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.
The Concrete pump comes complete with a 10-meter cable remote control as a standard feature.
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.
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.
