SAFETY
Everyone involved with the operation, maintenance, inspection, and repair of the
concrete pump MUST READ and UNDERSTANDS this manual and the
accompanying Safety Manual.
SAFETY ALERT SYMBOLS AND SIGNAL WORDS
The following safety alert symbols, signals, and explanations are intended to warn the
operator of hazardous and potentially hazardous situations.
The triangle with the exclamation point inside is used to alert the operator to an important
safety point, and is called a safety alert symbol. One of the following signal words will
appear after the safety alert symbol:
If the safety alert symbol is followed by the signal word DANGER, the safety alert
symbol indicates a hazardous situation which, if not avoided, WILL lead to death or
serious injury.
If the safety alert symbol is followed by the signal word WARNING, the safety alert
symbol indicates a potentially hazardous situation which, if not avoided, COULD result
in death or serious injury.
If the safety alert symbol is followed by the signal word CAUTION, the safety alert
symbol indicates a potentially hazardous situation which, if not avoided, COULD result
in minor to moderate injury.
The signal word CAUTION, but without safety alert symbol means the safety symbol alert
addresses a hazard which, if not avoided, COULD cause damage to equipment or
property.

PRODUCT DESCRIPTION
The operation of the concrete pump encompasses the use of hydraulic and electrical
systems. The concrete pump is designed to safely pump wet concrete through a delivery
system of pipes and hoses within its published ratings and specifications.
Stability of the concrete pump during operation is provided by the outriggers and front
jack. Controls for the outriggers are located on the sides of the concrete pump.
The pumping system employs an S-Tube design valve system. This system incorporates
material cylinders linked to hydraulic cylinders that cycle alternately. With concrete
material in the hopper and the pump operating, a material cylinder retracts, drawing
material into the cylinder. At full retraction of the cylinder, a signal is sent to both the S-
tube swing cylinder and the drive cylinder directional valves causing the s-tube to shift
position to the fully loaded material cylinder and the drive cylinders to change direction.
The concrete piston of the loaded cylinder then pushes the material through the s-tube
and into the delivery lines. The shifting from one cylinder to the other cylinder takes place
providing a continuous flow of material through the delivery piping system. The pump can
be operated at the control panel or can be operated from the remote control.
The hydraulic oil flow created by the hydraulic pump pushes the drive cylinder pistons
inside the drive cylinders (1) alternately back and forth. Because the drive cylinders and
concrete pistons (2) inside the concrete cylinders (3) are linked together, the pistons move
synchronously.
When a drive cylinder retracts along with the concrete piston, concrete will be sucked
from the hopper into the concrete cylinder. Simultaneously, the other drive cylinder and
concrete piston are extended toward the hopper. The concrete piston will push concrete
from the concrete cylinders through the S-Tube (4) and out to delivery system (5).
Next, the pump switches at the end of the stroke, causing the s-tube valve to shift to the
other concrete cylinder which has sucked and filled the cylinder with concrete, starting
the next cycle.
Reverse pumping links the concrete piston in the suction stroke and S-Tube valve to suck
concrete from the s-tube instead of the hopper. As a result, the concrete piston pumps
concrete into the hopper.

The power for operation of the concrete pump is provided by the engine, which drives the
hydraulic pumps.
All functions for operation of the concrete pump can be accomplished from the local
controls mounted on the side of the unit. Optional hand-held cable or radio remotes
enable the pump to be operated away from a remote distance.
HYDRAULIC SYSTEM DESCRIPTION
The hydraulic system of the concrete pump consists of three separate circuits and
although integrated, each is designed to perform a particular function within the
operation of the concrete pump. The three circuits utilized are:
•Main Pump Circuit
Controls operation of the hydraulic drive cylinders.
•S-Tube Shift Circuit
Controls operation of shifting the s-tube from one material cylinder to the other.
•Auxiliary Circuit
Controls the operation of the agitator and other auxiliary equipment.
For the purpose of making the operation of each circuit easier to understand, they are
being described separately.
MAIN PUMP CIRCUIT
The main hydraulic pump is a variable displacement axial piston pump of swashplate
design. The pistons run along the swashplate which is capable of being tilted. This tilting
changes the angle of the swashplate and thus the stroke length of the pistons, which in
turn varies the displacement of fluid. The larger the angle of the swashplate, the greater
the flow. The angle of the swashplate is varied by the volume control that works in
conjunction with the load sense feature of this pump.
The main hydraulic pump is driven directly by the engine or electric motor. When the
engine is running, PUMP switch in the OFF position and the VOLUME control minimized,
there is no demand placed on the pump. This is referred to as the pump being de-stroked,
meaning, it is only producing a minimal amount of flow to enable the lubrication of the
pump. This lubrication exists regardless of whether the engine is at idle or maximum RPM.
The main pump circuit is equipped with a manifold that is drilled and ported to
accommodate the relief valve, check valve, flow control and the pilot operated directional
valve. The cycle valve is a directional spool valve with electro hydraulic solenoid
operation. Its purpose is to direct the flow of oil from the main hydraulic pump to one or
