Before using a low net empty hand chain hoist for lifting and lowering operations, it is crucial to conduct a thorough inspection to ensure safety and operational efficiency. Below are the key points to check:

1. Structural Integrity

Chain and Hooks: Examine the load chain for signs of wear, corrosion, or deformation. Check that the hooks are not cracked, bent, or excessively worn. Ensure the safety latch is functional.

Body and Casing: Inspect the hoist body for cracks, dents, or any signs of damage. Ensure the casing is intact and securely fastened.

Hand Wheel and Handles: Verify that the hand wheel and handles are not damaged and rotate smoothly without excessive play or binding.

2. Brake System

Brake Functionality: Test the brake system to ensure it engages and disengages smoothly. The brake should hold the load securely when the hand chain is released.

Brake Pads/Shoes: Check for wear on brake pads or shoes. Replace if worn beyond the manufacturer's specified limits.

3. Gears and Bearings

Gear Teeth: Inspect the gear teeth for signs of wear, pitting, or damage. Ensure proper meshing between gears.

Bearing Operation: Check for smooth rotation of all moving parts. Listen for unusual noises (e.g., grinding, squeaking) that could indicate worn or damaged bearings.

4. Chain Guide and Sprockets

Chain Alignment: Ensure the load chain runs smoothly over the sprockets and is properly aligned in the chain guide. Misalignment can cause premature wear or chain failure.

Sprocket Condition: Check sprockets for wear, cracks, or damage. Replace if worn or damaged.

5. Load Capacity and Markings

Load Rating: Verify that the hoist is rated for the intended load. Never exceed the rated capacity.

Safety Labels: Ensure all safety labels and markings (e.g., load capacity, serial number) are legible and intact.

6. Lubrication

Lubrication Points: Check that all moving parts (gears, bearings, chain, etc.) are properly lubricated according to the manufacturer's recommendations. Insufficient lubrication can lead to premature wear or failure.

7. Test Operation

Dry Run: Perform a dry run (no load) to test the hoist's operation. Check for smooth lifting, lowering, and braking. Listen for unusual noises or vibrations.

Load Test: If possible, perform a test lift with a load slightly below the rated capacity to verify proper operation under load.

8. Safety Devices

Overload Protection: If equipped, test the overload protection device to ensure it functions correctly.

Emergency Stop: Verify that the emergency stop mechanism (if applicable) is operational.

9. Environmental Conditions

Cleanliness: Ensure the hoist is free of debris, grease, or other contaminants that could interfere with operation.

Corrosion: Check for signs of corrosion, especially in marine or humid environments. Address any corrosion issues promptly.

10. Documentation and Maintenance Records

Maintenance Log: Review the maintenance log to ensure the hoist has been serviced according to schedule.

Inspection Certificates: Verify that the hoist has passed recent inspections and certifications (if required by local regulations).

11. Operator Training

Operator Competence: Ensure the operator is trained and familiar with the hoist's operation, safety procedures, and emergency protocols.

12. Attachment Points and Rigging

Sling and Rigging: If using slings or rigging with the hoist, inspect them for damage, wear, or improper connections. Ensure the rigging is rated for the load.

13. Clearance and Space

Headroom and Reach: Verify that there is adequate clearance for the load to be lifted and lowered without obstruction. Check for overhead hazards (e.g., pipes, beams).

14. Ground and Support

Anchor Points: Ensure the anchor point (e.g., beam, truss) is capable of supporting the load and is securely fastened.

Stability: Check that the hoist is mounted or suspended securely to prevent tipping or shifting during operation.
