2 Introduction These 10 questions are for you to use to help get ready for the load chart and rigging part of the CraneSafe Level A Certification assessment for Mobile Hydraulic 80 Tonnes & Under. The questions on your assessment will be different from these but will be presented in the same format as these questions. With the questions are the answers with the relevant load charts. The answers explain how we arrived at the correct answer and you can use this to help work through any questions you may have gotten incorrect. We have not included all of the charts for this crane - but everything you need to answer the questions is included. You do not need the crane manual or full load chart package to answer the questions. The crane industry in BC has stated that operators must get a minimum of 7 out of 10 questions right on the load chart and rigging part of the assessment to be competent.

29 Answer Key 1. Answer: 26,410 pounds Net Capacity = Gross capacity minus load handling devices Determining Gross Capacity: A radius of 27 ft. is between values listed in the load chart Operation note # 10 applies to determine gross capacity. The next longer radius is 30 ft with a gross capacity of 27,900 lbs with 100 ft of main boom extended. Deductions from Gross Capacity 60 ton block 996 lbs 6.2 hook ball 289 lbs Auxiliary lifing sheave 110 lbs Rigging 95 lbs Total Deductions 1,490 lbs Gross Capacity is 27,900 pounds. Net Capacity is 27,900 1,490 = 26,410 pounds. 2. Answer: 3,010 pounds The main boom is between values list at boom length of 115 ft. Operation note # 9 applies to determine gross capacity. Must check the capacities at 110 ft and 120 ft length and use the lesser of the two capacities at a 90 ft radius. Gross capacity at a 90 ft radius and 110 ft of main boom = 4,500 lbs Gross capacity at a 90 ft radius and 120 ft of main boom = 4,800 lbs Deductions from Gross Capacity 60 ton block 996 lbs 6.2 hook ball 289 lbs Auxiliary lifing sheave 110 lbs Rigging 95 lbs Total Deductions 1,490 lbs Gross Capacity is 4,500 pounds. Net Capacity is 4,500 1,490 = 3,010 pounds. CraneSafe Certification + Fulford Harbour Group AK2

30 3. Answer: 7,910 pounds The main boom angle is between values listed for 130 feet of main boom. Operation note #20 applies to determine gross capacity. The next lower boom angle is 59.5 degrees with a gross capacity of 9,400 lbs. Deductions from Gross Capacity 60 ton block 996 lbs 6.2 hook ball 289 lbs Auxiliary lifing sheave 110 lbs Rigging 95 lbs Total Deductions 1,490 lbs Gross Capacity is 9,400 pounds. Net Capacity is 9,400 1,490 = 7,910 pounds. 4. Answer: 45 feet Gross Load on Crane Load weight 10,300 lbs 60 ton ball 996 lbs 6.2 ton hook ball 289 lbs Auxiliary lifting sheave 110 lbs Rigging 95 lbs 11,790 lbs With outriggers at 18 ½ mid extended position in the question, the capacity is determined using the capacity chart for the outrigger configuration in the question. Maximum radius is 45 feet. 5. Answer: 64.9 feet Gross Load Load weight Hook ball Rigging 5,000 lbs 289 lbs 50 lbs 5,339 lbs Go to the jib capacity chart for foot boom length plus 32.5 foot jib. Follow down the 25 degree tilt chart until a capacity that is equal to or greater than the gross load of 5,339 lbs. At a radius of 71.2 feet, the capacity of the jib is 5,300 lbs which is lower than the gross load on the crane. At a radius of 64.9 feet, the capacity of the jib is 5,900 lbs.

31 6. Answer: 70 degrees Deductions from Gross Capacity Load weight 2,800 lbs 6.2 ton hook ball 289 lbs Rigging 60 lbs Total Gross Load 3,149 lbs Go to the capacity chart for 110 feet of main boom plus 58.1 foot jib at a 45 degree tilt. Follow down the W column until a capacity that is equal to or greater than the gross load on the crane of 3,149 lbs. At 70 degrees the crane s capacity is 3,200 lbs. 7. Answer: 45 degree tilt Check all three offsets for the crane configuration in the question. Determine the maximum radius for the gross load on the crane 2,249 lbs: 3.5 degree tilt at a 95.8 foot radius capacity 2,300 lbs 25 degree tilt at a 106 foot radius capacity 2,400 lbs 45 degreet tilt at a 109 foot radius capacity 2,300 lbs 8. Answer: 18,525 pounds To determin gross capacity: because the radius is between values listed, you must go to the next longer radius 25 feet because the foom length is between values listed, you must check the capacity of the next longer boom length and the next shorter boom length at the 25 foot radius and take the lesser of the two capacities foot of boom at a 25 foot radius = 21,000 lbs 61.8 feet of boom at a 25 foot radius = 20,000 lbs Deductions from Gross Capacity 60 ton block 996 lbs 6.2 ton hook ball 289 lbs Auxiliary lifting sheave 110 lbs Rigging 80 lbs Total Deductions 1,475 lbs Gross Capacity is 20,000 pounds. Maximum pick and carry is 20,000 1,475 = 18,525 pounds. CraneSafe Certification + Fulford Harbour Group AK4

32 9. Answer: 3/4 inch The sling is at an angle of 55 degrees, so go to the next smaller angle of 45 degrees. The sling is in a double basket hitch configuration, so multiply the capacities by 2. 5/8 : 10,000 x 2 = 20,000 lbs (too small) 3/4 : 14,400 x 2 = 28,800 lbs 10. Answer: 7/8 inch The sling is at an angle of 35 degrees, so go to the next smaller angle of 30 degrees. The sling is in a choked configuration, so multiply the capacities by 3/4 (0.75). 3/4 : 10,200 x.75 = 7,650 lbs (too small) 7/8 : 13,750 x.75 = 10,312 lbs CraneSafe Certification + Fulford Harbour Group AK5
