The goal of pushing is simple: Move as much as possible without spinning the tires or losing material around the edges. Here’s a technique the best operators use: Engage the pile with a flat bucket on the ground. Make contact, then raise the bucket one-half to one inch to clear the floor and slide the load. This method helps prevent friction and wheel spin and lowers fuel burn.
Stockpiling is trickier. Sometimes the building configuration or capacity doesn’t allow for adequate storage, requiring operators to stack material as high as possible. In that case, one best practice is to leave a load or two at the foot of the pile, then push it up with the next load — sliding material higher on to the stockpile. Another option is for the operator to raise the lift arms as high as the machine will allow and, while dumping the load, make a slight indention in the waste with the bucket. He can then push the next load into that space.
When it comes to sorting, the key is having the right tool on the end of the machine. Sorting grapples and grapple buckets work best for quickly grabbing, pulling, carrying and rejecting unwanted material.
Loading best practices are more complicated and vary based on the type of load-out for which your building is designed.
To achieve fully rated loads, many transfer station and MRF operators tamp material. Should they? To find out, compare a few tamped and un-tamped loads. You may discover the slight amount of weight you gain isn’t worth the extra time, increased fuel burn and added stress on equipment. If you do find that tamping has value, train your operators to follow these best practices:
Putting a few (if not all) of these best practices into action will go a long way toward helping you raise production and efficiency — and lower maintenance, fuel and floor costs — at your transfer facility or MRF.
