QDH Type Marine Explosion-proof Pneumatic Hoist:
Pneumatic hoist is compressed air as the driving force to drive the pneumatic motor, after the speed change (deceleration) to increase torque after lifting the work
The utility model relates to a ship explosion-proof pneumatic hoist, which is mainly suitable for the exploitation of offshore oil fields and the daily transportation environment of an oil tanker, and has special requirements for corrosion protection of the sea and high temperature and low temperature.
