JQHS series pneumatic winches (also known as XJFH series pneumatic winches due to the implementation of double-standard model writing method) are powered by piston air motors, and drive the reel through the reduction mechanism to realize the pneumatic support structure on the reel for heavy traction or lifting. JQHS series pneumatic winches can be divided into common high seat, ordinary low seat, flange seat, trapezoidal buckle seat, straight thread buckle seat, lug plate seat, bent plate seat and other base types according to the structure of the base. And the combination can be divided into single brake (hand brake), double brake (hand brake + foot brake, hand brake + cylinder off brake, hand brake + disc brake off brake), three brakes (hand brake + foot brake + cylinder off brake). Users can choose according to actual operation needs.
