1. A crane is positioned on a site where the ground appears firm, but the
ground has recently been excavated and backfilled. What should the
operator do before setting up the crane?
A. Set the outriggers normally because the surface appears level
B. Reduce the load capacity by 10%
C. Verify that the supporting surface has adequate capacity and stability for the
crane and imposed loads
D. Operate only at half throttle
Answer: C. Verify that the supporting surface has adequate capacity and
stability for the crane and imposed loads
The supporting surface must be capable of safely supporting the crane,
including outrigger reactions. Recently disturbed or backfilled ground requires
particular attention.
2. When determining whether a planned lift is within the crane's rated
capacity, which factor is most critical?
A. Engine horsepower alone
B. Load weight and the applicable load-chart configuration and radius
C. Length of the operator's experience
D. Wind direction only
Answer: B. Load weight and the applicable load-chart configuration and
radius
Rated capacity depends on the specific crane configuration and operating
conditions. The operator must use the correct load chart and account for the
operating radius and configuration.
3. A load weighs 18,000 lb. The rigging equipment weighs 1,200 lb and the
lifting device attached below the hook weighs 800 lb. What total load
must be considered for the crane?
,A. 18,000 lb
B. 19,200 lb
C. 19,800 lb
D. 20,000 lb
Answer: D. 20,000 lb
The crane must account for the load plus applicable below-the-hook
equipment: 18,000 + 1,200 + 800 = 20,000 lb.
4. What happens to crane capacity generally as the operating radius
increases?
A. Capacity increases
B. Capacity remains unchanged
C. Capacity generally decreases
D. Capacity becomes unlimited
Answer: C. Capacity generally decreases
As radius increases, the load creates a greater overturning moment, reducing
the crane's allowable capacity.
5. A crane's load chart gives a maximum capacity of 25,000 lb at a
particular configuration. The planned load, including applicable lifting
accessories, weighs 24,800 lb. What is the most appropriate conclusion?
A. The lift is automatically safe because the load is below capacity
B. The lift is safe only if all other applicable conditions and chart requirements
are satisfied
C. The operator may increase the radius during the lift
D. The operator may exceed the chart capacity by 10%
Answer: B. The lift is safe only if all other applicable conditions and chart
requirements are satisfied
Being below the chart value does not by itself make a lift safe. Configuration,
radius, boom length, counterweight, wind, ground conditions and other
limitations must also comply.
6. What is the primary purpose of an outrigger?
,A. Increase engine speed
B. Reduce boom length
C. Stabilize and support the crane during operation
D. Increase wire-rope speed
Answer: C. Stabilize and support the crane during operation
Outriggers transfer crane reactions to the supporting surface and increase
stability when properly deployed.
7. If a crane is equipped with outriggers but the manufacturer's
instructions require them to be fully extended for a particular load chart,
what should the operator do?
A. Use the partially extended chart regardless of the manufacturer's
instructions
B. Fully extend the outriggers as required
C. Remove the counterweight
D. Increase the load radius
Answer: B. Fully extend the outriggers as required
The load chart must correspond to the actual crane configuration. Incorrect
outrigger configuration can invalidate the rated capacity.
8. What is the main danger of side loading a crane boom?
A. It improves stability
B. It can impose forces for which the boom is not designed
C. It reduces the load weight
D. It increases the crane's rated capacity
Answer: B. It can impose forces for which the boom is not designed
Crane booms are primarily designed for loads applied within their permitted
operating geometry. Side loading can cause structural damage or instability.
9. What should an operator do if the load begins to swing unexpectedly?
A. Accelerate the hoist immediately
B. Stop or control the movement smoothly and determine the cause
C. Swing the load faster in the opposite direction
D. Release the load
, Answer: B. Stop or control the movement smoothly and determine the cause
Sudden or uncontrolled movements can increase dynamic loading and create
hazards to personnel and equipment.
10.Why should sudden acceleration and braking be avoided during lifting?
A. They reduce fuel consumption
B. They eliminate all dynamic forces
C. They can create shock loading and increase forces in the crane and rigging
D. They increase rated capacity
Answer: C. They can create shock loading and increase forces in the crane
and rigging
Abrupt movements can produce dynamic loads substantially greater than the
static weight of the load.
11.Which condition requires the operator to stop a lift immediately?
A. The load is centered and stable
B. A required signal is unclear or communication with the signal person is lost
C. The load is within the chart capacity
D. The hook is above the load
Answer: B. A required signal is unclear or communication with the signal
person is lost
The operator should not continue a lift when required communication is lost or
an unsafe signal is received.
12.During a lift, two people give the operator conflicting signals. What
should the operator do?
A. Follow the faster signal
B. Follow whichever person is closest
C. Stop the operation until the correct signal and communication are
established
D. Follow both signals simultaneously
Answer: C. Stop the operation until the correct signal and communication are
established
