3.5 AFTER CLEANING
- Lubricate all lubrication points after
cleaning.
- We recommend spraying the dry machine
with a wax-based preservative for
protection against corrosion.
3.6 WATER BOX FLUSHING
(Special equipment)
Our truck-mounted concrete pumps can be
equipped with a pressure flushing of the water
box as special equipment.
With this device, the usual manual cleaning of
the water box is omitted to a large extent.
Four spraying nozzles in the top cover of the
water box rinse the inside of the water box and
piston rods of the differential cylinder.
Application:
- Open the drain cock 1 (Fig.: 22) of the
water box at the rear of the machine.
- Start the water pump and route pressurised
water to the spraying nozzles 3 of the water
box by switching the corresponding ball
valves 2 at the rear of the machine
- Start the concrete pump at a lower stroke
rate.
- Finish the cleaning process when clean
water emerges from the drain cock.
- Close the drain cock and fill the water box
with clean water.
This can also be done with the spraying nozzles
or, as usual, through the drain hose.
Always rinse the water box immediately after
each use of the concrete pump and check the
cleanliness at least once a week through visual
inspection.
