Electric hoist trolleys are inspected regularly to ensure safe operation. Here are some of the key inspection procedures:
Visual Inspection:
Examine the overall condition of the trolley, including the structure, wheels, and load-bearing components for any signs of wear, damage, or deformation.
Check the electrical connections, wiring, and control panels for any loose, frayed, or damaged components.
Inspect the hoist and hook for proper operation, lubrication, and any visible defects.
Functional Testing:
Operate the trolley through its full range of motion, including traversing, raising, and lowering the load, to ensure all functions are working correctly.
Test the emergency stop and other safety features to verify their proper operation.
Confirm that the load-limiting and overload protection systems are functioning as intended.
Load Testing:
Conduct a static load test by lifting a test weight equal to the rated capacity of the trolley and holding it for a specified duration.
Perform a dynamic load test by lifting, traversing, and lowering the test weight throughout the trolley's range of motion.
Measure and record any deformation or deflection of the trolley structure and components during the load tests.
Brake Inspection:
Examine the condition and operation of the trolley's braking system, including the brake pads, linings, and mechanisms.
Ensure the brakes can hold the load securely and that the brake release and engagement functions properly.
Electrical Inspection:
Check the electrical controls, limit switches, electric hoist trolley and safety devices for proper operation and any signs of deterioration.
Measure the insulation resistance of the electrical components to ensure they meet the minimum requirements.
Verify that all grounding connections are secure and effective.
Documentation and Record-Keeping:
Maintain detailed inspection records, including dates, findings, and any necessary repairs or adjustments.
Ensure that the trolley's load rating, inspection, and maintenance history are clearly documented and accessible.
These comprehensive inspection procedures help to identify any potential issues or defects in the electric hoist trolley, allowing for timely maintenance and repairs to maintain safe and reliable operation.
