The electro-hydraulic grab is a hydraulic system that comes with a motor, a hydraulic pump, etc., and is opened and closed by an external power supply. The grapple controls the opening and closing of the grab by means of a positive reversal of the motor or a hydraulic reversing valve. Electro-hydraulic multi-claw bucket is an effective tool for loading and unloading stones, scrap, garbage, etc. in a variety of harsh environments. The grab comes with a hydraulic system. The main components of the valve system, seals, and valve blocks of the hydraulic system are made of European and American brands. The hydraulic pump uses a constant power pump and adopts a hydraulic servo system. The pressure change of the system can effectively control the output of the pump. When the maximum pressure is reached, the flow rate of the pump is extremely low, thereby greatly reducing the overflow, reducing the energy consumption, reducing the oil temperature, and using the continuous work for a long time, which greatly improves the production efficiency. Grab structure is simple, easy to operate, can work in a variety of harsh environments. The unique sacral curve is particularly suitable for the loading and unloading of various types of bulk cargo. The upper part of the grab has a cable interface to facilitate the connection with the crane.
