In which situation must a signal be provided to the crane operator?

A signal must be provided to the crane operator when the view in the direction of travel is obstructed. In such situations, the operator cannot clearly see the area where the load is being moved, which increases the risk of an accident or collision. Providing clear signals ensures that the operator is informed about the movements required and can proceed safely, relying on the signals to guide them when visibility is compromised. This practice enhances overall safety by mitigating the likelihood of incidents that could arise from unseen hazards.

While there are circumstances where the operator might not need additional signals, such as when they have full visibility of the load or when the load is directly above them, these do not warrant the same level of caution as situations where visibility is limited. Similarly, a load resting on the ground typically does not require signals for movement since it is stationary and under control.
