LS600 PUMP — PUMP COMPONENTS
Figure 5 illustrates the location of the major components
for the LS600 Concrete Pump. The function of each
component is described below:
1. Tow Hitch Coupler – Requires a 2-inch ball hitch or a
3-inch pintle. Capable of towing 6,000 lbs.
2. Documentation Box – Contains engine and pump
operation, parts and maintenance information.
3. Manifold Access Door– Release latch and lift door
to access the Hydraulic Manifold Block.
4. Hydraulic Manifold Block – Manifold block that
controls the flow of hydraulic pressure to the
components required to control the pump.
5. Hopper Discharge Sleeve – Connect hoses or steel
pipes to the discharge sleeve for pouring concrete.
6. Pump End Jack Stand – Use this jack stand to level
and support the rear end of the pump. NEVER deploy
on un-level ground and always check for firmness of
ground.
7. Shuttle Cylinder – Under pressure, the shuttle
cylinder shears concrete passing from the concrete
cylinder to the delivery line during the cycle phase.
8. Tires — This trailer uses two ST205-750 x15E type
tires. Tire inflation pressure is the most important
factor in tire life. Pressure should be checked to
50
psi cold
before operation. DO NOT bleed air from
tires when they are hot. Check inflation pressure
weekly during use to insure the maximum tire life and
tread wear.
9. Battery – This unit uses a +12 VDC type battery.
ALWAYS use gloves and eye protection when handling
the battery.
10. Hydraulic Pump – This unit incorporates an axial
variable displacement hydraulic piston pump.
11. Heat Exchanger – Reduces temperature of the
hydraulic oil. The exchanger draws oil from the hydraulic
tank through a filter and into the heat exchanger before
allowing it to flow into the hydraulic system.
12. Accumulator – Stores hydraulic oil under pressure
and releases it to the shuttle cylinder and provides
the pressure needed to ensure enough force is
provided during cycle.
13. Remixer Control Lever – Controls the forward/reverse
motion of the hopper remixer paddles.
14. Hydraulic Oil Sight Glass – Use to determine the
amount of hydraulic oil remaining in tank. The sight
glass also contains a temperature gauge for monitoring
the temperature of the hydraulic oil.
15. Hydraulic Oil Tank/Cap– Remove cap to add
hydraulic fluid. Fill with Shell Oil Tellus 68 or Mobil Oil
DFE26 if level is low.
16. Accumulator Pressure Gauge– Used to monitor
accumulator pressure. Pressure should read at least
1750 psi for correct pump operation.
17. Pumping Pressure Gauge – Used to monitor
pressure in the concrete cylinders and shuttle tube.
18. Control Box – Contains the electrical components
required to run the pump. See Control Box Components
section for component callouts.
19. Fuel Tank/Cap – Fill with diesel fuel. Fuel tank (cell)
holds approximately 40 gallons (176 liters). DO NOT
top off fuel. Wipe up any spilled fuel immediately.
20. Hydraulic Oil Filter – This in-tank return hydraulic
filter with a 10 micron cleanable filter is designed to
remove all particles large enough to cause wear and
job break down. Under normal conditions, replace every
6 months.
21 Lubrication Box – This box is empty when shipped
from the factory. Please fill with 3 gallons (11.35 liters)
of SAE 30 motor oil for first time use. Also check the
dual clean-out point on bottom of lubrication box for a
secure tight fit.
22. Rear Running Lights – ALWAYS check and make
sure both the right and left running lights are functioning
correctly before towing the pump.
23. Remixer Motor – Drives the remixer paddles inside
the hopper. The motor direction is controlled by the
remixer control lever.
24. Hopper/Hood – Lift hood to fill. Concrete from a Redi-
Mix truck is poured into this hopper. The hopper can
hold 10 cu. ft of concrete with optional forward/reverse
mixer. NEVER put hands or any other parts of you
body into the hopper.
25. Tow End Jack Stand – Use this jack stand to level
and support the tow end of the pump.
