The maintenance and upkeep of low net gourd is the key to ensuring its long-term stable operation, improving work efficiency, and extending its service life. The following provides a detailed introduction on how to properly maintain and care for low net empty gourd from the aspects of maintenance methods, precautions, and specific component maintenance guidelines:

Maintenance and upkeep methods

Component inspection

Before each use, check whether all components of the manual hoist are intact, including whether they are damaged or loose. Special attention should be paid to checking key components such as brakes, lifting chains, pulleys, and transmission devices to ensure that all rotating parts of the chain hoist rotate flexibly and that fasteners are not loose.

brake inspection

Ensure that the brake can work properly and smoothly start and stop the hoist after pulling the handle. The friction surface of the brake must be kept clean to prevent brake failure. Regularly inspect the friction surface of the brake to ensure that there are no oil stains or impurities, and regularly check the braking performance to prevent brake failure from causing the lifting object to fall off.

Chain inspection

Check the tightness and wear of the lifting chain. The chain should maintain appropriate tension to avoid being too tight or too loose. At the same time, check the chain for corrosion, deformation, and damage to ensure its cleanliness and prevent any debris from sticking to it.

Oil lubrication

The various components of the manual hoist need to be regularly oiled to reduce wear and extend service life. It is recommended to apply engine oil or lubricant once a month and clean the existing oil before applying to avoid contaminating the new oil.

Cleaning and maintenance

During use, manual hoists may accumulate dust, mud, and other debris. Therefore, it is necessary to clean the manual hoist once a month, especially the surfaces of running components such as gears and chains. Clean it thoroughly before applying oil to keep the gourd clean and lubricated.

Maintenance precautions

Storage environment

Hand pulled haws should be stored in a dry and ventilated place, avoiding damp environments to prevent mold growth. When not in use for a long time, appropriate protection and proper storage should be taken.

Limitations

Lifting heavy objects cannot exceed the lifting capacity specified by the chain hoist. If the lifting chain twists and knots, it cannot be used anymore. It is strictly prohibited to retract the lower hook onto the lifting chain to lift goods.

operation safety

When lifting heavy objects, it is strictly prohibited for personnel to do any work or walk under the heavy objects. If there is danger, please leave immediately. When the hand zipper does not move, it cannot be pulled forcefully, nor can additional personnel pull it. It is necessary to stop using it immediately. It is not allowed to use power other than human labor to operate the hoist. During use, do not pull it too high or too low. Do not perform diagonal or horizontal pulling operations. It is strictly prohibited to use two or more chain hoists to lift goods at the same time, throw chain hoists, or use them to lift or lower passengers.

Specific component maintenance guide

hook

Regularly inspect the wear and deformation of the hook, and check for defects such as cracks, sharp angles, burrs, corrosion, warping, and twisting.

Gears and bearings

Regularly check the rotation of gears and bearings to ensure flexibility, and lubricate them with butter if necessary.
