Methods to Improve the Efficiency of Hand Chain Hoists

I. Standard Operating Procedures

Correct Installation and Force Control

Installation Point Selection: Ensure that the hook is securely connected to the object being lifted. Do not use worn or deformed hooks. The hook opening should face outward to prevent lateral force from causing slippage.

Force Direction: Keep the chain vertical to avoid slanting or hard pulling. When the slant angle exceeds 5°, adjust the lifting position or use a swivel pulley to prevent chain jamming or breakage.

Load Limitation: Strictly follow the rated load and prohibit overloading. Overloading will cause chain deformation, accelerated gear wear, and even trigger safety accidents.

Operation Technique Optimization

Uniform Pulling: Avoid rapid, forceful pulling or sudden release to prevent chain knotting or equipment impact damage.

Hand Cooperation: Hold the chain with one hand and support the brake with the other to ensure smooth operation. When lowering the heavy object, slowly release the brake to control the descent speed.

II. Regular Maintenance and Care

Cleaning and Lubrication

Clean the chain, gears, and casing after each use to remove dust, oil, and debris.

Regularly apply special lubricating oil (such as lithium-based grease) to the meshing points of the chain and gears to reduce wear and noise.

Component Inspection and Replacement

Chain: Check if the chain links are cracked, deformed, or worn beyond 10% of the original diameter. Replace them promptly.

Brake: Test the braking performance to ensure reliable stopping when lowering the heavy object.

Hook: Check for cracks, torsional deformation. Replace immediately if necessary.

Casing: Check for cracks or deformation. Prevent internal parts from getting damp or foreign objects from entering.

Storage Management

Store in a dry, ventilated room to avoid dampness and corrosive environments.

III. Environmental Adaptation and Safety Measures

Work Environment Optimization

Space Requirements: Ensure there are no obstructions within the lifting height and that the operator has sufficient space for movement.

Ground Conditions: When using on soft or uneven ground, reinforce support points to prevent equipment from tipping over.

Temperature Range: Avoid using in environments outside the range of -40°C to +50°C to prevent material performance degradation. Safety protection

Wear protective equipment such as safety helmets and gloves to prevent injuries caused by falling heavy objects or broken chains.

Set up warning lines in the lifting area and prohibit irrelevant personnel from entering.
