After the installation of running chain hoists, the following inspection and testing methods can be adopted to ensure their safe and efficient operation:

1. Compliance Verification

Registration and Inspection: Confirm that the chain hoist has been registered with the relevant regulatory authorities and has undergone necessary inspections.

Documentation Review: Check that all necessary documentation, such as installation records, maintenance logs, and safety certificates, are complete and up-to-date.

2. Visual Inspection

Structural Integrity: Inspect the chain hoist for any signs of damage, deformation, or corrosion. Pay particular attention to the chain, hooks, gears, and bearings.

Fastenings and Connections: Check that all bolts, nuts, and other fastenings are tight and secure. Ensure that electrical connections are properly insulated and free from damage.

3. Functional Testing

Empty Load Test: Conduct an empty load test to verify that the chain hoist operates smoothly and that all mechanisms function correctly. Check for any abnormal noises, vibrations, or heat generation.

Rated Load Test: Perform a rated load test to ensure that the chain hoist can lift and lower the specified load without any issues. Monitor the performance of the motor, brakes, and other components during the test.

Overload Test (if applicable): In some cases, it may be necessary to conduct an overload test to verify the hoist's ability to withstand loads exceeding its rated capacity. This test should be carried out under controlled conditions and in accordance with relevant safety standards.

4. Safety Device Testing

Brake Testing: Test the braking system to ensure that it engages and disengages properly and that the hoist can be stopped safely at any point during operation.

Limit Switch Testing: Verify that the limit switches function correctly, preventing the hoist from exceeding its maximum lift height or travel distance.

Emergency Stop Testing: Test the emergency stop button to ensure that it cuts off power to the hoist immediately when pressed.

5. Load Chain Inspection

Chain Wear and Elongation: Measure the chain for wear and elongation using appropriate tools. Replace the chain if it exceeds the manufacturer's recommended limits.

Chain Lubrication: Check that the chain is properly lubricated to reduce friction and wear. Apply lubricant as needed.

6. Electrical System Inspection

Wiring and Connections: Inspect the electrical wiring and connections for damage, loose connections, or signs of overheating.

Motor and Controller Testing: Test the motor and controller to ensure that they operate correctly and that the hoist responds accurately to control signals.
