Never bend the end hose over. Never attempt to straighten a bent
end hose by increasing the pressure. The end hose must not be sub
merged below the surface of the concrete being delivered, otherwise
the concrete may spray upwards.
The concrete may also spray from the end hose due to the presence
of air in the delivery line. To prevent this from occurring, the hopper
must be filled with concrete at least as far as the agitator shaft so
that no air can be sucked in.
The end hose must be secured against falling.
The hoseman must guide the end hose in such a way that prevents
excess spraying of concrete, and so that concrete is directed pre
cisely into the site of concrete placement.
Control the placing boom so that the hoseman can guide the end
hose without power consumption. The hoseman must not carry the
end hose by hand, because the weight of it may cause permanent
personal injury.
If a drill is connected to the delivery line for the placing boom, it must
not place any further strain on the placing boom. The placing boom
must be connected to the drill in such a way that the placing boom
does not require adjustment. There should be 1
− 2 delivery hoses be
tween the placing boom and the drill; these must be secured so that
they cannot move in an uncontrolled manner. If the drill is moved on
the construction site, the placing boom must not be connected.
