1. What is the primary purpose of a load chart on an articulating
boom crane?
a) To show fuel capacity
b) To display hydraulic pressures
c) To indicate safe lifting capacities at various boom positions
d) To list operator maintenance duties
Load charts provide the maximum safe loads for different boom lengths
and angles, ensuring safe operation.
2. When performing a pre-shift inspection, which of the following is
most critical?
a) Checking the radio
b) Inspecting wire ropes, hooks, and boom sections for damage
c) Washing the crane
d) Recording working hours
Structural components and lifting devices are critical for safety; defects
can lead to catastrophic failure.
3. What is the recommended way to travel with a load suspended on
a knuckleboom crane?
a) As fast as possible
, b) Only during turns
c) Never travel with a suspended load
d) Only in reverse
Traveling with a suspended load can destabilize the crane and is
prohibited under safety regulations.
4. What does the term “outrigger spread” refer to?
a) Length of the boom
b) Distance the hook can extend
c) Distance between the extended outriggers
d) Width of the operator cab
The outrigger spread stabilizes the crane; wider spreads allow for higher
lifting capacities.
5. Which factor has the greatest effect on crane stability?
a) Fuel level
b) Operator skill
c) Ground conditions and outrigger setup
d) Weather forecast
Even a skilled operator cannot compensate for unstable ground; proper
support is essential for safe lifts.
6. How often must crane wire ropes be inspected visually?
a) Monthly
b) Annually
c) Before each shift
d) Every 5,000 hours
Visual inspection of wire ropes before use ensures early detection of
wear, fraying, or damage.
, 7. What is the purpose of a boom angle indicator?
a) To measure wind speed
b) To measure engine temperature
c) To show the boom’s angle relative to horizontal
d) To monitor fuel efficiency
Knowing the boom angle is essential for determining safe lifting
capacities.
8. When lifting near power lines, what is the minimum safe distance
in Alberta?
a) 2 m
b) 3 m for lines up to 750 kV
c) 10 m
d) 1 m
Keeping a minimum distance prevents electrocution hazards; exact
distances are regulated by safety codes.
9. What should you do if the crane starts to tip during a lift?
a) Continue lowering the load
b) Speed up the lift
c) Stop all motion and lower the load safely if possible
d) Jump off the crane
Immediate action is required to prevent overturning; stopping motion is
the safest response.
10. Which type of maintenance schedule is recommended for
hydraulic cylinders?
a) Only when leaking
b) Yearly
