Abstract:
1. A dumping system adapted for suspension from a support, said system comprising: (a) a container capable of dumping material therefrom by selectively tilting said container, said container being vertically movable with respect to said support by a selectively extensible and retractable hoist line suspending said container from said support; (b) a first pulley attached by a first attachment element to said container so that said hoist line can be wrapped under said first pulley to suspend said container; (c) a second pulley attachable to said support so that said hoist line can be wrapped over said second pulley to extend from said first pulley to said second pulley; (d) a second attachment element on said container to which said hoist line can be attached to extend from said second pulley to suspend said container; and (e) a selectively-actuated brake capable of selectively preventing rotation of said second pulley while permitting rotation of said first pulley, so that said container is tiltable to dump said material therefrom by moving extension of a portion of said hoist line from said support while said brake is actuated, without corresponding moving extension of a second portion of said hoist line from said second pulley.
