Before using a European steel wire rope electric hoist for lifting and lowering operations, a comprehensive inspection is crucial to ensure safety and optimal performance. The following is a structured checklist of key areas to inspect:

1. Mechanical Components

Wire Rope:

Check for fraying, kinks, corrosion, or broken strands. Replace if any damage is found, as it compromises load-bearing capacity.

Ensure proper winding on the drum (no overlapping or jamming).

Hook:

Inspect for cr, deformation, or excessive wear. The hook should rotate freely without binding.

Verify the safety latch is intact and functional.

Brake System:

Test the emergency and holding brakes for responsiveness. The hoist should stop immediately when the control is released.

Check for oil leaks or unusual noises during braking.

Limit Switches:

Test upper and lower limit switches to ensure they activate at the correct positions, preventing overtravel.

Adjust if necessary, but do not rely on them for routine stopping.

Drum and Sheaves:

Inspect the drum for cracks, grooves, or uneven wear.

Check sheaves for smooth rotation and proper alignment.

2. Electrical Systems

Power Supply:

Verify voltage and frequency match the hoist’s specifications.

Check for loose or damaged electrical connections.

Control Panel:

Inspect buttons, switches, and emergency stops for proper operation.

Ensure the remote control (if used) functions within the specified range (typically ≤15m) and has a secure connection.

Grounding:

Confirm the hoist is properly grounded to prevent electrical hazards.

3. Structural Integrity

Hoist Frame:

Check for cracks, bends, or corrosion in the frame or mounting brackets.

Ensure all bolts and fasteners are tightened to the manufacturer’s torque specifications.

Support Structure:

Inspect the mounting beam or trolley for stability and alignment.

Verify the load-bearing capacity of the support structure matches the hoist’s rating.

4. Safety Devices

Overload Protection:

Test the overload limiter to ensure it activates at the rated capacity (typically 110%–125% of the nominal load).

Check for error codes or alerts on the control panel.

Emergency Stop:

Press the emergency stop button to confirm immediate shutdown of all motions.

Anti-Drop Device:

For chain hoists, verify the chain anchor or anti-drop mechanism is functional.

5. Environmental Factors

Operating Area:

Clear the workspace of obstacles, personnel, and flammable materials.

Ensure adequate lighting for visibility.

Temperature and Humidity:

Confirm ambient conditions are within the hoist’s specified range (typically -25°C to +40°C).

Avoid use in corrosive or dusty environments unless the hoist is rated for such conditions.

6. Load-Specific Checks

Load Weight and Balance:

Verify the load does not exceed the hoist’s rated capacity.

Ensure the load is evenly distributed and securely attached with appropriate slings or grips.

Load Attachment:

Inspect slings, chains, or magnets for damage or wear.

Use protective padding at sharp edges to prevent wire rope or chain damage.

7. Operational Test

No-Load Test:

Run the hoist through a full up/down cycle without a load to check for smooth operation, unusual noises, or vibrations.

Test the trolley (if applicable) for lateral movement.

Light-Load Test:

Lift a load slightly below the rated capacity to confirm stability and brake performance.

8. Documentation and Labels

Certification and Inspection:

Verify the hoist has a valid inspection certificate and complies with local safety standards (e.g., CE, OSHA).

Check for warning labels (e.g., load capacity, emergency procedures) and ensure they are legible.

Maintenance Records:

Review recent maintenance logs to confirm the hoist has been serviced according to the manufacturer’s schedule.
