Crane equipment working characteristics and existing risk factors

 

1. Hoisting equipment is usually equipped with a large structure and a relatively complex mechanism. In the operation process, it is often operated in several directions at the same time, which is technically difficult.

 

2. Some hoisting equipment (only refers to the construction of lifts, etc.), need to directly carry personnel to do lifting movement, its reliability directly affects personal safety.

 

3. It is required to operate in a large range with large activity space. Once an accident is caused, the affected area will also be large.

 

4. There are many kinds of heavy loads that can be lifted, and the loads vary. Some heavy weight up to hundreds of tons, large and irregular volume, there are loose particles, thermal fusion and flammable and explosive dangerous goods, so that the process of lifting complex and dangerous.

 

5. Exposed to a large number of active components, and often in direct contact with operators, potentially many accidental risk factors.

 

6. The operation environment is complicated, such as involving enterprises, ports, construction sites and other sites, high temperature, high pressure, inflammable and explosive and other environmental risk factors, posing a threat to equipment and operators.

 

7. Many people are often required to cooperate in the operation, which requires higher requirements on the commander, operator and starting heavy industry.

 

According to relevant statistics, the number of work-related deaths caused by crane injury accidents in China accounts for about 15% of the total number of work-related deaths in all industrial enterprises every year. In order to ensure the safe operation of hoisting machinery, the state will be listed as special equipment to manage, many enterprises have to manage hoisting equipment as the key link of safety production.
