Abstract
The present invention relates to a system for spreading and depositing a spanning beam from a vehicle wherein, in the transport position of the spanning beam on the vehicle, the outer extreme element of the spanning beam is pivotally supported and maintained at its free end by a mobile support device of the vehicle occupying a raised position while the inner extreme element of the spanning beam rests on the outer extreme element along same and wherein the spanning beam can be raised by winding of the working cable on a winch of the vehicle into a position where the inner extreme element is pivotally supported at its free end by the support device with concomitant release of the free end of the outer extreme element from the device.
