Electric hoists are generally installed on cranes. It is a special lifting equipment that improves labor efficiency and working conditions. The components of electric hoists are mainly divided into motors, electrical appliances, reducers, control boxes, wire ropes, conical motors, buttons. Transformation. So how many types of electric hoists are there? How to choose an electric hoist?
What is an electric hoist?
Electric hoists are a special type of lifting equipment, referred to as electric hoists. Installed on suspended I-beams, arc guides, cantilever lifting guides and fixed lifting points. It mainly completes heavy lifting, loading and unloading, equipment maintenance, cargo lifting and other tasks. It is an indispensable mechanical equipment for infrastructure projects such as construction, roads, metallurgy, and mining.
Types of electric hoists
Electric hoists are mainly divided into: chain electric hoists, wire rope electric hoists (explosion-proof hoists), anti-corrosion electric hoists, double-drum electric hoists, hoists, micro electric hoists, group electric hoists, and multi-functional hoists.

Selection of electric hoist
When selecting an electric hoist, you need to consider the following key factors:
Lifting capacity
Choose the lifting capacity of the electric hoist according to the actual weight of the hoisted items. Generally, you need to choose an electric hoist that is greater than or equal to the maximum load to ensure safety.
Lifting height
Lifting height refers to the maximum vertical distance that the electric hoist can lift. Select the appropriate lifting height according to actual needs.
Working environment
Consider the working environment where the electric hoist will be used, such as temperature, humidity, space size, whether there is explosive gas, etc. If the working environment is special, you need to choose special electric hoists such as explosion-proof and high-temperature resistant.
Operation mode
The electric hoist can be operated by manual, button, remote control or automatic control. Choosing the appropriate control mode depends on the needs of the operating site and the frequency of operation.
Span
Span refers to the lateral distance that the electric hoist can cover during operation. The choice of span needs to be determined according to the size of the working area.
Operation speed
When selecting an electric hoist, you also need to consider the lifting speed and travel speed. Higher speeds are suitable for frequent lifting of small objects, and lower speeds are suitable for heavier or more delicate lifting operations.
Power requirements
The power supply of the electric hoist is usually AC power, but there is also a DC power supply option. Select the appropriate power type and voltage according to the on-site power conditions.
Safety performance
Ensure that the selected electric hoist has the necessary safety features, such as overload protection, limit switches, emergency stop buttons, etc., to ensure safety during operation.
