Product introduction

      The explosion-proof chain hoist uses aluminum bronze and beryllium bronze as the blank, and the explosion-proof chain hoist shell adopts H62 copper alloy material, and the rotating gear is subjected to high-temperature heat treatment to achieve high wear resistance of the gear. In the operation, the products will not generate mechanical sparks when they collide with each other, and do not detonate the gas in the inflammable and explosive places, thus effectively preventing fire accidents. 
      The working principle of the explosion-proof chain hoist: 
      by rotating the bracelet chain, the hand wheel starts to rotate, the friction plate ratchet and the brake seat (pressed into a body) rotate together, and the five-tooth long shaft rotates the plate gear, the four-tooth short shaft and the spline Hole gear. Thus, the hoisting sprocket of the device on the spline hole gear drives the hoisting chain to smoothly lift the weight. 
      Explosion-proof chain hoist is a kind of manual lifting device that is easy to use and easy to carry. The pulling force is light and self-weight, easy to carry, beautiful in appearance, small in size and durable. 
      Explosion-proof chain hoists can be combined with explosion-proof manual monorail trolleys to form manual lifting transport trolleys. Explosion-proof chain hoists can be widely used in petroleum, petrochemical, petrol stations, oil depots, gas production, chemical industry, military industry, electric power, mining, electronics, railways. In the dangerous environment of potential fire and explosion, the friction between the products in the operation will cause mechanical sparks, effectively prevent fire accidents and ensure national property and personal safety. It is also a special tool essential for mechanical manufacturing and mechanical maintenance.
