2.5 Placing booms
2.5.1 Unfold placing boom
Only raise a mobile placing boom from the driving position once the
machine has been supported in accordance with the Operating In‐
structions. Stationary placing 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 Operat‐
ing Instructions. The correct sequence depends on the “Folding sys‐
tem” (roll-and-fold system, Z fold system, etc.).
Do not carry out more than one movement at a time. If a movement is
stopped, the entire volume of fluid is available for the remaining
movements, and can increase their speeds. Depending on the de‐
sign, it may be the case that carrying out several movements at once
(as opposed to carrying out a single movement at maximum speed at
any one time) does not bring any advantage in terms of time. Carry‐
ing out several movements at once requires an increased level of at‐
tentiveness.
The range of a radio remote control is long enough for the machine to
receive control commands (e.g. from a great distance, from inside en‐
closed spaces) even without visual contact. If there is no visual con‐
tact, for example, because you are changing workplace, you must
switch off the remote control. If there is no visual contact, for exam‐
ple, because the construction site is unclear, signallers MUST be
used, and must remain in contact with the machine operator using
suitable means, and have visual contact with the site of concrete
placement, work areas and danger zones, and the machine.
Always ask the site management to provide 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 delivery line and
end hose are empty. There is a risk of concrete falling out of the end
hose.
