IMPROVED HOIST OR THE LIKE Abstract of the Disclosure The improved hoist includes a direct current brake and a control therefor. In the brake control, the AC current is rectified with DC current being sent to the brake solenoid. When the hoist is operating, the brake solenoid is energized to hold the brake in the unactivated position. A timer and power reduction means are utilized to reduce the power on the solenoid while the hoist is in operation, thus reducing the energy expended while the hoist is in operation. The operating speed of the brake is increased since less power must be dissipated from the solenoid before the brake can be actuated.
