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.
