Safety manual
Concrete delivery and placing machines
Danger zone
The danger zone is the area surrounding the machine, in which
people may be at risk of injury from movements required by the
work.
The danger zone varies within the working area and depends on
the activity being carried out and the position of the placing boom.
Danger zones must be secured and clearly identified. The machine
operator must be capable of seeing the danger zone at all times
and under all circumstances. If necessary he must appoint a signaller
to supervise the danger zone.
Depending on the working situation, workplaces may occasionally
fall within the danger zone, especially the workplace of the hoseman
and the truck mixer driver. If a workplace falls within the
danger zone, increased caution is required and suitable personal
protective equipment is prescribed. Persons who are authorized to
be present in such a workplace, must use their own discretion to
assess the hazards of the situation and be able to react accordingly.
The machine operator is responsible for safety in the danger zone
of the machine whilst the machine is in use.
The machine operator must stop work immediately and press the
EMERGENCY STOP button if an unauthorized person enters the
danger zone.

support feet
Placing boom
There is a danger of crushing in the swing–out and extension zone
for the supports.
The danger zone when working with the placing boom is the zone
over which the placing boom is slewed. In this area there is a risk
of injury from falling concrete and delivery line components.
