The motor-hydraulic grab has its own hydraulic system and is opened and closed by an external power supply. The motor-hydraulic grab can be engaged in the effective handling of grain, fertilizer, yellow sand, coal, mineral powder, ore, cement, scrap steel, garbage and other bulk cargo in a variety of harsh environments, relying on a reliable and fully enclosed hydraulic control system. FINER motor-hydraulic grab uses the best low-pressure, low-flow unloading technology to minimize the amount of heat generated by the grab and enhance the reliability of the continuous operation of the grab.
According to the different electric control method, the grab can choose the positive and negative motor control or the solenoid valve control.

 
At the cold poles, FINER motor-hydraulic grab can operate at -30 ° C with cryogenic condensate resistant hydraulic oil, and the main steel structure of the grab can operate normally at -40 ° C
Grab can choose visual level gauge, tilt switch, oil temperature level sensor.
Hydraulic coupling cable reel is used for the motor-hydraulic grab for the ship crane (such as the crane), which can ensure the smooth retracting and rewinding of the cable when the cable and the grab are lowered simultaneously, and effectively prevent cable damage and breakage.
Underwater motor-hydraulic grab with water leakage detection.
