Step 1: Perform a visual inspection
Visual inspections may not sound technical, but they are an essential aspect of safe and proper crane operation. Before using a crane, always perform a preliminary visual inspection. Look for any apparent damage, such as cracks in the structure or deformities. Check the wire ropes, chains, slings, hooks, and rigging components for signs of wear and tear, such as cuts, corrosion, or broken wires. Check the hoist motor and gearbox for any signs of oil or lubricant leaks that could cause equipment failure. Always check the electrical components of the crane, motors, and limit switches for proper functioning. Document any defects on a daily safe use checklist and take appropriate action to repair or replace damaged parts.
Step 2: Review the Crane History
Crane manufacturers document all relevant information on the manufacturer's tag in the electrical control box. Inspect the tag to ensure that the crane is rated for the job and work environment. The information on the tag includes the rated load capacity, span length, hoisting speed, trolley speed, and bridge speed. Check the inspection and maintenance schedule to see if the crane has undergone a recent repair or modification. Reviewing the crane history will help you detect any warning signs and improve overall crane safety.
Step 3: Test the crane's safety features
Safety features on the overhead crane ensure a safer work environment for workers and maintain proper functioning of the machinery. Perform various functional tests, such as testing brakes, limit switches, hoist controls, and overload protection devices. Test the emergency stop switch and ensure that they are working. Disable the hoist motor and check for proper operation of the controls. Test the safety sensors, lights, and alarms for proper functioning.
Step 4: Inspect the Load chains
Inspect the load chain for proper wear, cracks, and deformation. Check the chain lubrication and ensure that the load chain is not exceeding its maximum limit. A load chain that exceeds its maximum limit can cause equipment failure and accidents. Ensure that the chain is securely attached to the crane hook, and the hook-safety latch is closed tightly. Document the inspection results and take appropriate actions to repair or replace any damage that you find.
Step 5: Document the inspection results
An essential aspect of any inspection is keeping detailed and comprehensive records of safety inspections. Documentation serves as evidence of compliance and provides a list of ongoing maintenance requirements, including any defects or issues that require immediate attention. Documentation will assist you in keeping the crane and hoist in good working order and ensure the safety of your workers.
