Structure and type matters of lifting tools.

A lifting tool is a material handling tool for lifting or lifting heavy objects. It is a tool that works intermittently and lifts heavy objects. Most lifting tools start a vertical or horizontal working stroke after the spreader picks up materials. After arriving at the destination, they unload, then empty travel to the pick-up location, complete a working cycle, and then carry out the second lifting. . Generally speaking, when lifting tools work, picking up materials, transporting and unloading are carried out in sequence, and the work of each corresponding mechanism is intermittent.

Various lifting tools have different uses and are very different in structure, but they all have a lifting mechanism to complete the basic action of adjustment. The material can be hung and adjusted by flexible parts such as wire ropes or lifting chains, or it can be lifted by screw rods or other rigid parts.

Lifting tools can be divided into light and small lifting equipment, hoists and overhead monorail systems according to different structures. Light and small lifting equipment mainly includes lifting pulleys, spreaders, jacks, 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 human power and are suitable for places where the work is not heavy.
