The explosion-proof chain block is made of aluminum bronze and beryllium bronze. The shell of the explosion-proof chain block is made of H62 copper alloy. The rotating gear is heat-treated at high temperature to achieve high wear resistance. In the operation, the products will not produce mechanical sparks due to mutual friction and impact, and the gas will not be ignited in flammable and explosive places, so as to effectively prevent fire accidents.

Working principle
By dragging the chain and the chain wheel, the friction plate ratchet wheel and the brake seat (pressed into one) rotate together, and the five tooth long shaft turns the plate gear, the four tooth short shaft and the spline hole gear. Thus, the lifting chain wheel installed on the spline hole gear drives the lifting chain to lift the weight smoothly.
Explosion proof chain block is a kind of simple and portable manual lifting machinery, with small pulling force, light weight, easy to carry, beautiful appearance, small size and durable.
The explosion-proof chain block can be used with explosion-proof manual monorail car to form a manual lifting and transportation car. The explosion-proof chain block can be widely used in petroleum, petrochemical, oil station, oil depot, gas production, chemical, military, electric power, mining, electronics, railway and other dangerous environments with potential fire and explosion. Mechanical sparks will be generated when the products collide with each other during operation, which can effectively prevent the explosion Fire accidents, to ensure the safety of state property and people. It is also an indispensable special tool for machinery manufacturing and maintenance.
