<p>The device uses electrically controlled operating cylinders (10,11) coupled to a hydraulic pump (17). The diesel engine (12) for driving the lorry is also coupled to an electrical generator (14), across which a storage battery (15) and the electric motor (16) for driving the hydraulic pump (17) are connected in parallel. Pref. the control device (22) for the operating cylinders (10,11) is coupled to the control unit (21) for the electric motor (16). The diesel engine (12) pref. has a take-off coupling driving a 3-phase generator (14) coupled to the battery (15) and the pump motor (16) via a rectifier (18).</p> |
