In factory workshops and construction sites, electric hoists are known as lifting wonders with "small size but great power". But what should you pay attention to when purchasing an electric hoist? And how to choose an electric hoist that meets your needs? This article will tell you.

Basic parameters

Lifting capacity: Select an appropriate lifting capacity based on the weight of the lifting object, ensuring that the electric hoist can meet the demand while leaving a safety margin.

Lifting height: Based on the actual working environment and lifting height requirements, select an appropriate lifting height. Common options include 6m, 9m, 12m, 18m, 24m, 30m, etc.

Lifting speed: Choose single-speed or dual-speed electric hoists according to operational needs. Single-speed is suitable for general working conditions, while dual-speed can be used when precise control is required.

Motor power and voltage: Select the appropriate motor power and voltage based on the on-site power supply conditions and usage environment to ensure the normal operation of the equipment.

Safety performance

Braking system: Choose electric hoists equipped with reliable braking systems, such as dual braking units and dual limit switches, to ensure timely stopping in emergency situations.

Safety factor: Pay attention to the breaking force of chains and steel wire ropes, ensuring that they meet the safety factor requirements of the rated load, such as the C1 standard requiring a 10-fold safety factor.

Safety device: Check whether there are anti-unhooking devices, overload protection devices, etc., to prevent the lifting objects from falling off or being used overload.

Use scenario adaptation

Working environment: Select the appropriate type of electric hoist according to the working environment. For example, the explosion-proof type is suitable for flammable and explosive places, the stainless steel type is suitable for humid environments, and the metallurgical type is suitable for high-temperature environments.

Operation frequency: For high-frequency and heavy-load operations, electric hoists are recommended. For low-frequency and heavy-load operations, chain blocks can be considered.

Automation requirements: If it is necessary to use it in conjunction with cranes and rails to achieve mobile handling, an electric hoist that supports automatic control should be selected.
