Shrink Your Disposal Costs with a PreCrusher. Get 30% greater compaction results than with a standard compactor! A PreCrusher eliminates “light loads” of pallets, crates, large boxes, and drums that fill your container with air. The packing ram moves through the charge box with a high level of force that effectively crushes everything against the PreCrusher’s vertical steel wall. The wall is then raised and the ram fully extends, compacting the refuse into the attached container. Uniform compaction is achieved throughout the receiver container. Every stroke is a crushing compaction stroke. The results: fewer trips to the landfill!
