A well-maintained hoist chain guarantees durability, effective functionality and prevents accidents. It should be cleaned, lubricated or greased regularly, and inspections should be done before use and after 6 months for a thorough inspection. Unlike the usual chains, the chain hoist is used for overhead lifting and material handling for heavy equipment, and it supports suspended objects via hooks as it moves through internal sprockets without twisting or tangling. The effective functionality of the chain hoist is highly dependent on how they are maintained and how often. This blog provides a guide on how to maintain chain hoists, their functions and the importance of maintaining the chain hoist.
The functions of the chain hoist
- Lifting and lowering: It has an internal gear reduction system, which is used to raise and lower vertical weights.
- Load positioning: The chain hoist is used for aligning the upper anchor, the lifting chain and the lower hook for machinery components and vehicle engines.
- Force multiplication: The chain hoist converts a small pull force or low torque into high lifting capacity.
- Holding and locking: The chain hoist has an internal mechanical brake that locks the chain in place so that it does not fall.
- Pulling and dragging: It can be used to function horizontally to drag heavy objects.
The importance of maintaining a chain hoist
The hoist chain gradually wears off the more it is used over time. When not well-maintained, the chain can suddenly lose its ability to function effectively, increasing the chances of accidents. These are the reasons why the hoist chain should be regularly inspected and maintained;
- Worker safety: A well-maintained chain has lower chances of snapping off or breaking when handling heavy weights.
- Cost savings: Regular maintenance of the hoist chains prevents unexpected replacement of components, which significantly cuts on costs.
- Peak performance: A well-maintained hoist chain has a higher guarantee of effective functionality for a long period of time.
Minimized downtime: Regular maintenance of a hoist chain reduces the risk of unexpected equipment failure.
How to maintain a chain hoist
- The components of the chain hoist should be cleaned using a dry cloth or stiff brush to remove dirt and metal shavings from the frame and chain. Removing the first allows effective functionality by reducing metal wear and jamming.
- The chains should be lubricated by applying machine oil or the recommended lubricant so that it penetrates the internal mating surfaces. Lubricating the hoist chain prevents friction so that the chain does not undergo premature wear and prevents rust.
- The gears and the sprockets should be regularly greased for optimum functionality and prevention of wear. Ensure you apply the right amount of grease, as excess grease can attract gritty debris.
The components to inspect before using the chain hoist
The hoist chains should be inspected regularly before use and thoroughly checked every six months to prevent accidents and ensure effective functionality. Here is what needs to be thoroughly checked.
- The hooks
- The gears
- Load gears
- The electrical controls
Conclusion
The chain hoist has the capacity to last long and function effectively for a long period of time when well-maintained. Regular maintenance should be done as per schedule and not when the chain hoist starts to wear out or malfunction. Regular inspection is required to note any wear and broken gears; as such, regular maintenance should be conducted. Both the hoist chains and the chain binders should be well-maintained, and it is also important to buy them from trusted suppliers. Mr Jinder Atwal at Brampton Straps supplies chain binders that are of premium quality and guaranteed effective functionality for a long period of time.
FAQ’s
- How does a chain hoist function?
The chain hoist functions by using mechanical gears and pulleys; as the small hand chain is pulled, the internal gears multiply the force to raise the load.
- Can I use Libricant instead of grease for the chain hoist gears?
It is not recommended to replace the greasing of the gears with lubrication because the oil cannot penetrate the complex areas of the gears.
- Is a manual chain better than the electrical chain hoist?
Both the manual and the electrical chain hoist function effectively, and neither is better than the other; it only depends on the required need.
