Abstract (en)
[origin: CA3153687A1] The invention relates to lifting gear, in particular a lever hoist 1. This comprises a housing 2 in which a load chain wheel 17 and a driveshaft 20 driving the load chain wheel 17 via a transmission 18 are rotatably mounted, as well as a drive 12, a load pressure brake 16 and a safety brake 30. A load chain 10 can be moved via the load chain wheel 17. The safety brake 30 brings about an emergency braking in the event of excessive rotational speed of the driveshaft 20. The safety brake 30 has a locking disc 32 with locking teeth 33 and a control disc 34 with control cams 35, as well as a catch hook 36. The locking disc 32 and the control disc 34 can be rotated in a limited manner in relation to one another. The rotation is limited by a rotational travel limiter 47.
