What lifting tools are commonly used in lifting operations?
Commonly used lifting tools and lifting appliances include jacks, inverted chains, snap rings, rope clips, hooks, hand hoists, winches, tackles and tackles, etc.
Pulleys and tackles are the more commonly used lifting tools in lifting and handling operations.
Jacks are widely used in lifting work. It can lift heavy machinery equipment with a small force, and can also correct the deviation of equipment installation and the deformation of components.
The snap ring is also known as armour removal, which is used for the connection between the rope buckle (jack rope, steel wire rope) and the rope buckle, or between the rope buckle and the component ring. It is a wider connection tool used in lifting operations.
Rope clips are mainly used for the temporary connection of wire ropes, the fixing of the back hand rope when the wire rope passes around the block, and the fixing of the wind rope rope head on the grille.
Hooks are divided into single and double hooks according to their different shapes. The hook is divided into a forged hook and a plate hook according to the forging method.
Component hoisting should prepare a special construction plan, which is also an integral part of the construction organization design.
Hand hoist is a lightweight and simple manual traction machine. It has the characteristics of compact structure, small size, light weight, convenient carrying, stable performance and so on.
The winch is a more commonly used manual traction tool. It is mainly used in remote areas where the lifting speed is not fast, there is no electric hoist, and there is no power supply.
The inverted chain is also called a chain hoist, which can be used to lift light components, tighten the cable wind rope of the grill rod, and tighten the bundled rope when the component or equipment is transported.
Lifting tools are mainly used to move items. After being equipped with a grab, they can handle loose materials such as coal, ore, and grain. When equipped with a bucket, they can lift liquid materials such as molten steel. Some lifting tools such as elevators can also be used to carry people. In some applications, lifting equipment is still the main working tool. For example, cranes for loading and unloading materials at ports and stations are the main working tools.
According to different structures, lifting tools can be divided into light and small lifting equipment, hoists and overhead monorail systems. Light and small lifting equipment mainly includes lifting tackles, spreaders, jacks, chain hoists, electric hoists and ordinary winches. Most of them are small in size, light in weight, and easy to use. Except for electric hoists, most of them are driven by manpower, suitable for occasions where the work is not heavy.
Use of lifting gear:
They can be used alone or in combination. Some light and small lifting equipment have a large lifting capacity, for example, the lifting capacity of hydraulic jacks has reached 750 tons. Mine elevators and hopper elevators are mainly used for vertical or near vertical lifting movements, and have fixed lifting routes. The overhead monorail system has lines formed by rigid hanging rails, which can transport materials to various parts of the plant, and can also be extended to the outside of the plant.
