Hoist electric hoist is a common lifting tool, widely used in construction sites, factories, ports and other occasions. The following will introduce the lifting performance, working principle, scope of application and use precautions of different types of electric hoist.

First, lifting performance
Hoist electric hoist usually has a higher lifting capacity, can meet a variety of lifting needs. Its rated lifting weight is generally between 0.5 tons and 20 tons. In addition, the hoist electric hoist also has a higher lifting speed, can effectively improve the work efficiency.

Two, the working principle
Winch type electric hoist is mainly composed of motor, reducer, brake, gear drive, rope wheel. The motor drives the decelerator to rotate, and the decelerator converts the speed into torque through the gear drive, and then controls the rotation of the rope wheel through the brake, so that the rope pulls the lifting object. The working principle of the hoist electric hoist is relatively simple and easy to master.

3. Scope of application
Hoist type electric hoist is suitable for a variety of lifting occasions, such as construction site, factory workshop, port and so on. At the same time, because of its higher lifting capacity, it can also be used for large lifting projects.

Four, different models and characteristics
Hoist type electric hoist is usually classified according to its lifting capacity, use scenario and other factors, the following introduces several common models and their characteristics:

CD1 type hoist electric hoist: CD1 type hoist electric hoist is an ordinary type of hoist electric hoist, its lifting capacity is generally between 0.25~20 tons, suitable for factories, warehouses, docks and other lifting places. CD1 electric hoist is simple to use, the price is relatively cheap, is a common lifting equipment.

MD1 type hoist electric hoist: MD1 type hoist and CD1 type similar, but its use of hoist and motor are different. MD1 electric hoist lifting capacity is also generally between 0.25 and 20 tons, suitable for the same lifting place as CD1. Compared with CD1 type, MD1 type electric hoist has higher safety performance, lower noise and longer service life.

PA type mini hoist electric hoist: PA type electric hoist is suitable for light lifting, lifting capacity is generally between 100~1000kg. It usually adopts small motor and simple hoist structure, compact structure, small size, can be suspended in a simple crane or single beam crane use.

HB type manual monorail winch: HB type hoist electric hoist is a manually operated monorail winch, its lifting capacity is generally between 0.25 and 1 ton. HB type electric hoist small size, light weight, suitable for some inconvenient use of large lifting equipment occasions, such as mine, wharf, warehouse and so on.

Hoist electric hoist is a kind of lifting tool with excellent performance and wide range of application. In the process of use, it is necessary to comply with the relevant operating procedures to ensure its normal use, so as to improve work efficiency and ensure safe production.
