A chain block with a drive motor ( 2 ) with a motor shaft ( 11 ), which is connected at the take-off side via a slip clutch ( 50 ) to a transmission input shaft ( 14 ), having a first gear ( 18 a) and mounted in a housing ( 1 ) by pivot bearings ( 13, 13 a), of an at least one-stage transmission ( 3 ). In order to create a simple design of chain block with a slip clutch, the transmission input shaft ( 14 ) is to be mounted floating in the pivot bearings ( 13, 13 a) in order to change the frictional force of the slip clutch ( 50 ).
