ABSTRACT:
A support frame assembly for a hoisting device including a cable drum pulling means mounted between two side-end members and at least two longitudinal girders arranged between the end members so that the ends of the longitudinal girders are substantially fixed in position relative to the end members. In order to reduce the expense of assembling and weight of the cable winch, the end members are clamped together in a longitudinal direction with at least one clamping means so that the ends of the longitudinal girders are, as a result, substantially fixed in position relative to the side-end members, at least in the longitudinal direction.
