To extend the service life of a lever chain hoist, regular and systematic maintenance is essential. Here’s a structured approach to maintaining the hoist effectively:

1. Daily Maintenance

Visual Inspection:

Check for any visible damage, such as cracks, dents, or deformation on the body, hooks, and chain.

Inspect the hooks for intact safety latches and ensure they are not bent or cracked.

Verify that the lifting chain is free from kinks, twists, or excessive wear.

Cleaning:

Remove dirt, dust, and debris from the hoist using a soft brush or cloth.

Pay special attention to the chain and gears, ensuring they are free from contaminants that could cause wear.

Lubrication Check:

Ensure that all moving parts, such as gears, bearings, and chain links, are adequately lubricated.

If lubrication appears insufficient, apply a light coat of the manufacturer-recommended lubricant.

2. Weekly Maintenance

Detailed Inspection:

Conduct a more thorough inspection of the hoist, focusing on components that experience high stress during operation, such as the brake system, load chain, and hooks.

Test the brake by lifting a small load slightly and then releasing the lever. The load should remain suspended without slipping.

Lubrication:

Apply lubricant to all moving parts, following the manufacturer's recommendations for the type and frequency of lubrication.

Pay particular attention to the chain, ensuring it is well-lubricated to reduce friction and wear.

Function Test:

Perform a function test by lifting and lowering a light load to ensure the hoist operates smoothly and without any unusual noises or vibrations.

3. Monthly Maintenance

Comprehensive Inspection:

Disassemble the hoist (if possible) to inspect internal components for wear or damage.

Check the gears, bearings, and other internal parts for signs of excessive wear, corrosion, or damage.

Load Chain Inspection:

Examine the load chain for signs of elongation, corrosion, or damage.

Replace the chain if it shows signs of significant wear or damage, as a damaged chain can compromise the safety and performance of the hoist.

Brake System Adjustment:

Adjust the brake system if necessary to ensure it provides sufficient stopping power.

Follow the manufacturer's instructions for brake adjustment, as improper adjustment can lead to brake failure.

4. Annual Maintenance

Professional Inspection:

Have the hoist inspected by a qualified professional who can perform a more detailed and thorough assessment of its condition.

The professional can identify potential issues that may not be apparent during routine inspections and recommend necessary repairs or replacements.

Replacement of Worn Parts:

Replace any worn or damaged parts identified during the annual inspection.

This may include components such as gears, bearings, chains, hooks, and brake systems.

Load Testing:

Perform a load test to verify that the hoist can still safely lift its rated capacity.

Follow the manufacturer's instructions for load testing, and ensure the test is conducted in a safe and controlled environment.

5. Storage and Handling

Proper Storage:

Store the hoist in a clean, dry location away from moisture, corrosive substances, and extreme temperatures.

Hang the hoist from a sturdy support to prevent the chain from becoming tangled or damaged.

Avoid Overloading:

Never exceed the rated capacity of the hoist, as overloading can cause significant damage to the equipment and pose a safety risk.

Gentle Handling:

Handle the hoist with care to avoid dropping or impacting it, which can cause internal damage or deformation.

6. Additional Maintenance Tips

Keep Records:

Maintain detailed records of all maintenance activities, including inspections, lubrication, repairs, and replacements.

These records can help track the hoist's condition over time and identify patterns of wear or failure.

Follow Manufacturer's Recommendations:

Always follow the manufacturer's recommendations for maintenance, including the type and frequency of lubrication, inspection intervals, and replacement parts.

Train Operators:

Ensure that all operators receive proper training on the safe use and maintenance of the lever chain hoist.

Operators should be familiar with the hoist's limitations and know how to identify potential issues that may require maintenance or repair.
