Abstract: A hoist drum for a fiber rope drive for high-strength fiber ropes such as crane hoists, boom adjustment or trolley traveling gear, and the like, comprising a drum body for winding up the fiber rope, guard plates encompassing the drum body, and a rope end fastening apparatus for fastening a rope end to the hoist drum. The rope end fastening apparatus of the hoist drum comprises two strand guiding passages that are disposed next to one another and that lead to a rope deflection element at which the rope end can be turned around and back so that one respective rope strand comes to lie in the two strand guiding passages; and furthermore comprises a clamping apparatus associated with the strand guiding passages for clamping at least the rope strand that is turned back around the rope deflection element in the strand guiding passage associated with the rope strand.

Abstract: The present invention relates to a hoisting winch assembly comprising at least two preferably axially parallel drums spaced from each other axially, which can be driven in synchronism with each other by two motors via a transmission assembly. The invention furthermore relates to a crane, in particular a gantry and/or container crane, with such hoisting winch assembly. According to the invention, the transmission assembly has at least two separate gear trains, so that each motor is in drive connection with one drum each via a separate gear train. As compared to a common transmission to which both motors are connected, the separate gear trains can be configured significantly lighter and smaller, as no longer the power of both motors added up, but only the power of one motor must be transmitted. Nevertheless, high hoisting powers can be provided on the whole, as each motor must drive only one drum.
