Страница: 92 / 390

The diameter of the danger zone is twice the end hose length. Do not
guide the end hose when pumping is started. There is a risk of acci‐
dent from the end hose swinging out or stones being ejected.
When using a longer end hose, the diameter of the danger zone
(Ex‐
tending the placing boom and end hose P. 21)
also increases.
End hoses with a length of more than 4 m must not be guided by
hand.
There is a risk of injury to the hoseman if the end hose becomes
caught in the reinforcement and suddenly jumps out on further move‐
ment of the placing boom.
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.
2.5.3 Guiding the end hose ergonomically
The hoseman must guide the end hose in such a way that prevents
excess spraying of concrete, and so that concrete is directed precise‐
ly 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.
