Working principle and application scope of explosion-proof chain hoist


     Working principle: Explosion-proof chain hoist. Working principle: By dragging the bracelet chain and the bracelet wheel, the friction plate ratchet and the brake seat (pressed into one) rotate together. The five-tooth long shaft turns the plate gear, four-tooth short shaft and Splined hole gear. Therefore, the hoisting sprocket installed on the spline hole gear drives the hoisting chain and smoothly lifts the weight.

     Scope of use: Explosion-proof chain hoists can be widely used in petroleum, petrochemical, oil stations, oil depots, gas production, chemical industry, military industry, power, mining, electronics, railways, and other potential fire and explosion hazardous environments, products in operation Friction and impact will not produce mechanical sparks, effectively prevent fire accidents and ensure national property and personal safety. It is also an indispensable special tool for machine manufacturing and machine maintenance.
