Before using an explosion-proof lever hoist for lifting and lowering operations, a comprehensive safety check is essential to ensure its reliable performance and prevent accidents in potentially explosive environments. Here are the key aspects to inspect:

1. Exterior and Structural Integrity

Visual Inspection: Check for any visible damage, cracks, or corrosion on the hoist body, handle, and lifting chain. Ensure all components are intact and securely attached.

Load Chain: Examine the chain for wear, elongation, or twisted links. Replace any damaged or worn chain immediately.

2. Explosion-Proof Components

Enclosure Integrity: Verify that the explosion-proof enclosure is undamaged and properly sealed. Check for any signs of tampering or loose fittings that could compromise its ability to contain an internal explosion.

Certification Labels: Ensure the hoist bears valid explosion-proof certification labels (e.g., ATEX, IECEx) and that they match the intended use environment.

3. Mechanical Functionality

Lever Operation: Test the lever for smooth operation. It should move freely without excessive resistance or sticking.

Brake System: Check the brake for proper engagement and disengagement. The brake should hold the load securely when the lever is released.

Load Hook: Inspect the hook for deformities, cracks, or wear. Ensure the safety latch is functioning correctly and is free of obstructions.

4. Safety Devices

Overload Protection: Confirm that the hoist is equipped with an overload protection mechanism and that it is functioning properly.

Limit Switches (if applicable): Test any limit switches to ensure they activate at the correct points, preventing over-travel.

5. Lubrication and Maintenance

Lubrication: Check that all moving parts are adequately lubricated according to the manufacturer’s recommendations.

Maintenance Records: Review recent maintenance logs to ensure the hoist has been serviced regularly and any issues addressed.

6. Environmental Considerations

Operating Conditions: Ensure the hoist is suitable for the specific explosive environment (e.g., Zone 1, Zone 2) and that it is rated for the temperature class of the area.

Contamination: Check for any foreign objects or contaminants that could interfere with the hoist’s operation or compromise its explosion-proof rating.

7. Documentation and Training

User Manual: Review the user manual for any specific pre-use checks or procedures required by the manufacturer.

Operator Training: Ensure the operator is trained in the proper use of the explosion-proof lever hoist and is aware of safety protocols.

8. Test Lift

Pre-Use Test: Perform a test lift with a load significantly lighter than the hoist’s rated capacity to verify smooth operation and proper functioning of all components.
