What should you pay attention to when using a hand chain hoist?

The hand chain hoist is also called the fairy gourd, Jinbuluo, and manual hoist. It is a manual lifting machine that is simple to use and easy to carry. It is also called "chain hoist" or "inverted chain". It is suitable for short-distance lifting of small equipment and cargo, and the lifting capacity generally does not exceed 100T. The shell of the hand chain hoist is made of high-quality alloy steel, which is strong and wear-resistant and has high safety performance. When the hand chain hoist lifts the heavy object upward, pull the manual chain clockwise and the hand chain wheel rotates. When descending, pull the manual chain counterclockwise. The brake seat and the brake pad are separated. The ratchet wheel is stationary under the action of the pawl. The five-tooth long axis Drive the lifting sprocket to run in the opposite direction to lower the heavy object smoothly.

When using a hand chain hoist, you should pay attention to the following points:

1. The rated load cannot be exceeded.

2. It can only bear force vertically and cannot be pulled or hoisted crookedly.

3. Two hoists cannot lift the same weight at the same time.

4. The gourd structure cannot be changed (double chain to single chain)

5. The gourd should be handled with care to prevent deformation.

6. Do not use the chain if it is damaged.

The oversized objects and the special flatbed truck are fixed with Φ18.5MM wire rope buckles and M20 or above flower rail bolts and reverse chains. After that, the crawler tracks and the flatbed truck are then bundled with 2-4 strands of No. 8 iron wire in the front and back for loading. , When bundling and lifting with multiple bundles, it is strictly prohibited to bundle them on vulnerable parts or parts that cannot withstand the binding force. The exposed mating surfaces, protruding edges and corners of each machine part and the precision parts of the shaft head must be packaged and protected to prevent damage or accidents during transportation. When loading, the center of gravity of the machine parts must coincide with the center of the flatbed truck. Overloading, width, and height must not be allowed. The loading and bundling work must be carried out by experienced personnel. Both hand chain hoists and electric hoists have many uses. But they cannot replace each other. Because the chain hoist is manual after all, it is generally used in scenarios where there is no power supply. Electric hoists are generally used in factories, assembly lines and other scenarios. Because of their high frequency of use, they can effectively reduce labor costs and improve efficiency.
