The SP 1400 - “A SCHWING solution for high delivery volume with low concrete pressure , low delivery volume with high concrete pressures & high fuel efficiency in the compact-class with 48 kW engine power. Therefore the SP 1400 is designed with a whole row of excellent features in usual SCHWING quality. As on all SCHWING concrete pumps , the SP 1400 has an output-governed hydraulic pump that ensures that the prime mover is never over loaded, 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 negligible output losses and minimum stress for the hydraulic components.
During shor the main control spool is shifted to “idle circuit” so that all of the oil coming from breaks in pumpin hydraulic pump flows pressur the back to the tank, thereby making a fur ther contribution towards keeping oil temperatures low. On SCHWING pumps, there is no feed pump that runs on continually and turns valuable energy into wasteful heat.
The hydraulic control system is integrated within the drive. The compact Control block & minimal hydraulic lines makes the equipment Reliable & durable.
Direct high- torque driven on to the agitator shaft as well as robust design of all hydraulic components in conjunction with constant flow micro-filtering of the hydraulicoile nsure operational reliability and a long service life.
A central bank of grease nipples supplies grease to all of the lube points on agitator and rock valve.
Compact design individual switching circuit ensures quick operation of rock valve.
The SP 1400 comes complete with a 10m cable remote control as a standard feature.
Normal Rock or RL-Rock? Among concrete valves, the normal rock valve is the classic known all over the world. For more than 20 years, it has been the paragon of power and reliability. It is patented in practically all industrialized countries it offers exemplary pumping characteristics, wearing proper ties and operational safety.
RL– Rock Valve, is a new generation Rock Valve, Engineered by SCHWING R&D after extensive study of behaviour 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.
