Abstract

A bridge or gantry crane, in particular for handling ISO containers, includes a crane cart that can move along a crane support in the direction of travel of the cart. The cart supports at least one mast that can move in a vertical lift and lowering direction, and a load supporting means for containers being suspended at the mast. In order to optimize the handling rate of a bridge or gantry crane, at least one second mast is provided including a second load supporting means disposed behind and at a distance from a first mast as seen in the direction of travel (K) of the cart.
