Abstract
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.
