Specification of lifting equipment

1,Lifting equipment usually has large structures and complex operating mechanisms, can perform lifting movements and horizontal movements. For example, a bridge crane can complete the movements of crane operation, trolley operation; The gate crane can complete 4 movements of crane operation, lifting, rotating and trolley operation. During operation, several movements in different directions are often operated at the same time, causes technical difficulty. 

2, The lifting device can lift many heavy objects of different loads. However, for some objects weighing hundreds of tons, even thousands of tons, some objects have tens of meters long, very irregular shapes such as loose particles, molten state, dangerous goods, flammable, explosive … The lifting process is complicated and dangerous.

3, Most lifting equipment needs to be operated in large spaces. Some requires additional rails and wheels (such as tower cranes, cranes, etc.); some require wheels or trackers to travel on the ground (such as: cars). Install an additional crane, crawler crane, etc.) in case it is used to travel on a rope (eg: air cargo and passenger lines).

4, Some helicopter machines that directly carry people on the guide rail need a platform or rope to lift movement (such as lifts, platform lifts, etc.), and their reliability directly affects  personal safety.

5, Lifting equipment has many moving and contact parts (such as hooks, ropes, etc.) which often come in direct contact with the lifting operator so there is a potential risk of accident.

6, Complex operating environment: From large-scale iron and steel complexes to modern ports, construction sites, railway hubs, tourist sites, all have operating machines; Workplaces often exists dangerous factors such as high temperature, high pressure, flammability, power transmission lines, strong magnetism, etc., pose threats to equipment and operators.

7, In the lifting industry, many people are often required to cooperate and work together. An activity requires the commander and other operators to cooperate skillfully, coordinate actions and observe each other. The operator must be able to deal with emergency situations on site.
