Abstract
A control arrangement for a fluid pressure operated hoist has a load mounted handle assembly including tubular handle portion slidable on a support rod attached to the hoist cable, and a bracket fixed at one end to the handle and extending alongside and offset from said support rod. A three position spring centered valve is mounted to the bracket, with a pair of pins each engaging one end of a valve element and a respective fixed flange on the support rod allowing valve operation by movement of the handle to block, vent, or pressurize a hoist fluid chamber to hold, lower, or raise the load.
