Which of the following is an accurate statement about luffing jibs? • A) It rotates 360 degrees independently from the boom • B) It raises and lowers independent from the boom • C) It extends and retracts with the boom • D) It is fixed at a 90-degree angle to the boom Answer: B) It raises and lowers independent from the boom Rationale: A luffing jib can be raised or lowered independently of the main boom, providing additional flexibility in crane operations. ________________________________________ 2. What is the weakest quadrant of a boom truck? • A) Rear • B) Side • C) Front • D) 45-degree angle Answer: C) Front Rationale: The front quadrant is typically the weakest for boom trucks due to the configuration and support structure design. ________________________________________ 3. What effect would be blocking up the ends of the tracks have on a crawler crane? • A) It would decrease capacity over the ends • B) It would increase capacity over the ends • C) It would have no effect on capacity • D) It would only affect side capacities Answer: B) It would increase capacity over the ends Rationale: Blocking the ends of tracks increases the stability footprint, thereby increasing capacity over the ends. ________________________________________ 4. The tipping axis of a crawler crane is: • A) Always at the center of the tracks • B) Always at the edge of the tracks • C) It depends if the idler or sprocket are offset from track rollers • D) Determined by the boom length Answer: C) It depends if the idler or sprocket are offset from track rollers Rationale: The tipping axis varies based on the specific design and whether components are offset from the track rollers. ________________________________________ 5. On a rough terrain crane, what is the strongest quadrant? • A) Front • B) Rear • C) Side • D) All quadrants are equal Answer: A) Front Rationale: Rough terrain cranes typically have their strongest lifting capacity over the front due to the stabilizer configuration. ________________________________________ 6. On a truck crane or all-terrain crane, the strongest quadrant is normally the: • A) Front • B) Rear • C) Side • D) Depends on outrigger extension Answer: B) Rear Rationale: Truck and all-terrain cranes typically have their strongest capacity over the rear due to the support structure design. ________________________________________ 7. On a boom truck, what is normally the strongest quadrant? • A) Front • B) Rear • C) Side • D) 45-degree angle Answer: B) Rear Rationale: Boom trucks typically have their strongest lifting capacity over the rear due to the stabilizer configuration. ________________________________________ 8. The term superstructure or upper works refers to: • A) Below the turntable • B) Above the turntable • C) The tracks or wheels • D) The outriggers Answer: B) Above the turntable Rationale: The superstructure or upper works includes all components above the turntable, including the cab, boom, and machinery. ________________________________________ 9. The term "assist crane" is defined as: • A) A crane used only for maintenance • B) A crane used to assist in assembling and disassembling a crane • C) A backup crane for emergencies • D) A crane with reduced capacity Answer: B) A crane used to assist in assembling and disassembling a crane Rationale: An assist crane is specifically used to help with the assembly and disassembly of other cranes on site. ________________________________________ 10. When traveling a mobile crane with two cabs, the following short audible signals shall be used: • A) One stop, two go ahead, three back up • B) One stop, two go ahead, four back up • C) One stop, two go ahead, three back up • D) Two stop, one go ahead, three back up Answer: C) One stop, two go ahead, three back up Rationale: Standard audible signals for two-cab cranes are: one short signal for stop, two for go ahead, and three for back up. ________________________________________ LOAD CHARTS AND CAPACITIES 11. According to ASME B30.5, what percentage should not be exceeded on a mobile crane during a load test? • A) 85% • B) 100% • C) 110% • D) 125% Answer: B) 100% Rationale: ASME B30.5 requires that load tests not exceed 100% of the rated capacity for mobile cranes. ________________________________________ 12. The radius on a crane chart refers to: • A) Distance from the boom tip to the load • B) Center of rotation to center of gravity of the load or hook • C) Distance from the outrigger to the load • D) Boom length measurement Answer: B) Center of rotation to center of gravity of the load or hook Rationale: Radius is measured from the center of rotation to the center of gravity of the suspended load or hook. ________________________________________ 13. What percentage is the manufacturer's rated capacity of a mobile crane on outriggers? • A) 75% • B) 80% • C) 85% • D) 90% Answer: C) 85% Rationale: Mobile cranes on outriggers are rated at 85% of tipping capacity according to manufacturer standards. ________________________________________ 14. What percentage is the manufacturer's rated capacity of a rough terrain crane on rubber? • A) 65% • B) 70% • C) 75% • D) 80% Answer: C) 75% Rationale: Rough terrain cranes on rubber are rated at 75% of tipping capacity. ________________________________________ 15. If you are at a radius below the bold line on a load chart, which does that mean? • A) Structural capacity limits the lift • B) Tipping, stability limits the lift • C) Boom strength limits the lift • D) Hydraulic capacity limits the lift Answer: B) Tipping, stability limits the lift Rationale: The bold line on a load chart separates structural capacity from stability-limited capacity. Below the line, stability is the limiting factor. ________________________________________ 16. If boom lengths are in between on the load chart, you should always: • A) Use the next longer boom length capacity • B) Use the next shorter boom length capacity • C) Use lowest capacity of the next longer or shorter boom length • D) Interpolate between the two Answer: C) Use lowest capacity of the next longer or shorter boom length Rationale: When the actual boom length falls between chart values, you must use the lowest capacity of the adjacent boom lengths for safety. ________________________________________ 17. If radius is in between on the load chart, you should use: • A) Next shorter radius • B) Next longer radius • C) Average of the two • D) The higher capacity Answer: B) Next longer radius Rationale: Using the next longer radius provides a conservative capacity estimate for safety. ________________________________________
