JQHS series pneumatic winch is a kind of winch device which is powered by pneumatic motor and drives the drum through gear reduction mechanism to achieve heavy weight traction and lifting. It has the advantages of compact structure, convenient operation, safe and reliable work, simple maintenance, smooth operation and stepless variable speed. As explosion-proof traction, lifting power device, especially suitable for oil field (including ocean), geological drilling, mining and explosive, flammable gas and other places.

1, in the use of qualitative analysis of the motor, if you want to run and stop smoothly, it should be in the control circuit design of the essential pressure control or flow monitoring method.

2. When the water hydraulic motor is used as the driving force of the lifting tool or the walking machine, the network speed limiting valve should be set as far as possible to prevent the rapid landing of the lifting or the downhill of the vehicle and other lifting systems from limiting the network speed and causing serious production safety accidents.

3. Because the hydraulic motor of Ningbo city will always leak, the inlet and outlet of the low-speed hydraulic motor will be closed to carry out the braking system. It will still appear a slow load.

4. When you must operate in full load, you should pay attention to the operation torque value of the low-speed hydraulic motor, because the operation torque of the rotary hydraulic motor is smaller than the rated current torque. If you ignore it, it is likely to make the working mechanism unable to operate.
