What are the characteristics of explosion-proof chain hoist?

Explosion-proof chain hoist is an easy-to-use and easy-to-carry manual hoisting machine with small pulling force, light weight, easy to carry, beautiful appearance, small size, and durability. Explosion-proof chain hoists are made of aluminum bronze and beryllium bronze. The shell of the chain hoist is made of H62 copper alloy. The rotating gear is heat-treated at high temperature to achieve high abrasion resistance.

Use range

Explosion-proof chain hoist can be widely used in petroleum, petrochemical, petrol station, oil depot, gas extraction, chemical industry, military industry, electric power, mining, electronics, railway, and other potential fire and explosion dangerous environments. The products rub against each other during operation it will not generate mechanical sparks, effectively prevent fire accidents, and ensure national property and personal safety. It is also an indispensable special tool for machinery manufacturing and machinery maintenance.

Rules of use

1. Overload use 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 it will slowly descend 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 the weight is raised or lowered, when pulling the bracelet, the force should be even and gentle. If the operator finds that the pull force is greater than the normal pull force, he should stop using it immediately. Maintenance method: After use, the gourd should be cleaned and coated with rust-proof grease and stored in a dry place. Maintenance and overhaul should be performed by people who are more familiar with hoist mechanisms to prevent people 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 performed to confirm that it is working 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 the brake from malfunctioning and the self-falling of the medium.
