Lifting Tools Small Size, Simple Structure

- Sep 30, 2017 -

They can be used alone, and some can also supporting the use of. Some light and small lifting equipment of the lifting capacity is great, such as the hydraulic jack from the weight of 750 tons. Mine hoists and hopper lifts for vertical or near vertical movements, with a fixed lift road. The overhead monorail system has a rigid suspension track that can transport the material to the plant parts and to the outside of the plant.

The basic mechanism of lifting gear

The use of various types of lifting tools are different, the structure is very different, but have completed the lifting of the basic initiatives of the lifting mechanism. The material can be lifted by a flexible piece such as a wire rope or a lifting chain, or by a screw or other rigid part.

1) Lifting tools are usually small in size, simple in structure, capable of lifting movements and horizontal movements.

2) Lifting tools are hoisting a wide variety of loads, 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 tool, need to run in a larger space, and some to install rails and wheels (such as tower crane, bridge crane, etc.); some to wear tires or track 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 accident caused by a larger range.

4) Some lifting tools require direct carrier personnel to carry out movements (such as elevators, lifting platforms, etc.) on rails, platforms or wire ropes, and their reliability directly affects personal safety.

5) Lifting tools exposed, the activities of the 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-scale 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 the lifting of the tool design, manufacture, installation and maintenance and other aspects of a slight negligence, it may cause casualties or equipment accidents. On the one hand caused the casualties, on the other hand will cause great economic losses.

 Lifting tools are mainly used for handling items, equipped with grab can be transported after the coal, ore, grain and the like bulk material, equipped with Sheng barrels can be lifted steel and other liquid materials. Some lifting tools such as elevators can also be used to maneuver. In some applications, lifting equipment is still a critical operating tool, such as in the port and the station loading and unloading materials crane is a critical tool for lifting tools.
