Abstract
An anti-rotation device for suspending a load under a machine for lifting and moving this load includes a sling system provided with a fastener to the machine. It further includes a spreader beam, having a main longitudinal axis and a yaw rotation vertical transverse axis, including: a system for upper fastening to the sling system so it can be suspended in a substantially horizontal arrangement of its main longitudinal axis and free about its vertical transverse axis under the machine using the sling system; a system for lower fastening to the load, allowing driving of the load by the spreader beam about its vertical transverse axis. The spreader beam includes a propulsion unig disposed in such a way as to engage its rotation, selectively in one direction or in the other, about its vertical transverse axis when it is suspended from the machine via the sling system.
