How to prevent injuries caused by chain hoists?

The hand chain hoist, commonly known as the weight not falling, chain hoist, and chain hoist, is a very convenient and simple small lifting tool to use. Although it may appear to have a simple structure that everyone can use, in reality, if one does not understand its mechanical performance and usage rules, it is very easy to cause various accidents. To avoid accidents caused by operation, we should do the following:

1. Strengthen maintenance and use correctly.

Hand chain hoists should be stored in a well ventilated and dry warehouse. During use on the construction site, rain and waterproof measures should be taken to prevent rusting and prevent some parts from functioning properly and flexibly. It is strictly prohibited to throw, smash, bump, collide, etc. randomly to prevent deformation of some parts. Regularly lubricate the rotating parts. During use, it is necessary to strictly comply with the relevant provisions in the "Precautions for the Use of Hand Chain Hoists" and the "Safety Work Regulations for Electric Power Construction".

2. Cannot be used under overload. Before using the chain hoist, first check whether the weight of the object to be lifted matches the rated load of the chain hoist, and never use it under overload. During use, the number of zippers should not be increased arbitrarily. Only one person is allowed to pull 0.5 tons to 2 tons; 3-5 tons can be pulled by 1-2 people; Two people pull 5-8 tons; 10-15 tons can be pulled by 3 people. If these regulations are violated and rough operation is carried out, it will cause damage to the chain hoist and even accidents.

3. Regularly inspect and conduct load tests.

According to relevant regulations, the chain hoist should undergo regular maintenance inspections and load tests. Some units do not implement these regulations now, as long as they can be used, they can be scrapped if they are damaged, and they do not maintain or conduct load tests, which leaves a hidden danger of accidents for the normal use of the chain hoist. When using a chain hoist, it is necessary to establish a ledger, which is managed and distributed by a dedicated person. Damaged items must be resolutely eliminated, and after repair, compliance testing must be conducted before use.

4. Ensure quality during procurement. In recent years, due to inadequate management, there has been a proliferation of counterfeit and inferior products in the market. Hand chain hoists also have a large number of substandard products put on the market. Therefore, when purchasing, it is important to take quality and reliable branded products seriously, and always adhere to purchasing the same branded products. Before entering the warehouse, careful inspection, identification, and testing should be carried out.

5. Strengthen the learning of basic knowledge on safe use of chain hoists. Arrange time and organize employees to learn about the safe use of chain hoists.
