154HC Mast Section The working characteristics and risk factors
1. Hoisting machinery is usually equipped with a large structure and a relatively complex mechanism. In the process of operation, it is often operated in several different directions at the same time, which makes the technology difficult.
2. There are many kinds of heavy objects that can be lifted, and the load is variable. Some heavy objects weigh hundreds of tons, are large and irregular, and there are also bulk, heat fusion, inflammable and explosive dangerous goods, which make the hoisting process complex and dangerous.
3. It needs to operate in a large range, with a large space for activities. Once an accident is caused, the area affected is also large.
4. Some hoisting machines (only refer to construction elevators, etc.) need to carry personnel directly for lifting movement, whose reliability directly affects personal safety.
5. There are many exposed parts, which are often in direct contact with operators, and there are many potential accidental risk factors.
6. The operation environment is complex, such as involving enterprises, ports, construction sites and other places, involving environmental risk factors such as high temperature, high pressure, inflammable and explosive, which poses a threat to equipment and operators
7. Many people are often needed to cooperate in the operation, which requires high requirements for the commander, operator and rigger.
