1. What is the primary purpose of a crane’s load chart?
A. To show crane fuel capacity
B. To provide safe working load limits for various configurations
C. To list operator certifications
D. To identify maintenance schedules
Rationale: Load charts are used to determine safe lifting capacities at
various boom lengths and angles.
2. What is the most critical factor when evaluating ground conditions for
crane setup?
A. Weather conditions
B. Soil bearing capacity
C. Operator experience
D. Length of boom
Rationale: Soil bearing capacity determines stability and prevents tipping.
3. What component prevents the crane from lifting beyond safe limits?
A. Outrigger pads
B. Boom hoist
C. Rated capacity limiter (RCL)
D. Load block
Rationale: The RCL system alerts or restricts operators from exceeding
safe load limits.
,4. Which signal means “stop” when given by a signal person?
A. Swing slowly
B. Raise the load
C. Stop all crane movement
D. Lower the load
Rationale: A flat hand held up means immediate stop.
5. For daily inspections, what must be checked on a crane?
A. Oil change history
B. Hooks, ropes, and safety devices
C. Fuel level
D. Operator’s lunch
Rationale: Critical components affecting safety must be checked daily.
6. What is the purpose of outriggers?
A. To increase speed
B. To stabilize the crane
C. To lift loads
D. To reduce noise
Rationale: Outriggers extend the crane’s support base to prevent tipping.
7. What is the definition of gross capacity?
A. Net weight of load
B. Maximum rated load for a configuration
C. Weight of crane only
D. Weight of boom
Rationale: Gross capacity is the crane’s maximal safe lifting limit.
8. What should be done if a load feels unstable during lifting?
A. Increase speed
B. Ignore it
C. Signal to swing faster
D. Lower the load safely and reassess
Rationale: Unstable loads must not be moved until properly secured.
9. What is the rated capacity of a crane?
A. Maximum engine power
B. Maximum load crane can lift in a specific configuration
, C. Maximum fuel capacity
D. Maximum tire pressure
Rationale: Rated capacity is configuration-specific load limit.
10.Which part of the crane supports the boom?
A. Superstructure
B. Counterweight
C. Outriggers
D. Hook block
Rationale: The superstructure holds major components including the
boom.
11.Before lifting over people, what is required?
A. Nothing
B. Faster lifting
C. A safety plan and authorized exclusion zone
D. Lower speed
Rationale: Overhead lifts require exclusion zones to prevent injury.
12.What type of maintenance should be performed by a qualified technician?
A. Daily cleaning
B. Fueling
C. Component repair and adjustments
D. Personal inspection
Rationale: Complex repairs need trained technicians.
13.What does a red tag on an equipment component indicate?
A. Low fuel
B. Component is out of service
C. Component is brand new
D. Inspection due
Rationale: Red tags identify non-serviceable parts.
14.When lifting near power lines, what is the minimum clearance required?
A. 5 feet
B. 10 feet or as regulated
C. 3 feet
