Dumpers are used to raise and load the compactor hopper with the waste which has been gathered in compatible carts. Dumpers are recommended for customers that generate a lot of trash from different collection areas or generate heavy by-products. Examples of these are hospitals, RV parks, manufacturing plants and apartment complexes.

Dumpers are capable of being installed next to a compactor at ground level as well as off loading docks. Both stationary and self-contained compactors can utilize the benefits of a dumper. Dumpers, however, are made specifically to fit different sizes of carts. Carts vary in size from 90 gallons to as large as 4-cubic yards.
