ABSTRACT:
A device for lifting, steerably moving and putting down a load includes a removable dolly which cooperates with an anchor plate fixed to the load. The removable dolly includes a chassis provided at its front part with a lifting and abutment system which cooperates with a complementary system on the anchor plate, the chassis being lockable to this plate. A steering system embodies two wheels mounted individually on the chassis and a set of links which hold the wheels parallel at all times. An orientable maneuvering bar is pivoted to the chassis and to the set of links. A locking arrangement is provided for selectively locking the maneuvering bar relative to the chassis. A device of this kind can be used to move and to position equipment to be slung underneath an aircraft.
