i Working Principle
JQHSP-50*12 is a kind of manual operated single drum type air winch. It adopts compressed air as power to drive the tmh17 piston air motor, by operating manual diversion valve on the motor, driving drum via two grades gears(to reduce transmitting speed and enlarge torque)So as to lift and drag heavy cargoes. as well, the winch can perform hoisting, lowering and stopping actions to the wire rope.
iii Application Places
this winch is widely used for drilling platform, marines, mining, engineering sites, platform of oilfield off-sea and inland etc. to drag and pull heavy cargoes.
Why choose us: remote control distance could reach 6-15m.
1. Equipped with cylinder air brake(5ton type), which enables the winch automatically in brake when stops.
