A method for monitoring a chain hoist having an electric drive motor which is connected on the output side, via a friction clutch, to a transmission, wherein, via a sensor, a speed of the transmission is sensed, and the sensed speed of the transmission is compared with an operating speed of the drive motor by means of a control device. In order to achieve safe and efficient operation of the chain hoist, a vertical position of the load handling device of the chain hoist is also determined by means of the control device. The invention also relates to a chain hoist having a control device which is designed and configured to carry out the method according to the invention.

A shut-down buffer for a lifting device, in particular a chain hoist, includes two opposing end surfaces and at least two mutually spaced web elements extending between the end surfaces. The shut-down buffer is defined by the end surfaces, between which a through-opening for passage of a load-bearing element of the lifting device extends through the shut-down buffer.

An assembly kit for cable winches, comprising a cable drum, a drive motor, a transmission unit, and a supporting frame, where the assembly kit includes various transmission housing parts for the transmission unit in order to enable the assembly of a cable winch in a C shape or in a quasi-coaxial shape. A method for converting a cable winch, comprising a cable drum, a drive motor, a transmission unit, and a supporting frame, between a C-shape arrangement and a quasi-coaxial-shape arrangement, for which purpose the transmission unit, in the case of the use of different housings, in particular specific housing shells that can be assembled in order to form the different housings, is assembled differently for the C shape or coaxial shape while the same parts, in particular identical shafts, are used within the particular housing.

A chain block with a drive motor () with a motor shaft (), which is connected at the take-off side via a slip clutch () to a transmission input shaft (), having a first gear () and mounted in a housing () by pivot bearings (), of an at least one-stage transmission (). In order to create a simple design of chain block with a slip clutch, the transmission input shaft () is to be mounted floating in the pivot bearings () in order to change the frictional force of the slip clutch ().
