Chapter 7 Preparing for crane operation
Working range
Danger!
There is acute danger to life for operators and others in the entire
working range of the crane (slewing range and under suspended
loads). Allowing bystanders in the working range is grossly negligent.
The operator must have full view of the crane movements and the loading/unloading point. If this is
impossible the operator must be aided by a qualified signaller. Communication must be
established between operator and signaller (radio device or similar).
The entire working range of the crane is a danger zone.
No other work may be carried out within the working range.
The entire working range must be lit during twilight or darkness so that the work can be carried out
safely.
Danger!
In case of insufficient visibility stop work immediately.
