Texas Crane Operator Certification Exam Review with
Answers and Rationales | 100% Pass Guaranteed |
Graded A+
1. What is the primary purpose of a load chart?
A. Show crane color codes
B. Determine safe lifting capacity
C. Identify operator schedule
D. Show fuel consumption
Load charts provide the maximum safe lifting capacity based on
radius, boom length, and configuration.
2. Which factor most reduces crane capacity?
A. Engine size
B. Operator experience
C. Increased load radius
D. Counterweight color
Capacity decreases as the load moves farther from the center of
rotation.
3. The center of gravity of a load should be:
A. Unknown
B. Directly under the hook
C. Near one corner
D. Above the boom tip
Keeping the center of gravity under the hook prevents load swing and
tipping.
4. Wind becomes a serious hazard for crane operations at
approximately:
,A. 5 mph
B. 10 mph
C. 20–30 mph (depending on load and manufacturer limits)
D. 60 mph
Most manufacturers specify wind limits; large loads act like sails.
5. Outriggers should be set:
A. On dirt only
B. Fully extended and on solid support when required
C. Halfway extended
D. Without pads
Proper outrigger setup ensures stability and full rated capacity.
6. What should be done before lifting a load?
A. Rev the engine
B. Perform a test lift
C. Swing quickly
D. Extend boom fully
A test lift verifies balance, rigging, and weight.
7. A crane must be level within:
A. 10 degrees
B. 5 degrees
C. Manufacturer’s specified tolerance (usually about 1%)
D. Any level is acceptable
Crane capacity assumes the crane is level.
8. Who is responsible for determining load weight?
A. Signal person
B. Rigger
, C. Operator (must verify)
D. Site supervisor only
The operator must ensure the lift is within rated capacity.
9. Side loading a crane is:
A. Recommended
B. Safe if slow
C. Prohibited
D. Allowed for light loads
Cranes are designed for vertical loads only.
10. When should a crane be taken out of service?
A. When fuel is low
B. When safety devices are not working
C. When operator is busy
D. During lunch
All safety devices must be operational.
11. The minimum approach distance from energized power lines
(up to 50 kV) is:
A. 5 feet
B. 8 feet
C. 10 feet
D. 20 feet
OSHA requires at least 10 feet clearance.
12. A qualified signal person must be used when:
A. Always optional
B. Operator’s view is obstructed
C. Only at night
