Q&A| Instant Download Pdf
1. A crane’s rated capacity refers to the maximum load the crane can lift:
A. under ideal conditions only
B. at the operator’s discretion
C. under specific configuration and conditions **
It is defined as the maximum load the crane is designed to lift in a
stated configuration.
D. without regard to boom angle
2. When performing a pre-operation inspection, the operator should
check for:
A. color of paint
B. worn wire rope **
Worn or damaged wire rope is a critical safety hazard that must be
identified before use.
C. operator’s lunch schedule
D. ambient temperature
3. The purpose of a load chart on an overhead crane is to:
A. list maintenance dates
B. display lifting capacity at different configurations **
Load charts show how capacity varies with boom angle, radius, and
other factors.
C. record operator hours
D. show hook color preferences
,4. Overloading a crane can result in:
A. enhanced performance
B. structural failure **
Exceeding rated capacity can cause structural components to yield or
break.
C. reduced fuel consumption
D. less sway
5. The safety factor for an overhead crane component is the ratio of:
A. actual capacity to test capacity
B. test capacity to actual capacity **
Safety factor = test stress capacity ÷ maximum expected load;
ensures margin of safety.
C. rated speed to actual speed
D. weight to temperature
6. A key reason for using tag lines during a lift is to:
A. decorate the load
B. stabilize the load **
Tag lines allow personnel to control load rotation and sway during
movement.
C. speed up the lift
D. identify load owner
7. Before each shift, operators must inspect the crane’s:
A. entertainment system
B. lifting devices **
Lifting devices (hook, sling, rigging) must be examined for defects.
C. coffee maker
D. satellite radio
8. The most reliable way to stop a moving load when signals are unclear
is to:
A. guess the signal
B. stop the lift **
Ceasing movement protects personnel and equipment until signals
are clear.
C. continue slowly
D. honk horn repeatedly
, 9. A deflection limit is associated with which crane component?
A. hook
B. rail **
Rails have deflection limits that affect stability and tracking.
C. boom tip
D. hydraulic fluid
10. When operating near a power line, the minimum safe approach
distance is determined by:
A. load weight
B. voltage level **
Higher voltage requires greater clearance to prevent arcing.
C. wind speed
D. operator age
11. A tag out requirement means:
A. label unused tools
B. equipment is disconnected and not to be operated **
Tag out indicates energy sources are isolated and equipment is
unsafe to operate.
C. mark load center
D. lower all loads
12. A crane’s hoist brake must be able to hold the load when:
A. the crane is idle **
The brake must prevent load drift or descent when not intentionally
moved.
B. lights are off
C. radio is playing
D. the hook is empty
13. The first step in a pre-lift planning procedure is to:
A. call supervisor
B. assess the load and area **
Planning begins by understanding load characteristics and
environmental conditions.
C. start the crane
D. test emergency stop
