Roll-offs are placed by roll-off trucks. As the roll-off truck raises its hydraulically operated bed, the roll-off container rolls off the bed. A cable is used to slowly lower the container. After the waste container is loaded, the roll-off truck pulls the filled container onto the roll-off truck with the cable and winch system.
The truck goes to the dumpsite, after it has been dumped the empty container is taken and placed to be loaded or stored. The hoist is raised and the container slides down the subframe so the rear is on the ground. The container has rollers on the rear and can be moved forward or back until the front of it is lowered onto the ground.
