Concrete pump truck

Concrete pump truck

Pumping concrete is the unit’s main job, and hydraulics help to get it done. But concrete placement only happens successfully if the truck is firmly planted on the ground. The boom may reach out 100 ft or more. To keep the unit from tipping, a set of outriggers reach out from the truck much further than on most cranes. These long-reach outriggers typically need telescopic cylinders to extend them and later to tuck them away. High quality, pilot-operated check valves keep the down-cylinders locked against the ground.

Product Description

Pumping concrete is the unit’s main job, and hydraulics help to get it done. But concrete placement only happens successfully if the truck is firmly planted on the ground. The boom may reach out 100 ft or more. To keep the unit from tipping, a set of outriggers reach out from the truck much further than on most cranes. These long-reach outriggers typically need telescopic cylinders to extend them and later to tuck them away. High quality, pilot-operated check valves keep the down-cylinders locked against the ground.

The operator’s remote pendant gives them control of the pumping rate described earlier, and also fine control of the various sections of the boom as well as swing motion. A separate open-loop piston pump is configured with a load-sensing (flow compensated) controller, which limits the pump to a pressure margin just higher than the most demanding boom function. The pump flow path for this circuit is open loop (tank to tank), but the control of flow rate and pressure is closed-loop. The load sense shuttle valve network inside the electro-proportional valve bank sends the highest function pressure back to the pump compensator/controller to make continuous adjustments. Pre-spool compensators in each section of the valve bank help to keep flow steady to lighter loaded boom cylinders already in motion, as the pump up-strokes in response to a heavier loaded boom section. This well-designed and tuned system gives the operator the ability to make smooth motions with the boom to move the placement hose to where it is needed during a pour, without wasting extra energy.

Performance Characteristics​

  • 1. High safety coefficient. Stepper motor imported from America and driver to control the engine speed.
  • 2. Choose the best quality materials. Import the 900# steel plate from Austria, Strength is three times than the 16Mn.
  • 3. More intelligent operation. The control system has the function of engine remote flame-out. You can start or stop the engine work according the working condition.
  • 4. High design standard. X leg, the car body is shot and the stability is good, the supporting leg can be unfolded out in a narrow space.
  • 5. International purchased component, which is with more high stability performance and high cost-efficiency.
  • 6. Pumping hydraulic system. Overall hydraulic commutation system; the alternative commutation actions between pumping and S tube distribution doesn’t involve electric signals, little impact and noise occurs during the commutation, so the service lives of hydraulic pump and valves are evidently lengthened.
  • 7. Intelligent control system. Adopt concentration plate to make the mail hydraulic system valve more concentration, reduce the pipeline road cross, save every drop of oil pump.
  • 8. Automatic control. Unique arm frame buffer technology can reduce the high pressure value system, even in the case of high output to make the boom steady;
  • 9. Efficient pumping. Large diameter cylinder, big pump flow;
