FIELD: hydraulic drive.
SUBSTANCE: regenerative hydraulic drive of a timber truck with a trailer comprises hydraulic cylinders: outriggers, booms, handles, a slewing bearing, a regenerative mechanism of the towing device, and a pump unit. The pump unit includes a hydraulic pump, check valve, filter, hydraulic tank, and hydraulic valves. The recuperative mechanism is equipped with two hydraulic cylinders, safety and pressure-reducing valves, check valves controlled by pilot electromagnets, two three-position four-line and two-line normally closed hydraulic valves, suction, drain, suction-drain, pressure and flexible pipelines, and a pneumohydraulic accumulator.
EFFECT: functionality of the hydraulic drive is expanded.
