    Introduction to the use rules and working principles of explosion-proof chain hoists


Description: Explosion-proof chain hoist is a kind of easy-to-use and easy-to-carry manual lifting machinery. Explosion-proof chain hoist can be used with explosion-proof manual monorail trolley to form a manual lifting and transporting trolley. Explosion-proof chain hoist can be widely used in petroleum, petrochemical , Petrol station, oil depot, gas production, chemical industry, military industry, electric power, mining, electronics, railway, and other dangerous environments with potential fire and explosion, friction and collision between products during operation will not generate mechanical sparks, effectively preventing fire accidents Ensure national property and personal safety. It is also an indispensable special tool for machinery manufacturing and machinery maintenance.

Explosion-proof chain hoist

The use rules of explosion-proof chain hoists are as follows:

1. Overloading is strictly prohibited. It is strictly forbidden to operate with power other than human power. Before use, make sure that the parts are intact, the transmission part and the lifting chain are well lubricated, and the idling condition is normal. Check whether the upper and lower hooks are fastened before lifting. Do not erroneously carry heavy objects on the tip.

2. The explosion-proof chain hoist lifting chain should be hung vertically, there must be no twisted chain links, and the lower hook rack of the double-row chain must not be flipped. The operator should stand on the same plane as the bracelet sprocket and drag the bracelet to rotate the bracelet in a clockwise direction to raise the weight. Pull the bracelet in the opposite direction and slowly fall at noon. When lifting heavy objects, personnel are strictly prohibited from doing any work or walking under the heavy objects to avoid personal accidents.

3. During the lifting process of the explosion-proof chain hoist, no matter how heavy the weight is going up or down, when pulling the bracelet, the force should be even and gentle. If the operator finds that the pulling force is greater than the normal pulling force, he should stop using it immediately. Maintenance method: After use, the gourd should be cleaned and coated with anti-rust grease and stored in a dry place. Maintenance and inspection should be carried out by persons who are more familiar with hoist mechanisms to prevent those who do not understand the principle of performance of the machine from disassembling at will.

4. After cleaning and maintenance of explosion-proof chain hoist, no-load test should be carried out to confirm that it works normally and the brake can be delivered before use. The friction surface of the brake must be kept clean. The brake part should be inspected frequently to prevent brake failure and self-dropping of medium objects.

Working principle of explosion-proof chain hoist : By dragging the bracelet chain and the bracelet sprocket, the friction disc ratchet and the brake seat (compressed into one body) rotate together, and the five-tooth long shaft rotates the tablet gear, the four-tooth short shaft and the spline hole gear. Therefore, the lifting sprocket set on the spline hole gear drives the lifting chain and smoothly lifts the heavy object.
