Preparation for travel
Store your clean-out rake, sponge ball, grease gun,
hammer, shovel, and all other accessories securely for
travel.
If the job was set up that you were keeping track of the
concrete delivery tickets, you should turn them over to
the concrete supervisor when you have him sign your
job ticket.
Before you get into the cab to drive, take a walk around
the trailer. Look for items that you may be forgetting,
look under the unit for personnel and obstructions, and
check for air pressure, tire pressure and wear, etc.
Many driving accidents happen on the way back to the
shop after a job, or on the way to a second job. Think
about your route, bearing in mind the time of day, road
construction, etc. As hard as it may be, you want to
begin driving with a fresh attitude and clear head.
NOTE!
If yo u r u nit is eq u i pp e d with hy d r au lic
st a bilizers, be s u re the f au cet va l v es a re
close d p rior to le av in g the job.
S pecial Pumping S ituation s
Rod s ide to pi s ton s ide pumping ( S P 2000)
The hydraulic system for the 900 and 1200 series
concrete pump can be configured for
ROD SIDE or
PISTON SIDE pumping, as shown in Figure 40.
Rod side pumping allows maximum yards per hour
output, while piston side pumping allows maximum
pressure to be exerted on the concrete. (See specific
instructions for pumping on piston side in the
Operation section of this manual). Piston side
operation dramatically raises the maximum pressure on
the concrete. For this reason it is crucial that your
entire material delivery system be rated to handle the
available pressure and kept in “like new” condition.
Remember that pipe wears with each yard pumped.
Inspect the wall thickness regularly. The maximum
material pressure available on
piston side depends on
which differential and material cylinders you
purchased with your unit and is stamped into the main
ID tag.
When configured on ROD SIDE, the hydraulic oil is
routed from the S2 valve to the differential cylinders at
the port on the rod end (the end from which the rod
protrudes). The rocking oil loop hose is connected
from one cylinder to the other on the piston end.
When configured on the PISTON SIDE, the hydraulic
oil is routed from the S2 valve to the differential
cylinders at the port that is on the piston end (the end
away from where the rod protrudes). The rocking oil
loop is connected from one cylinder to the other on the
rod end. Note that the rods are moving the same
direction in both examples shown, whether they are
configured for rod side or piston side pumping. This is
accomplished by crossing the lines from the S2 valve
as shown, and is necessary for the purpose of
maintaining the proper sequence of action so the
concrete valve is timed with the movement of the
differential cylinders.
