The Heavy-Duty Low-Profile 90° Self-Dumping Steel Hopper features a full 90 degree dump angle with a cushioned rubber stop bumper. The low-profile design is essential for convenient loading, and dumping with a forklift is quick and simple. Pull the included manual pull-cable from the seat of the forklift to dump the hopper. The unit returns to an upright and locked position when lowered to the ground. The included safety restraint should be properly secured to a forklift before dumping.
