A lever hoist includes a housing in which a load chain wheel and a driveshaft driving the load chain wheel are mounted, as well as a safety brake. A load chain is movable via the load chain wheel. The safety brake brings about an emergency braking in the event of excessive rotational speed of the driveshaft. The safety brake has a locking disc with teeth and a control disc with control cams. The locking disc and the control disc are rotatable in relation to one another in a limited manner. A catch hook is movable in a swivelling manner and has a latch contour and a sensing contour. The sensing contour rests on the control. In response to exceeding a defined rotational speed, the sensing contour lifts off the control disc. The latch contour rotates towards the locking disc and engages with a locking tooth of the locking disc.
