6.3.2 Conducting the investigation
The inspection must be performed in compliance with the DGUV 309-001 principle (BGG 905) and with the valid
national standards and regulations. At least the following must be inspected:
• Testing of all functions without a load.
• Inspection of all safety devices.
• Load test with a test load = 1.25 x nominal load.
In essence this test serves to test the supporting structure and the brake.
Proceed with the greatest caution when performing the test. Keep the load always
near to the ground, and commence the following operation only if the swings from the
previous operation have subsided. Document any deformations and swings.
• Load test with a test load = 1.1 x nominal load (dynamic load)
Test all possibilities for proper operation as intended. Perform the dynamic test with the overlap of the possible
operational movements, with the maximum working speed. The hoist must be capable of lifting 1.1 times the
nominal load without a change to the setting of the slipping clutch.
• Examine the behaviour of the hoist / crane if used incorrectly.
• Test all functions at 1.1 x the nominal load.
• Actuate all safety devices.
• Document the completion of the first use in the crane testing log.
• Record the date of the 1
st
repeated inspection with an inspection sticker and/or with an entry to the crane
inspection log.
After the completion of the first use the hoist or the crane can be used properly as
intended.
