1. The main purpose of a tower crane’s counterweight is to:
a) Increase lifting speed
b) Balance the load
c) Reduce wind sway
d) Support the jib
Counterweights help stabilize the crane and prevent tipping by
balancing the weight of the load being lifted.
2. When operating a tower crane, the operator should always check:
a) Fuel level only
b) Wind direction only
c) Load chart, rigging, and crane condition
d) Paint condition
Operators must check all safety-critical components before operation to
ensure safe lifts.
3. The maximum rated load of a crane must never be exceeded
because:
a) It voids the warranty
b) It reduces fuel efficiency
, c) It can cause structural failure or tip-over
d) It slows down lifting speed
Exceeding the rated load can compromise the crane’s structural integrity
and cause accidents.
4. The purpose of the load chart is to:
a) Show fuel consumption
b) Determine safe lifting capacity based on boom length and
radius
c) Schedule maintenance
d) Identify operator shifts
Load charts indicate the maximum allowable loads at various boom
lengths and angles.
5. Before starting a lift, a crane operator must:
a) Turn on the radio
b) Inspect the crane and the surrounding area
c) Call the manufacturer
d) Refuel the crane
Pre-operation inspection helps identify hazards and ensures the crane is
safe to operate.
6. When lifting personnel in a basket using a tower crane, the
operator must:
a) Lift slowly only
b) Follow manufacturer guidelines and Alberta OH&S regulations
c) Ensure only one person is in the cab
d) Use the crane at full load
, Personnel lifts are highly regulated and require strict compliance with
safety standards.
7. The term “radius” in crane operation refers to:
a) The boom length
b) The horizontal distance from the crane’s center to the load
c) The counterweight distance
d) The height of the hook
The radius affects the crane’s lifting capacity and stability.
8. Wind can affect crane operations by:
a) Lubricating moving parts
b) Causing swaying or tipping
c) Increasing lift speed
d) Reducing counterweight efficiency
High winds can destabilize a crane and make loads swing, increasing
risk of accidents.
9. The tower crane’s hoist brake is designed to:
a) Slow the crane cab
b) Stop the slewing motion
c) Hold the load securely in position
d) Increase lifting speed
Hoist brakes prevent the load from falling if the operator releases the
controls.
10. Load rigging should always be:
a) Over-tightened
b) Inspected for damage and properly secured
