Abstract
A traveling crane includes a longitudinal beam displaceable on rails. A traveler having a hoisting winch with a cable drum is displaceable in a transverse direction, and is operable to wind a cable reeved through at least one lower block. The hoisting winch is displaceable relative to the traveler in a hoisting winch travel direction such that a cable run out point remains in one location relative to the longitudinal extent of the cable drum. Two winching hoists are provided which are displaceable transversely to the longitudinal beam with respective cable drums thereof being disposed parallel to and spaced from each other. A common cable can be wound up and down by the two cable drums, and the two cable drums include cable grooves running in opposite directions. The two cable drums are operable in the opposite direction of rotation for lifting and lowering a load.
