Operational Test
- Select an appropriate load within the hoist's capacity.
- Lift the load to a designated height, observing the lift process.
- Ensure the hoist operates smoothly without jerking or stalling.
- Lower the load back to the ground carefully.
- Listen for grinding, squeaking, or rattling sounds.
- Feel for excessive vibrations in the hoist structure.
- Ensure all components are secure and properly aligned.
- Document any abnormal findings for further inspection.
- Operate the hoist to lift and lower the load.
- Evaluate the speed of ascent and descent.
- Check for consistent and immediate response to controls.
- Record any delays or irregularities in operation.
- Lift a load to a safe height.
- Activate the brake to hold the load in position.
- Ensure the load remains stationary without slipping.
- Release the brake to confirm smooth operation.
- Move the hoist to the upper limit and observe the switch activation.
- Repeat the process for the lower limit.
- Check that the hoist stops immediately upon switch activation.
- Document any discrepancies in limit switch function.
- Lift a known weight and observe the load indicator reading.
- Ensure the reading matches the actual weight of the load.
- Check for any inconsistencies during lifting and lowering.
- Replace or adjust the indicator if readings are incorrect.
- Lift a load to a safe height.
- Activate the emergency stop button.
- Ensure the hoist stops immediately without further movement.
- Reset the emergency stop and confirm normal operation resumes.
- Test each button on the remote individually.
- Check for responsiveness in lifting, lowering, and emergency stop.
- Ensure the signal reaches the hoist without delay.
- Replace batteries or repair remote if issues are found.
- Engage the manual override mechanism.
- Test the hoist operation using the manual controls.
- Ensure the hoist responds correctly without resistance.
- Document any issues for further evaluation.
- Attach a load equal to the hoist's maximum rated capacity.
- Lift the load to a predetermined height.
- Monitor for performance issues or overheating.
- Ensure all safety features function correctly during the test.
- Inspect connections visually for discoloration or damage.
- Listen for unusual sounds indicating electrical faults.
- Feel for excessive heat near electrical components.
- Document any signs of wear or potential failure.
- Operate the hoist with soft start engaged.
- Check for smooth acceleration and deceleration.
- Test variable speed settings for responsiveness.
- Document any discrepancies in feature performance.
- Watch the cable or chain during operation.
- Look for twists, knots, or binding issues.
- Test retraction by lowering the load completely.
