Section 1: Site and Crane Setup (15 Questions)
1. What is the primary purpose of outrigger pads or crane mats?
A) To provide a flat surface for the crane to sit on.
B) To increase the crane's lifting capacity.
C) To distribute the crane's weight and ground bearing pressure over a larger area.
D) To level the crane for operator comfort.
2. When performing a lift, the operator must ensure the crane is level to
within:
A) 1 percent.
B) 3 percent.
C) 5 percent.
D) The level indicator's tolerance is not critical for most lifts.
3. A critical step during crane setup is to consult the:
A) Operator's manual and load chart.
B) Signal person's handbook.
C) OSHA 300 log.
D) Company safety policy manual.
4. What must be done if a crane is set up on a soft or unstable surface?
A) Proceed with the lift but at a reduced capacity.
B) Use proper cribbing/mats to create a stable foundation.
C) Have the signal person monitor the outriggers during the lift.
D) Counterweight the crane to compensate.
,5. The rated capacity of a crane is based on all of the following EXCEPT:
A) Boom length and angle.
B) Radius to the load.
C) The weight of the load being lifted.
D) The speed at which the load is lifted.
6. When extending the telescopic boom, you should generally extend which
sections first?
A) The outermost (tip) sections first.
B) The innermost (base) sections first.
C) It does not matter as long as they are extended.
D) Alternate between inner and outer sections.
7. The load chart is valid only when the crane is:
A) On a barge.
B) Set up correctly on a firm, level surface.
C) Operating on rubber without outriggers.
D) Being used for critical lifts.
8. The primary reason for knowing the crane's weight and the ground
conditions is to:
A) Calculate transportation costs.
B) Prevent the crane from tipping or the ground from failing.
C) Determine the fuel consumption.
D) Inform the project manager.
9. Before starting the crane, the operator should ensure that:
A) The load chart is in the cab.
B) All personnel are clear of the crane's moving parts.
C) The radio is charged.
D) The weather is clear.
10. What information is found on a load rating chart?
A) The crane's serial number and manufacturer.
B) The maximum allowable load for various boom lengths and radii.
, C) The recommended cable spooling patterns.
D) The crane's transport dimensions and weight.
11. A swing cab crane's stability is most affected by operating with the boom:
A) Over the front.
B) Over the side.
C) Over the rear.
D) It is equally stable in all directions.
12. The "radius" in a load chart is the horizontal distance from:
A) The front of the crane to the load.
B) The center of the crane's rotation to the center of the load.
C) The operator's cab to the load.
D) The outrigger pad to the load.
13. When using outriggers, they must be:
A) Set and pinned.
B) Set only on concrete.
C) Slightly lifted to allow for movement.
D) Used only for lifts over 75% of capacity.
14. A daily crane inspection should be performed by:
A) The certified crane operator.
B) The site supervisor.
C) The rigger.
D) A qualified mechanic.
15. If you discover a defect during your inspection, you must:
A) Log it and continue working.
B) Report it to your supervisor and take the crane out of service until it is repaired.
C) Only avoid using the defective function.
D) Repair it yourself if it's minor.
