Abstract

See full text

A lever hoist includes a housing in which a load chain wheel and a drive shaft driving the load chain wheel via a transmission are rotatably mounted, as well as a safety brake. A load chain is movable via the load chain wheel. The safety brake implements emergency braking in response to excessive rotational speed of the drive shaft. The safety brake includes a locking disc with teeth and a control disc with control cams. The locking disc and the control disc are rotatable in a limited manner. A catch hook is movable in a swiveling manner and has a latch contour at a front end and a sensing contour at a rear end. The sensing contour rests on the control disc. When a defined rotational speed is exceeded, the sensing contour lifts off the control disc. The latch contour engages with a locking tooth of the locking disc.
