1, usually lifting tools with compact structure and other characteristics, to complete the horizontal and vertical movement.
2, lifting a wide range of tools, handling, handling of heavy objects are also different, the load is also changing. Usually the nature of the lifting of the goods, the choice of Lifting Tools is also different.
3, some lifting tools need to be in a wider space within the construction, and some lifting tools also need to install rails, wheels and other requirements to meet the walking requirements, usually the lifting tool of a wide range of operations, resulting in the scope of the impact of security incidents larger.
4, some open space in the use of lifting tools, will be directly exposed to the sun, the existence of occasional risk factors are more.
5, some lifting tools need more people together to complete the construction requirements in coordination. Usually more than with the completion of the project, the technical difficulty is greater.
1) Lifting tools are usually small in size, simple in structure, capable of lifting movements and horizontal movements.
2) Lifting Tools lifting a variety of heavy objects, the load is changing. Some heavy objects weighing hundreds of tons or even thousands of tons, and some objects up to tens of meters, the shape is also very irregular, there are scattered, hot melt state, flammable and explosive dangerous goods, lifting process complex Danger.
3) part of the Lifting Tools, need to operate in a larger space, and some to install rails and wheels (such as tower crane, bridge crane, etc.); some to install tires or crawlers walking on the ground (such as car cranes , Crawler, etc.); some need to walk on the rope (such as passenger, cargo aerial ropeway), the larger space, once the impact of the scope of the accident is also larger.
4) Some lifting tools need direct transport personnel in the rails, platforms or wire rope to do lifting movements (such as elevators, lifting platform, etc.), its reliability directly affect personal safety.
5) Lifting tools exposed, the activities of more parts, and often with the lifting operations personnel in direct contact (such as hooks, wire rope, etc.), potentially many occasional risk factors.
6) complex operating environment. From the large steel joint enterprises, to the modern port, construction sites, railway hubs, tourist attractions, have lifting tools in operation; workplace often encounter high temperature, high pressure, flammable and explosive, transmission lines, strong magnetic and other risk factors , Posing a threat to equipment and operators.
7) Lifting tool operations often require more people to cooperate with each other. An operation, requiring command, strapping, driving and other operating personnel with skilled, coordinated action, mutual care. Operators should have the ability to handle on-site emergencies. There is a great deal of difficulty in the close cooperation between multiple operators.
Lifting tool of the above characteristics, decided that it has a great relationship with the safety of production. If there is a slight negligence in the design, manufacture, installation and maintenance of the Lifting Tools, it may result in casualties or equipment accidents. On the one hand caused the casualties, on the other hand will cause great economic losses.
