Adopting pneumatic motor as power, Pneumatic winch model QDJC series can tow and lift heavy goods through speed-reducing gearbox to drive roll. It has the advantages of compact structure, convenient operation, safety and reliable operating, simple maintenance, smoothly running and stepless speed-changing etc.

It is suitably used in oil field, well-drilling in oil field, mine-exploiting and other place with inflammable or easy exploding air. It applies to areas below 1000 metres above sea level and the temperature of the environment between -40°C to 60°C.

Air balancers provide ergonomic lift assist that interacts with the operator, making heavy objects easy to move. Precise, stain-free positioning leaves both of the operators' hands free to raise, lower, or shift loads with virtually no resistance. This freedom of operation and easy control makes tasks like lifting and moving heavy loads in manufacturing, warehousing and other operations safer, easier and faster.
