1. What is the primary purpose of a crane's load chart?
a) To determine the crane's speed
b) To calculate fuel consumption
c) To determine safe lifting capacities at various boom lengths
and angles
d) To measure operator skill
Load charts provide the maximum safe load for different boom
lengths and angles, ensuring safe operation.
2. Which factor most affects a crane’s lifting capacity?
a) Operator experience
b) Boom length and radius
c) Weather conditions
d) Type of tires
Lifting capacity decreases as the boom length increases and the
radius from the load center increases.
3. What is the purpose of outriggers on a mobile crane?
a) To improve fuel efficiency
b) To stabilize the crane during lifting operations
c) To increase lifting speed
d) To reduce wind effects
, Outriggers extend the crane’s base, providing stability and
preventing tipping.
4. When inspecting a crane before use, what should be checked
first?
a) Operator license
b) Structural integrity and safety devices
c) Weather conditions
d) Load charts
Initial inspections focus on structural components and safety
devices to ensure the crane is safe to operate.
5. Which of the following is considered a critical lift?
a) Lifting under 50% capacity
b) Lifting over water or above personnel
c) Lifting in calm weather
d) Routine material handling
Critical lifts involve additional risk due to location, load, or
potential consequences of failure.
6. What is the purpose of a load moment indicator (LMI)?
a) To measure fuel consumption
b) To track engine hours
c) To warn when the crane is approaching its safe lifting limit
d) To control boom speed
The LMI monitors load weight and boom position to prevent
overloading.
7. How often must mobile crane inspections be performed in
Alberta?
a) Every 6 months
, b) Before each shift and annually by a certified inspector
c) Only before first use
d) Every 5 years
Daily checks ensure safe operation, and annual inspections
confirm structural integrity.
8. When operating a crane on uneven ground, what is the most
important consideration?
a) Speed of the lift
b) Leveling and stabilizing the crane
c) Color of the crane
d) Operator comfort
Uneven ground can lead to tipping; proper leveling is critical.
9. What should be done if a crane’s load begins to swing
uncontrollably?
a) Increase lifting speed
b) Stop the lift and stabilize the load
c) Continue lifting slowly
d) Signal the rigging crew to adjust
Uncontrolled swinging is dangerous and must be addressed
immediately to prevent accidents.
10. Which type of maintenance is performed daily by the
operator?
a) Overhaul of engine components
b) Visual inspections and lubrication
c) Replacing hydraulic pumps
d) Boom reconstruction
