A chain block with a drive motor ( 2 ) and with a transmission ( 3 ), connected to the drive motor ( 2 ) at the take-off side, with a transmission output shaft ( 4 ), on which a chain wheel ( 5 ) is rigidly arranged for pulling a chain. In order to create a compact chain block, the chain wheel ( 5 ) faces the drive motor ( 2 ) at its take-off end face ( 19 ) and the outer circumference of the chain wheel ( 5 ) reaches into the imaginary extension of the outer contour of the drive motor ( 2 ).
