3.22.2 MARKING OF THE PUMPING LINE
ON THE PLACING BOOM
A distinctive type plate is located on the placing
boom (Fig.: 5) for the placing boom pumping
line. The type plate for 4-section placing booms
has the same structure. The nominal sizes
(DN) specified on this type plate are the
maximum allowable.
The nominal sizes and the wall thicknesses of
the pumping line and the gross density of the
pumped concrete must not exceed the
specified limits.
The maximum operating pressures (PN)
specified on the components and type plates
are the maximum permissible operating
pressures for components in new condition. If
the minimum wall thickness is not met, then
replace tubes and elbows.
With truck-mounted concrete pumps, the
concrete pressure for rod and piston-side
pressure is also indicated on the type plate of
the concrete pump Fig.: 6.
If no value is given for the rod side, it refers to a
piston-sided pressurised concrete pump.
This concrete pump may not be interchanged!
