Hand pulled hoist "in lifting equipment usually refers to a tool that uses hand zipper strips to lift heavy objects, rather than the literal meaning of" hand pulled hoist "(i.e. gourd products in handicrafts). Therefore, here we mainly discuss the modification and durability improvement methods of chain hoists (lifting equipment).

Transform the chain hoist

Although the structure of the chain hoist is relatively simple, caution is still needed in its modification to ensure safety and functionality. Here are some possible directions for renovation:

Electrification transformation:

Replace power source: Replace the original manual zipper mechanism with an electric motor to achieve electric lifting. This requires selecting a suitable electric motor and adjusting its installation position and transmission method.

Add control system: Install controllers, switches, sensors, etc. to achieve remote operation, speed regulation, overload protection, and other functions.

Add auxiliary devices:

Installing extension rods: In specific situations, extension rods can be designed and installed to increase operating distance or facilitate operation.

Add a display screen or indicator: used to display information such as weight, height, or speed, improving the accuracy and safety of operations.

Change appearance or material:

Coating or wrapping: Changing the color or wrapping protective layer of the chain hoist to meet the appearance or protection requirements of specific industries or environments.

Using special materials: In special environments that require corrosion resistance, high temperature resistance, or low temperature resistance, components made of special materials can be used for replacement.

Enhance load-bearing capacity:

Upgrade chains and hooks: Choose higher strength chains and hooks to enhance the load-bearing capacity of the chain hoist.

Optimizing structural design: By optimizing internal structural design, such as adding reinforcing ribs, improving pulleys and gears, the overall load-bearing performance can be improved.

Improve the durability of chain hoists

In order to extend the service life of the chain hoist and maintain its good performance, the following measures can be taken:

Regular maintenance and inspection:

Check the chain and hook: Ensure that the chain is not broken, twisted, or excessively worn, and the hook is free of cracks, burrs, or deformations.

Lubricate transmission components: Regularly apply lubricating oil to transmission components such as gears and bearings to reduce friction and wear.

Cleaning and maintenance: Keep the chain hoist clean and dry, and avoid damage from impurities such as oil and dust.

Correct use and operation:

Avoid overloading: Ensure that the chain hoist is used within the rated load range to avoid equipment damage caused by overloading.

Smooth operation: Maintain stability during operation to avoid sudden acceleration or deceleration that may cause impact.

Reasonable storage: Store the chain hoist in a dry, ventilated, and non corrosive environment, avoiding prolonged exposure to sunlight or humid conditions.

Replace worn parts:

Timely replacement: For worn or damaged components such as chains, hooks, pulleys, etc., they should be replaced in a timely manner to avoid affecting overall performance and service life.

Choose high-quality products:

Brand selection: Choose well-known brand chain hoist products, which usually have higher quality standards and more reliable after-sales service.
