Abstract
A hoisting device, especially a cable or chain block, with a hoisting transmission having at least one shaft and with a hoisting load measuring mechanism. In order to determine the hoisting load as accurately as possible and possibly independent of the reeving and without additional structural height, the hoisting load has at least one sensor for detecting the deformation of the shaft produced by the hoisting load and the detected deformation is used as a quantity in determining the hoisting load.
