is a global leader in providing sustainable solutions for the steel and metals industries. At its Laverton branch in Melbourne, Australia, the team specializes in slag processing, repurposing industrial byproducts into valuable products like aggregates for the road and civil industries. However, recurring operational challenges threatened efficiency and productivity, prompting the need for an innovative solution.

The Challenge: Conveyor Belt Tearing

At Harsco’s Laverton branch, the conveyor belts were frequently damaged during slag processing. The issue arose from the fact that the slag collected from the caster pit contained metal rebars and other oversized contaminants that were not effectively screened out using the existing equipment. These materials were not properly filtered using a skeletal bucket, leading to sharp items damaging the downstream conveyor belts during transfer to the crushing line. This caused increased downtime due to frequent maintenance, high operational costs from repairs and inefficiencies, as well as safety risks and disruptions in the overall slag processing operations.

Impact:

  • Increased downtime due to frequent maintenance.
  • High operational costs from repairs and inefficiencies.
  • Safety risks and disruptions in slag processing.

The Solution: ALLU Transformer Bucket

Recognizing the need for a more efficient and robust screening solution, Harsco Metals’ maintenance team contacted Walkers Hammers, the ALLU dealer in Melbourne, Victoria.

  • Site Study and Demo:
    On 12th April 2024, Sami Rahman, ALLU area sales manager conducted a site study and recommended the ALLU DN 2-12  Transformer bucket with specialized X75 drums. Carlo Costanzo, Walkers Hammers’ service technician, prepared the equipment by fitting a head bracket for a CAT excavator.
  • Key Stakeholders at the Demo:
    The demo was attended by General Manager Andrew Hayes, site supervisor Nazz, and Dan from the maintenance team. The ALLU bucket demonstrated its ability to screen slag efficiently, removing metal rebars and oversized contaminants while protecting downstream equipment.
  • Extended Testing:
    Impressed by the demo, Harsco Metals rented the ALLU DN 2-12 bucket for two weeks to test it with their operators across multiple shifts. This ensured operator familiarity and confidence in the equipment’s performance.

The Result: Quick Decision and Seamless Delivery

At the conclusion of the rental period, Walkers Hammers presented a sales offer tailored to Harsco’s needs.

COST EFFECTIVE CRUSHING
ALLU screening buckets transform contract crushing & screening business

When Leicestershire-based MRD Plant, which provides nationwide services to the UK recycling, construction, quarrying & mining sectors, first invested in a second-hand ALLU screening bucket just over a year ago, they quickly realised the benefits of this innovative Finnish-manufactured hydraulic attachment. Since then, they have added three new models to their machinery fleet, all supplied by dealers Blue Group.

“The ALLU screening bucket is so much more efficient, productive and less expensive than bringing a mobile crushing plant on to the work site…”

They were initially attracted to the ALLU DS 3-23 screening bucket after securing a series of relatively small crushing and screening contracts, as it was more cost-effective for their clients than employing an expensive mobile crusher on the job site. Earlier this year, they took delivery of a brand-new ALLU DH 4-17 model, primarily to process asphalt road planings that would otherwise end up in a landfill.

MRD Plant’s Managing Director, Tom Chapman, has nothing but praise for the ALLU transformer buckets, which can screen, crush, pulverize, mix, and separate a wide range of materials. If the material is particularly wet or dirty, they are far more efficient at processing it than a standard mobile screener.

Using the machine’s hydraulic system, the ALLU screening buckets—virtually converting your excavator or loading shovel into a mobile processing plant—are user-friendly and allow for quick attachment, ensuring easy control and operation. With interchangeable blades and spacings of various sizes, you can easily adjust the particle size to meet the different requirements of job sites.

“In many cases, an ALLU screening bucket is much more efficient, productive, and less expensive than transporting a mobile crushing plant to the work site. That’s something we began to realize when we invested in that second-hand model last year. Some of the contracts we secure now involve processing just a few hundred tonnes of material over a couple of days, and it would have been inefficient to set up a standard mobile crusher on-site.

Had we done that, we would still have to use a loading shovel to feed the crusher. The fact that we can fit an ALLU screening bucket to the shovel means we are literally halving our fuel costs and using less labour on-site,” said Tom. “As a result, we can pass those cost savings on to our clients, which they appreciate.”

The ALLU DH 4-17 screening bucket, one of the largest in the D-Series range, is specifically used by MRD Plant to process road planings. However, it can also screen and separate various other materials, including different soil types, sand, gravel, topsoil, compost, demolition waste, biomass, processing, and products of different fractions. This makes the D-Series suitable for various applications, including construction, excavation, recycling, landscaping, and agriculture.

DOING MORE FOR LESS


More or less permanently fitted to a 35-tonne Hitachi Zaxis 350-7 excavator, the ALLU DH 4-17 screening bucket is in constant use.

“It essentially does the same job for less than a top-of-the-range mobile crusher,”

added Tom, who established MRD Plant in 2022 after working alongside his father in a similar business before it was sold in 2019.

Tom Chapman, Managing Director, MRD Plant

“Apart from the versatility of the ALLU screening buckets, I was also attracted to them because of their simplicity. They are easy to use and much easier to maintain compared to a standard mobile crusher. Plus, being fitted to an excavator or loading shovel, they enable us to access restricted sites where we might not be able to bring in a separate crusher unit.”

The other three ALLU buckets in the MRD Plant crushing and screening division are fitted to two JCB loading shovels and a smaller Hitachi excavator. They are easily interchangeable to suit various applications. One of the ALLU transformer buckets has been used to break up and screen Pulverised Fuel Ash (PFA), also known as fly ash, which can then be partly used as a cement substitute in the manufacture of concrete blocks. Extremely wet PFA would be impossible to screen using a conventional mobile screener, and this material would normally end up going to landfill.

In just a few short years, Tom Chapman has built MRD Plant into a successful and growing contract crushing and screening operation that can take on projects ranging from small-scale work to larger, long-term contracts. In addition to the ALLU buckets, he currently operates two mobile crushers, three excavators, and five loading shovels.

PLANT HIRE DIVISION


The business also includes a plant hire division with an expanding fleet of excavators, loading shovels, mobile jaw crushers, and screeners, all available on either an operator or self-drive rental basis.

The plant hire division also offers a variety of ALLU transformer buckets, which are not only limited to aggregate processing but can also be used to meet the requirements of almost any application—from pipeline filling and compact soil processing to highway construction and asphalt recycling. These buckets serve a range of sectors, including quarrying and mining, and wood chip & biomass production.

Since starting the company, Tom has enjoyed a highly successful working relationship with both Blue Group and ALLU.

“They have been very supportive and have put in a lot of effort to ensure we have screening buckets that work for us, especially with the DH 4-17, which we primarily use for processing asphalt. Any issues or queries we have are dealt with promptly and efficiently, and we look forward to building on that relationship going forward.”

BonnyView and  ALLU the perfect partners

When mine and quarrying veteran Len Hardy decided he needed two “big” new buckets for his of Bonnyview Quarries business in NSW, he knew exactly what brand he wanted and where to turn to when he wanted to buy them.

Having used a number of smaller ALLU buckets on his excavators over the years, Len had his eyes on a pair of ALLU DH4-23 XHD25 screening buckets to take on the bigger jobs and provide additional versatility to his operation, which supplies customers right across NSW.

Built by Finnish private limited company ALLU Finland Oy, the ALLU screen crushers are highly versatile and the ideal tool for creating material such as road base and building materials.

According to Len, they are the perfect fit for his business.

“They are the best constructed buckets for the applications we use them for. They are really well engineered and provide a very reliable performance,” he said.

“The two new buckets we acquired are performing really well and we couldn’t be happier.”

Len is just as high in his praise for local ALLU support distributors in Australia, with whom he has had a lengthy relationship.

“RDW group are a very, very, good company to deal with. They are great suppliers and will always come up with what you want,” he recently told Australian Mining Review.

RDW group has been the Australian importer and distributor for ALLU for around four years. distributing the product through a nation wide network, servicing major infrastructure projects including water and gas , however, the versatile ALLU system is quickly making inroads with civil and composting contractors.

Sales Area Manager in Rockbreakers Queensland, Craig Einam, said ALLU bucket applications and  installations continue to grow and develop each year.

The versatility  of the buckets to be fitted to 5T – 80T excavators and larger style loaders makes them particular popular with quarry operators like Len, while the smaller buckets are also effective on skid steer loaders.

Why Add Water When It Isn’t Necessary? A Practical Solution for Soil Stabilization in Nordic Roadworks

In the realm of construction, challenges posed by soft or unstable soils can be daunting. However, innovative techniques such as Nordic Dry Deep Soil Mixing (NDDM) offer reliable solutions without unnecessary complexity. This method demonstrates its value by improving soil stability and strength without the excessive use of water—an approach both efficient and environmentally considerate.

Project Overview: Foundation Preparation with Precision

A recent roadworks foundation project in the Nordic region highlighted the practical application of NDDM. The project scope included the construction of 12,000 soil-stabilizing columns, each reaching a depth of 10 meters (32 feet) with a diameter of 600 mm, collectively spanning an impressive total length of approximately 120 kilometers (74 miles).

Using a lime-cement mix as the binder, 40 kilograms (88 pounds) were applied per meter of each column. The outcome was a durable foundation capable of withstanding demanding load-bearing conditions.

Equipment in Action: Reliable Tools for Reliable Results

The success of the project hinged on the integration of robust equipment:

  • ALLU PF 7+7 NextGen 10 Bar Pressure Feeder: Ensuring consistent and precise delivery of dry binders deep into the ground.
  • MOVAX MSL-300 Column Stabilisation Leader: An excavator-mounted tool designed for the efficient creation of stabilization columns.

This combination provided seamless operation, even in the most demanding soil conditions, ensuring the job was completed with precision and reliability.

Explore how the Nordic Dry Deep Mixing method enhances soil stability without water, featuring ALLU's PF 7+7 NextGen feeder for precise and efficient foundation construction.

Why Choose Dry Over Wet Stabilization?

Nordic Dry Deep Mixing sets itself apart from traditional methods by omitting the need for added water, a factor that significantly simplifies the process. Some notable advantages include:

  1. Environmental Considerations
    By reducing water usage, NDDM minimizes the risk of runoff and contamination, particularly in regions with high groundwater levels. This makes it a preferred choice for environmentally sensitive areas.
  2. Enhanced Precision
    Dry binders allow for controlled application, ensuring uniform strength and stability, even in soils with varying properties like clay or peat.
  3. Faster Results
    Dry binders typically achieve the desired strength more quickly than their wet counterparts, shortening project timelines and reducing waiting periods for curing.
  4. Suitability for Difficult Conditions
    In saturated or clay-rich soils, where water-based methods may fail due to dilution, NDDM excels by providing consistent results.
  5. Reduced Complexity
    With no added water, there’s no need for managing slurry or dealing with excess waste, streamlining logistics and cutting down on ancillary costs.

A Method Rooted in Practicality

The Nordic Dry Deep Mixing method isn’t just about achieving technical excellence; it’s about approaching projects with care and foresight. By avoiding the unnecessary addition of water, this method prioritizes efficiency and environmental responsibility.

For the foundation project in question, the combination of NDDM and ALLU’s PF 7+7 NextGen feeder exemplified how precision equipment and proven methods can align to create lasting infrastructure. The resulting columns are a testament to how carefully planned construction can address even the most challenging soil conditions.

ALLU PF Pressure Feeder

The double tank ALLU Pressure Feeder PF 7+7 NextGen allows for continuous feeding and precise dosing of dry binders in soil improvement projects.

Soil Recycling Co. is at the forefront of soil screening in Australia, dedicated to promoting the reuse of soil as a valuable resource rather than disposing of it in landfills. This innovative company specializes in soil handling and recycling, collaborating with major waste management firms like ResourceCo to transform organic waste into usable products such as soil mixes for gardening and landscaping. Currently, Soil Recycling Co. is working at the South Gippsland Highway, Hampton Park in Victoria.

Founded in 2012, Soil Recycling Co. emerged from a passion for soil and organics, recognizing the inefficiencies in how materials were handled. The company saw countless trucks transporting soil and organic materials, only for them to return to the site soon after. This inefficiency sparked the mission to make onsite resources usable, eliminating unnecessary transport and fostering sustainable practices in the industry.

Chris Keay, the Director of Soil Recycling Co.

When Chris Keay, the Director of Soil Recycling Co., faced the challenge of processing wet, clumped soil that affected the performance of the Terex Ecotec Trommel, he recognized the necessity for a more effective solution. Two main issues arose due to the damp and wet soil:

  • Less aerated soil resulted in clumps clogging the hopper and Trommel.
  • The operator, Craig Jameson, had to clean the trommel multiple times a day, leading to significant downtime and fatigue, thus affecting productivity.

Initial attempts with another type of screening bucket featuring outdated drum technology failed to break down the lumps and dense soil, resulting in clogging and drastically reduced production. In search of a more reliable option, Chris Keay reached out to Walkers Hammers on September 16th, 2024, and discovered the innovative screening solutions from ALLU.

After reaching out to Walkers Hammers, Chris was introduced to Sami Rahman, the ALLU area sales manager based in Melbourne, Victoria. Together, they identified the ALLU DN 2-12 with TS 25 Axe as the optimal bucket for the demo. Sami, along with Carlo Costanzo from Walkers Hammers, prepared the rental bucket for a demonstration scheduled for September 17th. Upon arriving at the site, it became clear why the Trommel Screener had been struggling; persistent rain had saturated the soil, complicating the processing.

Once installed on the Hidromek excavator, the ALLU bucket quickly demonstrated its capabilities. The unique TS drum setup, designed for anti-clogging, optimal flow and self-cleaning, allowed for effective processing, leading to significant improvements in output. Impressed by its performance, Chris decided to keep the rental bucket for ongoing use, ensuring he had the right equipment to tackle his challenges effectively.

To further enhance productivity, the decision was made to switch from TS 25 to TS 50 blades, allowing for better fragmentation of larger soil lumps. Carlo from Walkers Hammers took the bucket back for the blade change, although it could have been done onsite. The bucket was delivered the next day with the blades changed to TS 50, ready for action.

Operational Highlights:

September 18: ALLU bucket installed in the morning; processed 310 m³ of topsoil for the remainder of the day (measured from the monitoring system installed on the Terex Ecotec Trommel).

September 19: Next full day of operation with the ALLU bucket, processing 280 m³ of topsoil due to the poor weather with heavy rain.

September 20: To be able to compare the customer decided to use the GP bucket the full day which resulted in approximate 20% lower efficiency than the ALLU bucket, and required frequent cleaning due to clogging issues.

The following are production figures with ALLU and GP bucket after the demo/test:

In addition to enhancing productivity, the ALLU Variable Drum allows customers to bid on smaller jobs, reducing reliance on larger trommels. Immediately, the productivity of the Terex Trommel increased by 10-20% with the smaller ALLU rental bucket, and with the new purchased DN 3-12 TS VD further great efficiency is anticipated. This capability not only streamlines operations but also promises a quick return on investment, making it an attractive option for contractors looking to optimize their resources.

This collaboration highlights the strong partnership between ALLU and Walkers Hammers, reflecting our commitment to delivering efficient solutions. Together with Walkers Hammers and our valued customer, Soil Recycling Co., we are dedicated to providing sustainable solutions and efficient waste management.

A Central Victorian contractor and ALLU buckets are giving nature a helping hand to create healthier soils.

A Central Victorian contractor and ALLU buckets are giving nature a helping hand to create healthier soils.

To the right is a ramshackle pile of, well let’s be blunt, manure. Straight from the farm, it’s mixed with straw, dirt, and all manner of contaminants. And a little unpleasant on the nose.

Just a few meters away is a mound of compost. A dark earthy brown in color, it’s rich and moist to the touch and smells natural. It’s difficult to believe that both piles looked the same just weeks ago. Even a seasoned farmer such as Gino is impressed by the result.

“It looks a picture,” Gino says. “The quality of the product is amazing once you send it through that bucket.”

That bucket is an ALLU Transformer DN 2-12 Screening Bucket which, for the past two years, has lived up to its name and transformed Gino’s compost. Through his Natural Compost Co. in central Victoria, Gino is cultivating a move away from synthetic farming and giving nature’s processes a helping hand, working with farmers to convert manure to compost on-site.

Working on-farm means there are contaminants in the compost piles—stones, string, and steel are the usual culprits. Early attempts to run the piles through a hired trommel proved expensive and often difficult to organize.

Gino even bought a shaker bucket—“a big bucket with holes in it”—but it wasn’t up to the job. (He’s since put a metal plate in the bottom of it and is using it as a digger.)

A bit of research led him to ALLU buckets and, as the saying goes, the rest is history.

“Sami Rahman, Area Sales Manager for ALLU, called me the next day to talk about the problems I was having and what he thought could do the job,” Gino says. “He got the measurements of what machine I was using, organized a trial on-site, and soon after had two buckets on a trailer to Newbridge.”

Gino spent that afternoon “playing” with the recommended buckets. He says he was so impressed; Sami and Carlo Costanzo, a service technician with Walkers Hammers who commissioned the demonstration buckets, went home that day with just one bucket—Gino was going to rent the other.

The next day, he ordered a new bucket with TS 16 Axe blades, enabling a homogenous end product.

“The compost fell out of the bottom of the machine like rain,” Gino says. “It looks like a picture, all nicely processed and sifted. Any contamination and oversize items – we’ve got it set to 40 mm – are left sitting in the bucket.”

“It’s magnificent.”

It’s designed to screen and separate various materials including soil, sand, gravel, compost, and demolition waste on-site, reducing the need for extra equipment and transport costs while minimizing environmental impact.

Carlo provided support with the installation of the new bucket and operator training, a service Walkers Hammers offers to all Victorian businesses that purchase ALLU products.

Gino uses the bucket on two excavators. To make switching the bucket between the machines easy, ALLU built a head bracket to cater for the two different pin sizes and spaces. He says it makes what is already a productive machine even more so.

Last year, Gino was contracted to process about 5,000 tonnes of compost for farmers. He’s currently working with a wastewater facility to convert sludge removed from a dam several years ago into compost that can be used on-site. He says since buying the Transformer bucket in 2021, his clients are also noticing the difference in the quality of compost produced.

He cites a local farmer who in 2022 had three rows of compost on his farm, one of which was processed through the ALLU bucket. When Gino returned recently to consolidate the rows, the farmer singled out the ALLU-processed row.

“The other two rows, they were good,” Gino says. “But that row that was sifted was like sand. From a quality perspective, running it through that bucket made a difference. Nature will get it there, but the bucket helps me get it there quicker.”

Function Break down large limestone boulders

Model M 3-25 X75

Crushing large volumes of limestone effectively calls for equipment that guarantees speed and accuracy. In the demanding environment of Oman, a customer chose the ALLU M 3-25 screening bucket, mounted on a Hitachi 90-tonne excavator, to handle limestone boulders with precision and speed. This solution not only eliminated the need for a conventional crusher but also transformed operations into a one-step process that saved time, reduced costs, and minimized environmental impact.

The Challenge: Crushing Limestone Boulders for Road Construction

The customer’s challenge was to break down large limestone boulders ranging from 0 to 300 mm into smaller, manageable pieces, specifically between 0 and 90 mm. The material needed to be prepared as sub-base for the internal road construction at the Royal Oman Police Headquarters. Conventionally, this would require multiple machines and permits to set up a traditional crusher on-site, causing additional costs and logistical complexities.

The ALLU Solution: One-Step Operation with M 3-25 Screening Bucket

Choosing the ALLU M 3-25 X75 over a traditional crusher setup, the customer valued its capacity to condense several stages of the process into one seamless operation. Mounted on a Hitachi 90-tonne excavator, the ALLU screening bucket ensured a smooth, efficient workflow throughout the operation. The excavator simply picked up the boulders, crushed them to the desired size, and loaded them directly onto trucks for transport.

This one-step operation not only saved the customer significant time and reduced the need for additional equipment but also minimized environmental impact by reducing fuel consumption and the overall number of machines on-site. The crushed material was perfectly sized for the sub-base application, helping ensure that the project was completed efficiently and on time.

Key Benefits of the ALLU Screening Bucket:

  1. Cost-Efficient Versatility: By choosing this screening bucket, the customer bypassed the permits and costs of a conventional crusher, while handling a large-scale operation with one versatile attachment.
  2. One-Step Process: The ALLU screening bucket streamlined the operation into a single process, from picking up material to crushing and loading it onto trucks.
  3. Sustainable Precision: Fewer machines on-site meant reduced emissions and fuel consumption, while the bucket’s precision ensured perfectly sized material for sub-base road construction.

Why ALLU Stands Out for Material Processing

ALLU’s innovative screening and crushing buckets, like the M 3-25, are engineered for large-scale operations in industries such as construction and mining. Designed for efficiency, they reduce the need for multiple machines while boosting productivity and streamlining job site processes. Whether you’re crushing limestone, screening soil, or preparing materials for road construction, ALLU delivers reliable, durable equipment that can handle even the toughest materials, transforming how you approach material handling.

Model ALLU DH3-23 TS35

Problem

ALLU Bucket Delivers Efficient Quarry Waste Handling in China In the world of quarrying, managing waste efficiently is more than a necessity—it's a responsibility. Quarry owners often face the challenge of dealing with a mix of stone and clay, leftover materials that don’t seem valuable at first glance. But what if those materials could be turned into something profitable and even environmentally friendly? This is where the ALLU DH3-23 TS35 screening bucket makes a difference. Working alongside the CAT 336 excavator, this combination does more than just handle waste—it transforms it. Quarry owners found themselves searching for a solution that would allow them to handle waste effectively while still being cost-efficient. ALLU delivered just that.

Solution

From Waste to Resource in 3 Steps Handling leftover tailings and waste during quarry operations can be challenging. Often a mix of stone and clay, these byproducts are typically hard to sell or repurpose. But using the ALLU Transformer DH3-23 TS35, this waste gets a new life. The process follows three simple steps: 1. Raw Material Collection: Quarry waste, often seen as byproducts, is collected for screening. 2. Screening and Separation: ALLU's bucket separates larger stones (over 3 cm) from finer material (below 3 cm). The large stones are ready for direct sale to stone processing plants. 3. Resource Utilization: The finer material, perfect for road construction and landscaping, is repurposed, turning waste into valuable resources. The ALLU screening bucket separates materials by size, repurposing both large and fine particles. Larger stones are sent to processing plants for resale, while finer materials are used in road construction or landscaping. This process boosts the market value of the stone and provides additional economic benefits to quarry owners.

Benefit

Dual Benefits for Profit and Sustainability ALLU Transformer offers quarry owners an efficient, one-step screening service. By separating larger stones for resale and finer materials for road construction, this process maximizes resource use and brings financial returns. The recovered stones often hold more market value than raw materials, while the finer products serve environmental remediation purposes like land restoration. This solution reduces waste accumulation and promotes recycling, helping quarry owners balance profitability and environmental responsibility. It’s a win-win scenario: fewer waste piles, more revenue, and a positive environmental impact. Conclusion: Balancing Profit and Responsibility ALLU has proven that in today’s quarrying industry, efficiency, sustainability, and profitability don’t have to be at odds. By reducing waste accumulation and promoting resource reuse, ALLU helps quarries strike the perfect balance between economic growth and environmental responsibility. With the DH3-23 TS35 in hand, quarry owners can meet regulatory requirements, generate additional revenue streams, and contribute to a cleaner, greener future. It's not just about screening—it’s about turning challenges into opportunities. And that’s the power of ALLU.

Problem

Ware Excavator Inc in USA recognised that Topsoil is in demand in the area, yet there are limited suppliers. ALLU Transforms the raw material

Solution

ALLU Group Inc based in NJ works through a dealer network. CAT Stowers is our local ALLU dealer and they offered us the perfect solution. We brought a wheel loader to do pipework’s, but then added the ALLU Transformer. Initially I wasn’t sure on how long this would take to pay back for the ALLU, but within 6 months it has transformed our business model!

Benefit

Our main business was in commercial and residential developments. The wheel loader we brought from CAT Stowers was to do pipework’s. Since we added the ALLU for screening the soil, the CAT wheel loader only left the yard once! It no longer leaves the yard; it remains on site to screen the dirt which is much more effective and profitable. On average we do 10 loads a day making $600 per load. It’s much more profitable. Our original business model haling for a customer’s we were lucky to make $50 per load, by the time we had paid the taxes, and costs. ALLU Transformer has given us a stable other income and is becoming our prime focus. Local landscapers, building contractors, City of Cleveland, Cleveland utilities, now come and take the raw material we made with the ALLU and it makes it look nice and need and new for their projects. I’m so happy that we have also invested in a 5-17FD Crusher and now do Asphalt and concrete recycling too. ALLU has transformed my business, cutting down our transport costs, operating costs and increasing our profits by far! I’m happy with the ALLU Transformer, its reliable, efficient solution which has increased our productivity and business profits. We have now bought some more land to expand our business using the ALLU. WARE EXCAVATOR WITH CAT STOWERS AND ALLU
