FIELD: mechanical engineering.
SUBSTANCE: invention relates to construction and road vehicles and can be used in loaders. The hydraulic drive of the loader boom contains a hydraulic control valve 3 with hydraulic cylinders 2 for lifting the boom, which is connected to the hydraulic accumulator 6 through a controlled hydraulic valve 4 and an adjustable hydraulic throttle 9. In transport mode, when moving the loader with a filled or empty bucket, the function of damping the vibrations of the working equipment relative to the base machine is activated. During the periods of material intake into the bucket and its unloading, the damping function is blocked. The invention is aimed at simplifying the device, reducing the cost and increasing the reliability of the vibration damping system of working equipment in transport mode.
EFFECT: as a result, an increase in movement speed and productivity is achieved.
