NCCCO TLL (Telescopic Boom Crane—Swing Cab) Representative Study Guide
Exam Sections & Topic Areas:
1. Site & Setup
2. Operations
3. Technical Knowledge
4. Safety & Regulations
Sample Representative Questions & Answers
Section 1: Site & Setup
1. What is the PRIMARY purpose of conducting a site assessment before crane setup?
A. To estimate fuel consumption for the day
B. To identify potential hazards such as power lines, unstable ground, and inadequate overhead
clearance
C. To determine the fastest route for load placement
D. To check the weather forecast for the week
2. When setting up on outriggers or crawlers, what must be done before lifting any load?
A. Verify the load chart is in the cab.
B. Ensure all outrigger floats or crawler tracks are fully seated and the crane is level.
, C. Sound the horn twice.
D. Ask the spotter if it looks good.
3. According to ASME B30.5, what is required when a crane is to be operated within its rated
capacity but within ______ of its tipping radius?
A. 50%
B. 75%
C. 85%
D. 100%
Section 2: Operations
4. The term "boom hoist limit device" refers to a system that:
A. Controls the speed of the boom extension.
B. Prevents the boom from being lowered too far.
C. Prevents the boom from being raised past its highest allowable angle.
D. Measures the weight of the load on the hook.
5. What is "two-blocking" and why is it dangerous?
A. Using two hooks on a single load; it can cause imbalance.
B. When the load block or hook assembly makes contact with the boom tip, causing extreme
stress and potential failure.
C. Operating two cranes simultaneously; it requires complex communication.
D. Lifting a load with two separate slings; it can cause crushing.
6. When making a lift with multiple-part rope, the operator must remember that rated
capacity will decrease as the number of parts of line increases if:
A. The boom is extended.
B. The boom angle is low.
C. The hook block is not equipped with a sheave guard.
D. The hoist drum is not being used to its full capacity. (Note: This is a trick question. Capacity
generally increases with more parts of line due to mechanical advantage. The correct concept
tested is often about reeving and the effects of friction and fleet angle.) A better representative
answer would be: The operator must consult the load chart for the specific reeving
configuration.
Section 3: Technical Knowledge
7. What does the term "gross capacity" refer to on a load chart?
A. The weight of the crane itself.
B. The maximum weight the crane can lift in a perfectly controlled lab environment.
