Before the excavated material had to be changed or screened using a stationary screener which required two people and two excavators.
Now with ALLU screening bucket attached to the excavator the work is done very effectively with one driver and one base machine. Also there is no idle time for the excavators.
At this site, remarkable time and money savings were achieved.
