•
Keep a sufficient distance away from slopes, pits, trenches and excavations that
could breakaway.
•
Make every attempt to set up as near as possible to placement site. The shorter the
pumping distance the greater the material delivery.
When the site for the operation has been selected proceed to set up unit for pumping.
•
Disconnect safety chain, electrical cable and hitch from towing vehicle.
DELIVERY SYSTEM SUGGESTIONS
The delivery system is an arrangement of those components used from the pump
discharge to the placement site. This could consist of rubberized material hose, steel
piping, clamps, couplers and reducers. How this delivery system is set up, what
components are used will greatly affect the end result of efficient and productive concrete
pumping. The following suggestions are offered to assist in achieving your objective and
for your consideration in laying out the delivery line.
•
Use the most direct line as is feasible from the concrete pump to the placement area.
•
Set up the delivery line using a minimum of rubber hose. Rubber hose offers three
(3) times the resistance to the flow of concrete as compared to steel pipe.
•
Concrete will also flow with less back-pressure through pipe than through hose.
•
Minimize the use of bends in the hose. This requires more pumping pressure.
•
Place the hoses or pipe to the farthest placement point from the hopper discharge
outlet FIRST. It is easier to remove lines than it is to add as the pumping operation
takes place.
•
The steel pipe, elbows, and reducers and hoses should be equipped with heavy-duty
ends. These ends have a higher-pressure capability than the standard ends.
•
Only connect together couplings or clamps that are clean and seals that will retain the
slurry in the delivery line. Dirty couplings LEAK and when pressurized the leaking of
water will inevitably cause blockage.
•
DO NOT USE any worn or damaged hoses, pipes or couplings.
