SCHWING portable concrete pumps are successfully deployed worldwide wherever vast quantities of concrete have to be pumped over exceptionally long horizontal and vertical distances. In building and civil engineering projects, they are also fast, reliable and economically efficient in handling pumpable concretes under extreme conditions with regard to concrete designs, job sites, and climate. Compact class, High performance & High fuel efficiency The Rock Valve RL-Rock valve, is a new generation Rock valve, Engineered by SCHWING R&D after extensive studies of behavior of tough concrete in various developing countries. This rugged, reliable rock valve is highly suited for stiff, difficult mixes of concrete and ideal for use in combination with the long stroke pumping unit. An option that can be recommended is the hard facing layer for extremely long service life. Integrated Control Block The hydraulic control system is integrated within the drive. The compact control block & minimal hydraulic lines makes the equipment Reliable & durable. Fast Switching Valve Compact design individual switching circuit ensures quick operation of rock valve. Remote Control The Concrete pump comes complete with a 10-meter cable remote control as a standard feature. Hydraulics All SCHWING concrete pumps have an output governed hydraulic pump that ensures that the prime mover is never overloaded, the automatic governor splits available engine output optimally into oil flow and oil pressure and allows the concrete pump to run at the best possible output level. At the same time, the manual de-stroker valve can be used to set the pump to a required fine tuning to set stroke rate and output independent of the automatic governor. The open circuit, combined with the SCHWING designed “Hi-flow” spool block ensures minimum heat generation in the hydraulics, therefore there are negligible output losses and minimum stress on the hydraulic components. Pumping The pump has two powerful differential and pumping cylinders. The prodigious combined capacity and performance of these cylinder systems ensures a high output. Our pumps are designed to offer you maximum output with minimum number of strokes to increase the life of the cylinders.

The motor (Diesel or Electric) drives the axial piston pump via a flexible coupling. Due to automatic output adjustment optimum utilization of the motor power, resulting in low energy consumption at differing pumping condition. Additionally, the concrete flow can be manually adjusted. The pump operates in a proven open circuit.The maximum placing output and the pressure are determined by the construction sites. Between these two values, automatic adjustment by the governor occurs maintaining a constant output depending on the power available from the installed drive motor. Design The portable concrete pumps are assembled in the unit construction system. The main assembly groups are Frame, Power unit, Concrete pump kit, Control block, Hydraulic tank and Hopper with agitator. The Frame & Axle The frame, in compact execution, is constructed from standard vehicle profiles. The pump is mounted on heavy duty single axle chassis with draw bar, pneumatic tyres and for travelling on construction sites at up to 25 km/hr. Control System The fully hydraulic control system is integrated within the drive. The compact control block and minimal hydraulic lines makes the equipment reliable and durable. The differential cylinder has trouble free piston rings and automatic constant stroke maintenance. Both gate valves change independently so that even when full change over is prevented by foreign material or similar obstructions in the concrete, the pump continues to operate without problems. All components are especially developed and manufactured to withstand the rough treatment on construction sites.
