CONCRETE PUMPING
Ensure material outflow does not create dangers in the unload area before starting pumping.
- When the pumping barrels' inlets and/or wear plate surface from the hopper full of grout, pour the concrete in hopper and
activate the electric vibrator by means of selector 6 (FIG.5-1), then start pumping at low flow rate.
- Flow rate can be increased to wanted value using the flow rate adjusting lever, when the first concrete reaches the piping
line's outfeed.
During the first few pumping cycles the operator must check the pressure on the pressure gauge 1 (FIG.5-2) that indicates that
the operating pressure of the hydraulic cylinders does not exceed too high values.
Excessive pressures are indicative of potential clogging.
The effective work pressure (on hydraulic circuit oil) varies based on used mix and layout of the piping line.
During the S valve exchange phase, pressure gauge 2 (FIG.5-2) indicates the operating pressure of the hydraulic jacks
(controlling the S valve).
The auxiliary circuit pressure gauge 3 (FIG.5-2) indicates the services' work pressure (agitator, material discharge shutter, high
pressure washer), that must be below 180 bar.
Should only the agitator be operating and the pressure gauge shows 180 bar pressure, it means that the agitator rotation is
blocked.
Check the cause and unlock it by acting on lever 7 (FIG.5-2) to reverse its rotation.
REMOTE CONTROLS
Insert the plug into the connector's socket located on the machine's bodywork 11 (FIG:5-2), if using the remote control via cable
(see par.4.3.3).
If machine is provided with radio control, connect the receiver to the connector's socket.
The LOCAL/REMOTE selector switch 7 (FIG.5-1) allows selecting the pumping controls from the control board (local) or from a
remote device [comando a distanza (di serie) o radiocomando (optional)].
