-
When authorized by the supervisor
-
At all times to control the loads
-
When authorized by the rigger
Correct Answer
A. At all times to control the loadsExplanation
Tag lines are used at all times to control the loads. Tag lines are ropes or straps attached to a load to help guide and control its movement during lifting or lowering operations. They are essential for maintaining control and stability of the load, especially in situations where it may swing or spin. By using tag lines, workers can ensure that the load is properly positioned and prevent it from causing any damage or accidents. Therefore, tag lines should be used consistently to control loads, regardless of the weather conditions or authorization from supervisors or riggers.Rate this question:

What affects the capacity of a crane?
-
The service date
-
The boom length
-
The identification plan
-
The inspection date
Correct Answer
A. The boom lengthExplanation
The capacity of a crane is affected by the boom length. The longer the boom length, the higher the capacity of the crane. This is because a longer boom allows the crane to reach greater heights and lift heavier loads. The boom length determines the maximum radius and height at which the crane can operate effectively. Therefore, a crane with a longer boom length will have a greater capacity compared to a crane with a shorter boom length.Rate this question:

What is the correct position of the outriggers before lifting operation can be started?
-
Retracted
-
Extended
-
Over the rear
-
Stowed
Correct Answer
A. ExtendedExplanation
Before a lifting operation can be started, the correct position of the outriggers is extended. Outriggers are devices used to provide stability and support to cranes or other lifting equipment. By extending the outriggers, the base of the equipment is widened, increasing its stability and preventing it from tipping over during the lifting process. Therefore, it is necessary to have the outriggers fully extended and securely in place before commencing any lifting operation.Rate this question:
