Abstract: A lever hoist including a housing, in which a load chain wheel and a drive shaft are rotatably mounted. A drive torque is transmittable to the drive shaft via a lever. A load chain is moveable via the load chain wheel. The ratchet wheel has an internal thread and is axially displaceable on a threaded portion of the drive shaft having a brake thread. A damping spring is on a drive-side portion of the drive shaft between the threaded portion and an outer stop. If the load chain is blocked, when the load no longer continues to slip in a sliding manner, the ratchet wheel is pushed against the pressure of the damping spring until the pawl body is displaced out of the drive teeth into the untoothed disengagement portion.

Abstract: 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.

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 swivelling 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.

Abstract: The invention relates to a lifting gear having a flexible drive and a traction drive movable by the flexible drive. The flexible drive can be actuated by a lever arm arranged to pivot, and in the region of the free end of the lever arm, a handle is connected to the lever arm by an articulated joint. The handle can be pivoted from a starting position into an operating position.
