Enter your name and student number in the spaces below. Name: Student number: Each question has several answers, only one of which is correct. Select your answer by typing # in the box. When complete, save the file using the same name. Then use the upload facility to return it for marking. 1. The purpose of a proof load/force test is to: Establish the WLL of the item under test # Confirms the item is capable of sustaining the applied load at the time of the test To destroy items which have defects or too high a WLL To meet the suppliers duties under the Supply of Machinery (Safety) Regulations 2. The working load limit (WLL) should: # Be set at the limit of proportionality Be just below the calculated breaking load #  Not exceed 50% of the elastic limit Exceed the elastic limit by 50% 3. The proof load/force should:  Always be the same as the manufacturers proof force Not exceed 50% of the elastic limit Be just below the calculated breaking load # Not exceed the elastic limit 4. LOLER leaves it to the discretion of whom to decide if any tests are required: # The competent person The user The HSE The LEEA 5. LEEA Technical Requirements state that test machines must have a minimum accuracy of: ±10% ±5% # ±2% ±1.5% 6. When using weights to test lifting appliances, the accuracy of the applied load should be: ±10% ±5% # ±2% ±1.5%    2 © Lifting Equipment Engineers Association 2012 - training\1-7e7e0000  7. Liquid penetration crack detection can: Reveal faults beneath the surface of the material # Reveal the position of cracks only Reveal the position of blowholes in the material Reveal the depth of cracks 8. For marking material with a diameter of 20mm, the size of stamps used should be: 3mm 4mm # 4.5mm 6mm 9. BS EN 13411-3 calls for the verification of: The finished wire rope sling by testing it to destruction The wire rope only by a fatigue test # The ferrule termination by measurement and thorough examination  A wire rope sling by a proof load test 10. A light load test on a lifting machine should be: # Between 2% and 5% of the WLL Between 10% and 15% of the WLL Between 15% and 25% of the WLL Between 25% and 50% of the WLL 11. A Brinell hardness test is done by: Drilling the material and measuring the force required to push the drill  A fatigue test  A pendulum swinging down from a specified height and hitting the test piece # Pressing a hardened steel ball into the material and measuring the indentation 12. When preparing to examine a grade 8/T chain sling for examination it should first be: Stripped down to its component parts if the design is such that the load bearing surfaces cannot be seen Soaked in a dilute acid based cleaning agent # Cleaned by wire brushing Have the paint burnt off with a blow torch 13. To measure wear an examiner should: Have available a magnifying glass # Be able to judge when wear has reached its maximum  Ask a qualified engineer to make the measurements #  Have available rule, vernier, micrometer or gauges as appropriate 14. When examining a chain sling that has been in service, the maximum wear permissible is: # 8% of diameter 6% of diameter 5% of diameter No wear permitted 15. A hook on a grade 40 chain sling is found to have opened by 15%, the correct action to take is: Have a blacksmith close the hook # Send a copy of the report to the HSE Take no action as this is within the permitted limit Replace the complete chain sling    3 © Lifting Equipment Engineers Association 2012 - training\1-7e7e0000  16. When examining an eyebolt that has been in service the maximum permissible wear on the threads is: 10% # 8% 5% #  No wear permitted 17. When examining a lifting beam with top shackle suspension and single leg bottom chain slings shackled each end: #  The assembly should be stripped down to its separate component items # Examined as a complete assembly The end of the shackle pin threads should be welded to ensure they cannot be removed It should be painted with black and yellow stripes to comply with the European Machinery Directive 18. If an item of lifting gear is found to have a defect which affects its safety, the examiner must by law: # Ensure a copy of the report is sent to the HSE Scrap the item by cutting it into two or more pieces Refuse to issue a report Is not required to take any action other than inform the owner/user 19. If a lifting appliance is found to have a defect which affects its safety, the examiner must by law: # Ensure a copy of the report is sent to the HSE  Allow the user 28 days to make the repairs Issue a written warning to the operator Inform his manager 20. When examining an item of lifting equipment that has been in service, the examiner: Is responsible for affixing the CE mark # Should ask to see a current test certificate/EC Declaration of Conformity Stamp it with the date of the examination If marked, remove the CE mark as this only applies to new equipment Marking  Answers still shown in black were correct  Answers now shown in red were incorrect – the correct answers are shown in blue Result 80%
