2.6.4 Opening delivery lines
Delivery lines must not be opened or tapped off while they are pres‐
surised. Concrete exiting under pressure can cause injury. The con‐
crete column must be depressurised by reverse pumping before the
delivery line is opened. Never bend over the coupling when you are
working.
2.6.5 Clearance to delivery lines
Noone should remain in the vicinity of separate delivery lines during
pumping operations. Cordon off the danger zone. If it is not possible
to place a large enough cordon around the danger zone, the delivery
line must be covered by suitable means.
2.6.6 Securing the delivery lines
Delivery lines, in particular riser lines which are not laid along placing
booms, must be securely fastened in order to transfer the forces gen‐
erated in them into the structure or other structural members. The
lines must be laid so as to avoid kinks, sharp bends, stresses and
damage during pumping operations.
2.6.7 Continuation delivery lines
If a continuation delivery line is connected to the placing boom, it
must not place any further strain on the placing boom.
While you connect, use and disconnect a continuation delivery line,
you must switch off the placing boom control system to prevent unin‐
tended movements of the placing boom. There is a risk of accident
posed by jerky movements of the boom tip.
