Drive and performance regulation
Concrete pumps are driven hydraulically. The necessary oil pressure is generated by adjustable hydraulic pumps driven by an engine through a gear box. The pumps are mounted in train fashion. The hydraulic system works in an open circuit.
An infinitely variable hydraulic valve controls the flow of concrete. The continuously variable adjustment of concrete conveying is effected through a hydraulic valve.
This hydraulic valve changes the oil conveying capacity and therefore changes the number of strokes to the requirements on job site.
The concrete pump conveying unit is mounted into a base frame in stable steel construction. This unit is designed for mounting on a appropriate chassis.
