Symmetrical Switching

All Schwing concrete pumps come standard with Symmetrical Switching, which provides faster switching of the Rock Valve, for a smoother and quieter operation. While Symmetrical Switching is great for everyday pumping, the benefits are greater when pumping stiff mixes that generate higher concrete pressures, particularly when pumping high-rise buildings.

In operation, both switching points are at the water box end of the differential cylinders allowing oil to feed evenly into the bridge hose on both switch points. Symmetrical Switching also allows for easier Ram change because the right-hand material cylinder retracts completely, even when plumbed on the piston side.
