MQHGTD series of hydraulic control emergency manipulator of winding headstock gear
Purposes and features：
The product is a new-type product which is researched and developed by our company after introducing the foreign advanced and proven technology and combining the actual conditions of domestic engineering. The product has obtained the national patent protection (Patent No. ZL2011100912742) .As the emergency operation device for winding headstock gear, the product can be widely applied to the winding headstock gear used in the water conservancy, hydropower, river levee, reclamation and port engineering. When the winding headstock gear motor is under normal operation, the manually-operated clutch will be opened, therefore, the product will have no influence on the normal work of headstock gear; if the product shall make emergency operation, the manually-operated clutch shall be closed.
The product is a kind of emergency equipment which can keep the lifting function when the winding headstock gear suffers from power failure or the motor is out of order. In cooperation with DLD series power unit, this product may allow emergency lifting and horizontal traction of the winch.
The primary power supply, secondary power supply and diesel engine are all powered devices, so these devices Open and close the gates through circuit. But the emergency manipulator Open and close the gate when there is no power!! In case of earthquake, typhoon, heavy rain, circuit or motor failure, even Motor failure, the emergency manipulator can urgently Open and close the gate when there is no power or motor. Emergency manipulator of hoist—airbag of hoist!
How to select：
At corresponding revolutions of the winch motor, select the base number according to the power(Coefficient of capacity increase SF≥1.15). And, determine the product model by selecting additional number as per performance and direction of rotation.
Standard type data sheet for power selection：
