Concrete delivery and placing machines
2.5 Placing booms
2.5.1 Unfolding the
placing boom
Only raise a mobile placing boom from the driving position once
the machine has been supported in accordance with the Operating
Instructions. Stationary booms may only be raised after the proper
set–up has been checked by a subject expert.
Only raise the placing boom in the sequence described in the
Operating Instructions. The correct sequence depends on the
folding system (roll–and–fold system, Z–fold system, etc.).
Always ask the site management to supply you with an assistant to
act as a signaller. Agree clear hand signals or other signals with the
signaller so that you can communicate with each other. You should
position the signaller such that he can always observe the whole of
the placing boom. Your primary duty as the machine operator is to
observe the site of concrete placement.
Only slew the placing boom over persons when the end hose is
empty. There is a risk of concrete falling out of the end hose.
