There is disclosed a clutch/brake mechanism of the 'disc' type wherein the coacting friction producing members are severally configured of frusto-conical and planar form whereby sealing contact is maintained at the peripheral surfaces thereof when in a brake-released condition to thereby prevent entrance of external contaminants into the brake-clutch mechanism.

Clutch/brake mechanism

A device for precisely positioning a hoist suspended load which operates by temporarily releasing the hoist brake for a predetermined limited time period without actuating the hoist motor so that the load is lowered through a small incremental distance by the influence of its own weight. A control signal may be generated by a delay timer, a repeat cycle timer, a digital timing device or a device for detecting the degree of movement of the load carried by the hoist.
