After the initial installation of a low net empty handed chain hoist (which I interpret as a chain hoist installed in a low-ceiling or otherwise constrained environment, operated without additional support equipment like a trolley or bridge crane), several inspection items are required to ensure its safety, functionality, and compliance with relevant standards. Here are the key inspection items:

Structural Integrity:

Inspect the hoist frame, chain, and sprocket wheels for any damage, cracks, or wear.

Ensure all bolts, nuts, and other fasteners are securely tightened.

Chain Condition:

Check the chain for excessive wear, elongation, or damage.

Ensure the chain links are not twisted or bent.

Verify that the chain is properly lubricated.

Load Hook and Safety Latch:

Inspect the load hook for damage or deformation.

Ensure the safety latch is functioning correctly and securely locks the load.

Brakes and Limit Switches:

Test the brakes to ensure they can stop the load smoothly and without excessive slippage.

Verify that the limit switches are functioning correctly and prevent over-travel of the hoist.

Electrical System:

Inspect the electrical wiring and connections for any signs of damage or looseness.

Ensure the power supply is compatible with the hoist's specifications.

Test the emergency stop button to ensure it functions correctly.

Operating Mechanisms:

Check the chain wheel and sprocket for smooth operation and proper engagement.

Ensure the chain guide and tensioner are functioning correctly.

Verify that the hoist operates smoothly and without any abnormal noises or vibrations.

Compliance with Standards:

Ensure the hoist complies with relevant industry standards and regulations.

Check for any required certification or safety markings.

Environmental Considerations:

Assess the environment for any potential hazards that could affect the hoist's operation or safety.

Ensure the hoist is installed in a location that meets its operational and safety requirements.

User Training and Documentation:

Provide training to the users on the proper operation and maintenance of the hoist.

Ensure that all relevant documentation, such as manuals and safety instructions, are available and easily accessible.
