#1
Which of the following is a key principle of safe rigging?
Using worn-out slings for lighter loads
Inspecting rigging equipment before each use
Ignoring load weight limits
Skipping safety training for experienced workers
#2
What does SWL stand for in rigging and lifting?
Safe Working Load
Strong Wire Lanyard
Stable Weight Limit
Standard Winch Load
#3
What is the primary purpose of a shackle in rigging?
To secure the load to the crane hook
To connect two slings together
To provide a connection point for lifting
To measure the weight of the load
#4
Which factor is NOT considered when determining the appropriate sling for a lift?
Weight of the load
Distance the load will be lifted
Weather conditions
Material of the load
#5
What does the term 'choker hitch' refer to in rigging?
A hitch used to lift loads vertically
A hitch that tightens around the load's diameter
A hitch that connects two slings together
A hitch used to lift loads horizontally
#6
What is the recommended approach for securing a load during transport?
Use a hitch that allows the load to swing freely
Ensure the load is tightly secured and cannot shift
Attach the load directly to the crane hook without additional securing
Use only one securing method for simplicity
#7
Which hitch is commonly used to lift a load vertically?
Basket Hitch
Choker Hitch
Vertical Hitch
Bridle Hitch
#8
What is the recommended approach when dealing with overhead power lines during lifting operations?
Ignore them if they're not directly above the lift
Use tag lines to keep loads clear
Increase the lifting speed to minimize exposure time
Have workers carry loads directly under the power lines
#9
What is the main advantage of using synthetic slings over wire rope slings?
Higher weight capacity
Greater flexibility
Lower cost
Better durability
#10
What is the purpose of conducting a pre-use inspection of rigging equipment?
To identify any defects or damage
To determine the load weight
To calculate the lifting speed
To choose the appropriate hitch
#11
Why is it important to calculate the load's center of gravity before lifting?
To estimate the lifting speed
To determine the appropriate hitch
To prevent the load from tipping over
To calculate the load weight
#12
Which of the following is NOT a factor to consider when planning a lift?
Type of rigging equipment to be used
Experience level of the crane operator
Environmental conditions
Weight of the load
#13
When should a lift plan be developed?
Only for complex lifts
Never, it's unnecessary
After the lift has already started
Before any lifting operation begins
#14
What should be done if a load is found to be unbalanced during a lift?
Continue the lift and adjust the balance afterward
Stop the lift and redistribute the load weight
Increase the lifting speed to stabilize the load
Ignore the imbalance and proceed cautiously
#15
What is the purpose of using outriggers or stabilizers during lifting operations?
To increase the lifting capacity of the crane
To stabilize the crane and prevent tipping
To reduce the height of the load
To provide additional attachment points for rigging
#16
What is the primary purpose of a lift director on a job site?
To operate the crane
To oversee the lifting operation and ensure safety
To rig the load
To calculate load weight
#17
What is the role of a signaler in a lifting operation?
To operate the crane
To direct the crane operator using hand signals or radio communication
To inspect rigging equipment
To calculate load weight
