NCCCO Telescopic Boom Crane - Fixed Cab (TSS) Exam Study Guide 2026
Section 1: Load Charts & Basic Operational Knowledge (Questions 1-25)
1. What is the PRIMARY purpose of a crane's load chart?
A. To show the crane's maximum boom length.
B. To provide the operator with the rated capacities for all permissible boom lengths and radii.
C. To indicate the fuel consumption at various engine RPMs.
D. To list the crane's approved attachments.
2. Which of the following significantly REDUCES a crane's rated capacity?
A. Operating on a level, firm, and supporting surface.
B. Operating with the boom retracted.
C. Operating with the load directly over the front of the crane.
D. Operating with the boom over the side (over the tracks or tires).
3. What does the term "radius" refer to on a crane load chart?
A. The horizontal distance from the center of the crane's rotation to the hook.
B. The length of the boom from the tip to the heel pin.
C. The vertical distance from the ground to the boom tip.
D. The distance from the crane's counterweight to the load.
4. When reading a load chart, you find a capacity listed as "85% on outriggers." This indicates:
A. The crane is configured for on-rubber lifting.
B. The outriggers are fully extended and set on firm ground, and you are using the main boom
chart.
,C. The outriggers are only partially extended.
D. The crane is using an approved jib attachment.
5. The primary reason for a lift plan is to:
A. Satisfy OSHA paperwork requirements.
B. Identify all potential hazards and establish methods to mitigate them to ensure a safe lift.
C. Determine the fastest way to complete the lift.
D. Assign blame in case of an accident.
6. What is the MINIMUM distance a suspended load should be kept from power lines, as per
OSHA, when the voltage is unknown?
A. 10 feet.
B. 20 feet.
C. 50 feet.
D. It depends on the boom length.
7. "Dedgging" refers to:
A. Inspecting the wire rope for damage.
B. Using the crane's hoist to pull the load horizontally, causing the crane to drag or slide.
C. Lubricating the boom pins.
D. Cleaning mud from the tracks or tires.
8. The net capacity of a crane is defined as:
A. The total weight the crane can lift to its maximum height.
B. The gross capacity minus the weight of all rigging (slings, blocks, hook, etc.).
C. The capacity listed in the load chart for the shortest radius.
D. The capacity when using a jib.
9. When making a lift, the operator should always verify the weight of the load by:
A. Asking the rigger for their best estimate.
B. Relying on the shipping manifest or equipment data plate.
C. Lifting it just enough to see if the crane struggles.
D. Assuming it's within capacity if it's a common material.
10. A swing brake is primarily used to:
A. Hold the load in position after stopping the swing motion.
B. Emergency stop the crane in case of failure.
C. Control the speed of the boom hoist.
D. Lock the cab door during travel.
,11. What does the term "two-blocking" mean?
A. Using two sheaves in the boom tip.
B. When the hook block contacts the boom tip, causing extreme stress on the hoist system.
C. Lifting two loads simultaneously.
D. Connecting two cranes for a tandem lift.
12. When extending a telescopic boom, the operator should generally extend which sections
first?
A. The smallest (outermost) sections.
B. The largest (base) sections.
C. It doesn't matter as long as they extend evenly.
D. Only the sections with the most power.
13. The Rated Capacity Limiter (RCL) or Load Moment Indicator (LMI) is a device that:
A. Automatically stops all crane functions when overloaded.
B. Warns the operator of an approaching overload condition but does not prevent it.
C. Replaces the need for a load chart.
D. Records video of all lifts.
14. If a load chart lists different capacities for "on outriggers" and "on tires," which should
you use if your outriggers are fully extended and set?
A. Always use the "on tires" chart for safety.
B. Use the "on outriggers" chart.
C. Average the two values.
D. Use the lower of the two capacities.
15. Critical lifts often require a pre-lift meeting. Who typically MUST attend this meeting?
A. Only the crane operator and the site supervisor.
B. The crane operator, signal person, riggers, and lift director.
C. All workers on the entire job site.
D. Only the lift director.
16. Before starting the engine, the operator's first action should be to:
A. Turn on the radio.
B. Conduct a walk-around inspection of the crane and site.
C. Fasten the seatbelt.
D. Check the fuel level.
, 17. What is the function of a boom angle or radius indicator?
A. It shows the operator the height of the boom tip.
B. It provides a visual reference for the boom's position to help select the correct load chart
capacity.
C. It automatically retracts the boom if the angle is too steep.
D. It measures wind speed at the boom tip.
18. When traveling with a suspended load, the load should be kept as low as possible, and the
boom should be positioned:
A. Directly over the rear of the carrier.
B. Directly over the front of the carrier.
C. Over the side for better visibility.
D. In line with the direction of travel, typically over the front.
19. A sudden drop in hydraulic pressure is most likely an indication of:
A. Normal operation when cold.
B. A failed hydraulic pump or a major leak.
C. The engine is running too fast.
D. The load is too light.
20. The ground condition under the outrigger pads or tracks is crucial because it:
A. Determines the color of the crane.
B. Affects the crane's stability and its ability to support the intended load.
C. Only matters for mobile cranes, not crawlers.
D. Is only important for long boom configurations.
21. If you experience a loss of stability (e.g., the crane begins to tip), the correct immediate
action is to:
A. Swing the boom quickly to redistribute weight.
B. Lower the load, retract, and lower the boom if possible to reduce the radius.
C. Jump from the cab.
D. Hoist the load rapidly to get it off the ground.
22. When operating near power lines, a dedicated spotter (or "signal person") is required
when:
A. The lines are insulated.
B. The crane cannot get within 50 feet.
C. Any part of the crane, load, or line could get within 20 feet of the lines.
D. Only during night lifts.
