Correct mixing of the concrete influences pumping performance.
Mix the concrete vigourously in the truck mixer at maximum
speed. Ensure that the concrete mix is uniformly prepared.
If concrete additives are required (liquefier, set retarding ad-
mixture), continue mixing after their addition for at least 4 minu-
tes.
Pour the concrete from the truck mixer, silo, etc. into the agita-
tor hopper.
Switch the agitator on.
Start pumping.
Notes
Start with a low flow rate and increase it continuously after several
cubic metres.
Your machine is operated economically with a diesel engine drive if
you select engine speed and output regulation so that the drive mo-
tor does not run at an excessive speed at low load.
