1. Which type of crane is most suitable for lifting heavy loads in
confined areas?
a) Tower crane
b) Overhead crane
c) Crawler crane
d) Floating crane
Crawler cranes are mobile and can maneuver heavy loads in areas
where space is limited.
2. The purpose of a load chart is to:
a) Track maintenance schedules
b) Estimate fuel consumption
c) Determine safe lifting capacities
d) Identify operator qualifications
A load chart provides the maximum allowable loads at different
boom lengths and angles.
3. When signaling a crane, the standard signal for “stop” is:
a) One arm extended horizontally
b) Both arms raised vertically
c) Arm waving up and down
d) Making a circular motion with one arm
, Both arms raised vertically is the universal hand signal to stop
crane operations.
4. Which factor most affects crane stability during a lift?
a) Operator experience
b) Load radius and ground conditions
c) Type of rigging
d) Weather alone
The combination of load radius and ground conditions directly
influences the crane’s tipping point.
5. Before lifting, the operator must inspect:
a) Only the rigging
b) Only the crane boom
c) Only the load
d) Crane, rigging, and load
A complete inspection ensures the lift is safe and within rated
capacities.
6. The main function of outriggers is to:
a) Protect the crane cab
b) Assist with steering
c) Stabilize the crane
d) Extend the boom
Outriggers spread the load over a larger area to prevent tipping.
7. Which type of lift involves a load suspended from multiple points
to maintain balance?
a) Single-line lift
b) Tagline lift
c) Two-point or multi-leg lift
, d) Pick-and-carry lift
Multi-leg slings are used to evenly distribute weight and maintain
load stability.
8. What is the correct procedure if the crane is overloaded?
a) Increase boom angle
b) Lift faster
c) Stop the lift immediately
d) Reduce counterweight
Stopping immediately prevents structural damage or tipping.
9. Which component connects the hook to the crane’s hoist line?
a) Shackle
b) Sling
c) Hook block
d) Boom tip
The hook block is the assembly that attaches the load to the hoist
line safely.
10. A crane operator notices the boom deflecting under load.
The operator should:
a) Ignore minor deflection
b) Continue the lift slowly
c) Stop the lift and inspect
d) Increase counterweight
Boom deflection can indicate overloading or structural issues,
requiring immediate inspection.
11. The term “load radius” refers to:
a) The weight of the load
b) The length of the hoist line
