1. What is the primary purpose of a crane’s load chart?
A) To measure wind speed
B) To determine fuel efficiency
C) To determine safe lifting capacities at various boom
configurations
D) To schedule maintenance
Rationale: Load charts tell you how much weight can be
safely lifted based on boom length and angle.
2. According to safety standards, how often should a crane
inspection be done?
A) Only once a month
B) Only after repairs
C) Daily before use and periodic inspections as required
D) Only at the start of the year
Rationale: OSHA standards require daily and periodic
inspections to ensure safety.
3. Which signal method must be used to communicate with
a crane operator when visibility is limited?
A) Hand signals only
B) Text messaging
C) Flashlight signals
, D) Standardized hand signals or radio communication
Rationale: Standard hand or radio signals ensure clear
communication.
4. What is the safest action if a crane load begins to swing
uncontrollably?
A) Speed up the lift
B) Stop operations and secure the load
C) Change lifting direction
D) Sound the horn repeatedly
Rationale: Stopping immediately prevents accidents.
5. When using outriggers on a mobile crane, they should be:
A) Partially extended
B) Fully deployed on firm, level ground
C) Retracted during lifting
D) Only extended if lifting over capacity
Rationale: Outriggers stabilize the crane.
6. Which factor most affects crane lifting capacity?
A) Fuel type
B) Operator’s age
C) Boom length and angle (radius)
D) Weather only
Rationale: Boom radius heavily affects safe capacity.
7. A “critical lift” is defined as a lift that:
A) Takes longer than 5 minutes
B) Involves only light weights
C) Uses only tag lines
, D) Requires special planning due to unique hazards
Rationale: Critical lifts need extra planning.
8. What type of hitch provides best stability for a long,
horizontal load?
A) Single-leg hitch
B) Choker hitch
C) Spread-bridge or multiple sling hitch
D) Basket hitch only
Rationale: It spreads the weight for stability.
9. Before operating a crane, you must perform:
A) A lunch break
B) A maintenance report
C) A pre-operation inspection
D) A fuel refill
Rationale: Inspection catches defects and hazards.
10. Standard OSHA regulations for crane and derrick
safety are found under:
A) 29 CFR Part 1910
B) 29 CFR Part 1926 Subpart M
C) 29 CFR Part 1926 Subpart CC
D) 1915 Subpart F
Rationale: Subpart CC covers cranes and derricks.
11. What is “two-blocking”?
A) Lifting two loads at once
B) Failure of the outriggers
C) When the hook block contacts the boom tip
