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.
