Electric chain hoist maintenance guide

The load-bearing electric chain hoist with trolley is an important part of the chain hoist and also the core load-bearing component. Lifting Machinery found that among the electric chain hoists being repaired, technicians identified that a large part of them were caused by the user not lubricating the hoist chain for a long time. Lubricating the load-bearing chain is a very important part of chain hoist chain maintenance. Applying the load-bearing chain regularly can not only reduce the noise caused by friction, but also extend the service life of the hot sale electric chain hoist with trolley for sale.

Understand the role of lubricants
1. Lubrication: Chain lubrication can reduce factory supply electric chain hoist with trolley price friction, improve the safety factor, and turn dry friction into wet friction;
2. Cooling effect to prevent the chain from rusting;
3. The lubricating grease itself has no corrosive effect on the chain and plays a role in isolating the corrosion of moisture and other impurities in the air. At the same time, it can also neutralize the corrosion of the chain caused by excessive acid and alkali;
4. Damping effect: Friction and vibration are inevitable during the lifting process. However, due to the existence of the lubricating oil film, the mechanical energy generated by the vibration is absorbed by the oil film and converted into internal friction heat, thereby eliminating the vibration energy of the machine through the friction of the liquid. , so that the equipment runs smoothly;
5. Cleaning effect: The friction particles generated during the friction process of the chain, as well as impurities in the surrounding environment, can accelerate the wear and tear of the electric chain hoist with trolley manufacturer, and the lubricating oil can flush them out of the body;
6. Sealing effect: Lubricating oil not only lubricates and reduces friction, but also enhances sealing. Lubricating grease also has a special role in forming a seal, which can prevent water vapor or other dust and impurities from entering;

How to use lubricants correctly during maintenance
1. The frequency of electric chain hoist maintenance should be determined according to the user’s actual usage.
Old gourds are badly worn and have a lot of impurities, so they need more maintenance. New gourds have little or no wear and impurities and only require routine maintenance. Routine treatment means wiping it clean with a dry cloth after use and placing it in a dry and ventilated place.
2. If the oil in the gear box of the electric chain hoist reaches 500 hours from the beginning of operation, please check whether the amount of lubricating oil is sufficient. Check the lubricating oil regularly in the third month after that. If it is insufficient, add more oil.
3. The chain of the electric chain hoist should be lubricated with engine oil. In factories with high dust, please apply engine oil, and foreign matter in the chain and the limit guide groove group should be removed regularly to ensure smooth operation of the chain.
When the electric chain hoist is not used for a long time, it should be rust-proofed, cleaned and maintained, and run up and down for 1-3 minutes to maintain its performance.
4. To maintain the electric chain hoist chain, please lubricate the chain with engine oil. Please apply engine oil in high-dust factories, and regularly remove foreign matter in the chain and limit guide groove group to ensure smooth operation of the chain.
Lubricating oil with guaranteed quality and quantity should be selected. You can consult the original electric chain hoist with trolley supplier manufacturer for the brand type of lubricating oil.
5. When using an electric chain hoist outdoors, rainproof equipment should be installed on the hoist to prevent rainwater from infiltrating into the equipment. Always keep the parts of the electric chain hoist dry. Please move the hoist away from humid areas, high temperature areas, and chemical areas immediately after each operation to maintain the performance of the hoist.
