IMPACT BEND
The impact bend 1(Fig.: 4) is the penultimate
bend of the boom pumping line.
The concrete frequently falls into this elbow and
the impacting material causes so-called impact
wear.
Impact wear can be mostly avoided if the last
boom section assumes a horizontal position
during the pumping procedure (Fig.: 5).
Position 1+2
= limited impact wear
Position 3
= higher impact wear
Measurement points:
Wear measurement is only possible via a
regular optical inspection, as the main wear
points vary greatly between concrete pumps.
Empirical values can be expanded individually
by measurement shown, if necessary, (Fig.: 6).
