Clevis
ABOVE: Test rig arrangement Assemble test rig as shown. Ensure hex legs are firmly screwed to bridge. Check that the clevis is fully engaged in the clevis adaptor within the tester body.
TESTING LADDER RESTRAINT HOOKS Follow the same setting up procedure as for s Safety Harness Eyebolt test above, and apply the load gradually until the required proof load of 2.5kN is reached or failure occurs. Observe if the hook withdraws from the structure or the test load cannot be achieved. This would be considered a failure and must be taken out of service.
