Abstract

For controlling the movements of the jibs of a first crane and at least a second crane mounted in opposed relation on fixed stands on each side of a handling area so that a load suspended from the two cranes maintains a constant predetermined orientation within said handling area irrespective of the swinging and steeve of the first crane. The device comprises a first movable arm connected to the jib of the first crane so as to reproduce the movements in swinging and steeve of the first crane, a second movable arm connected to the jib of the second crane and mechanically connected to the first arm in such manner as to effect movements corresponding to the position that the jib of the second crane must occupy in accordance with the position of the jib of the first crane given by the first arm.
