For hand pulled hoists (hand pulled cranes or hand pulled pulley cranes), reducing maintenance work can mainly be carried out from two aspects: lifting prevention measures and daily maintenance. The following is an explanation from the perspective of improving lifting prevention measures on how to reduce the maintenance needs of chain hoists:

1、 Enhance lifting prevention measures

Ensure the qualifications of operators

Operators must undergo professional training and obtain relevant qualification certificates to ensure they are familiar with the use of chain hoists and safety operating procedures. This can avoid equipment damage and accidents caused by improper operation, thereby reducing maintenance needs.

Pre use inspection

Before each use, it is necessary to conduct a comprehensive inspection of the hand chain hoist, including the integrity of each component, the fastening of connecting parts, and the wear of pulleys and wire ropes. Once abnormalities or damages are found, they should be immediately stopped from use and repaired or replaced.

Reasonable selection and configuration

According to the requirements of the lifting task, choose the appropriate model and specifications of the chain hoist to ensure that its load-bearing capacity meets the requirements. At the same time, appropriate slings, lifting devices, and other accessories should be configured to ensure the safety and stability of the lifting process.

Comply with safety operating procedures

During the lifting process, safety operating procedures must be strictly followed, such as not overloading, not pulling or lifting diagonally, and not suspending heavy objects for a long time. These measures help reduce the load and wear of the chain hoist, extending its service life.

Set up safety warnings and alert areas

Set up clear safety warning signs and warning lines in the lifting operation area, and prohibit non operators from entering. This helps to reduce the occurrence of accidents and protect the chain hoist from damage caused by external factors.

Regular maintenance and upkeep

Although the main focus here is on preventive measures, regular maintenance and upkeep are also important means of reducing the need for repairs. Through regular inspections, cleaning, lubrication, and fastening maintenance work, potential problems can be identified and addressed in a timely manner, preventing small issues from escalating into major failures.

2、 Example of specific maintenance measures

Maintenance of pulleys and wire ropes: Regularly check the wear of pulleys and wire ropes, and replace them in a timely manner if there is excessive wear. Keep the pulleys and wire ropes clean and lubricated to reduce friction and wear.

Maintenance of transmission components: Check the lubrication and wear of transmission components (such as gears, chains, etc.) to ensure smooth transmission and no abnormal noise. If necessary, add or replace lubricating oil in a timely manner.

Maintenance of structural components: Check the integrity and fastening of structural components (such as hooks, chain boxes, etc.) to ensure that there are no cracks, deformations, or looseness. If there is any abnormality, it should be repaired or replaced in a timely manner.
