ABSTRACT:
A load handling device for transferring ISO flat racks, containers or the like, to and from a support comprising two spaced lifting arms (11) pivotally connected adjacent their lower ends (at 9) to said support (13) and hydraulic rams (40,41) for rocking said arms (11) in a vertical arc, and an extension arm (53) pivotally connected to the end of each lifting arm (11) remote from its pivotal connection (9) to the support (13) and further hydraulic rams (55,57) for rocking each extension arm (53) about its pivotal connection to its lifting arm (11) through a vertical arc extending to either side of the longitudinal axis of the lifting arm (11). Preferably, the various hydraulic rams are connected to the lifting and guide arms outboard of the arms, and the extension arms are extendable, and the whole device is fitted to a vehicle chassis, thus enabling flat racks, containers and the like to be transferred between the ground, the vehicle or another vehicle, including a railway wagon, without the railway overhead power lines being hit.
