What are the commonly used lifting tools?
The commonly used lifting tools and equipment include jacks, chain hoists, shackles, rope clips, hooks, manual chain hoists, winches, pulleys and pulley groups.
Pulleys and pulley groups are commonly used lifting tools in lifting, hoisting and handling operations.
Jacks are widely used in lifting work. They can lift heavy machinery with very little force, and can also correct discrepancies and deformations in equipment installation and components.
The shackle, also known as a decoupling device, is used to connect ropes or rope loops to the lifting ring of the component. It is a widely used connecting tool in lifting operations.
Rope clips are mainly used for temporary connection of wire ropes and fixing the hand rope when the wire rope is wound around the pulley group, and for fixing the cable wind rope head on the cable wind rope gripper.
Hooks are divided into single hooks and double hooks according to their appearance. Hooks are divided into forged hooks and plate hooks according to their forging methods.
The lifting of components requires the preparation of a special construction plan, which is also a component of the construction organization design.
The manual chain hoist is a lightweight and convenient manual traction device. It has the characteristics of compact structure, small size, light weight, convenient carrying and stable performance.
The winch is a widely used manual traction tool, mainly used for lifting and handling operations where the lifting speed is not fast, there is no electric winding machine, there is no power supply in remote areas, and the traction force is not large.
The chain hoist, also known as a manual lever hoist, can be used to lift light-weight components, tension cable wind ropes, and bind ropes during component or equipment transportation.
Application of lifting tools
Lifting tools are mainly used for handling assembled goods. Equipped with grabs, they can handle granular materials such as coal, ore, and grain, and equipped with barrels, they can lift liquid materials such as molten steel. Some lifting tools, such as elevators, can also be used to transport people. In some usage scenarios, lifting equipment is still the main tool for operations, such as cranes used for loading and unloading materials at ports and stations.
What are the classifications of lifting tools?
Lifting tools can be divided into several categories according to their structure, including light small lifting equipment, elevators, and overhead monorail systems. Light small lifting equipment mainly includes lifting pulleys, lifting appliances, jacks, manual chain hoists, electric chain hoists, and ordinary winches. They are mostly small in size, light in weight, and easy to use. Except for electric chain hoists, most of them are driven by manpower and are suitable for occasions where the work is not heavy.
