1. Visual Inspection
Check for any visible defects (cracks, dents, misalignments).
Ensure all components (suction cups, handles, valves, hoses) are properly assembled.
Verify labels, branding, and safety markings are correctly applied.
2. Functional Testing
Suction Test:
Apply the lifter to a clean, flat glass surface.
Activate the vacuum mechanism (manual or pump-based).
Verify that suction is strong and consistent (no air leaks).
Measure vacuum pressure (if applicable) to ensure it meets specifications.
Load Test:
Test with the maximum rated load (or slightly above, if required by standards).
Lift and hold for a specified duration (e.g., 10-15 minutes) to ensure stability.
Check for any loss of suction or mechanical failure.
Release Test:
Ensure the release mechanism works smoothly without sudden drops.
