FIELD: transportation.SUBSTANCE: device (10) for control of excavator motion speed comprises a driving diesel or petrol engine (1), a hydraulic pump (2), a regulating slide valve (4), a ground drive motor (5), a hydraulic drive of an excavator bucket, a controller. Speed of motion of the ground drive motor (5) is controlled by the speed of the driving motor (1), while the hydraulic drive of the excavator bucket does not generate any drive capacity. Also the method is proposed to regulate speed of excavator drive.EFFECT: development of pressure in an injection line, which is closest to pressure pulled by load, which is required for desired speed of motion, causing losses, limitation of pressure reduction to required pressure, is thus removed.10 cl, 5 dwg |
