The successful, field-proven 42 m boom: now with the stabilizing system of the future.Coordination of load moment,structural weight and stabilizingwidth is a vital factor in large-boom truck-mounted concretepumps, determining onsitespace requirements. With con-ventional designs, the neces-sary effective spans of 8 m ormore are dependent on foldingoutriggers. Unfolding thesetakes up considerable space,
a commodity in short supply ontoday’s confined sites.With this in mind, SCHWINGhas now upgraded its success-ful, field-proven standard boom,the KVM 42, with the modernSX stabilizing system. Arc-shaped outriggers are locat-ed in longitudinal direction onthe vehicle frame, allowing
them to be longer. As they tele-scope on an orbital path, theyare extended laterally and for-ward simultaneously in thesame way as the linear X-stabi-lizer. The primary advantage is that the stabilizers are posi-tioned parallel to each otherand not one above the other aswith the linear X-stabilizer. Thisis the only means of achieving
effective spans of 8 m or more.This layout also makes way fora lower structural height, leav-ing room for the installation ofpump assemblies with an extralong stroke. That accounts forthe other name given to thisstabilizing system: the Super-X stabilizer, in briefthe “SX”.
The opportunity to install pumpassemblies with a high maxi-mum output of up to 163 m3/hoffers the owner special bene-fits with a low stroke rate dur-ing the concreting operation,meaning less wear, low fuel re-quirements, and a steady endhose during pumping. The heart of the concrete pumpis the Rock valve, a model of
pumping qualities, wear perfor-mance and operational de-pendability. The Rock valve and the integrated SCHWINGautomatic seal are patentedworldwide.The SX stabilizer has also al-lowed the entire superstructureto be completely redesigned. It is now characterized by its
streamlining, its generousstowage space for the pumpaccessories, and smooth,large-area panel-work. In prac-tice this means:working safety and efficient,fast cleaning of the entire su-perstructure. And even the unproblematic, operator-friend-ly 42 m placing boom with itssuccessful 4-section roll-and-
fold system excels itself withthis concept. A structural concept that willhave a major impact on the design of large-boom concretepumps for many years tocome.

Pump mechanics know thefeeling. In many cases the idealworking position just isn’t onthe cards with large-boompumps. Confined sites, fences,walls, trees and so on preventthe front outriggers from beingunfolded. Such site conditionscease to be a worst-case sce-nario with the SCHWING SXstabilizing system, thanks to
Long-stroke pump batteryIn addition to the obviousadvantages in outrigger tech-nology, our SX pattern hasmade it possible to build a reallong-stroke pump battery into aconcrete pump. At SCHWING, that means a battery with 2.5 mstroke!In such a battery, the sweptvolume of each concrete cylin-der is so large that the max.pumping volume of 163 m3/hcan be achieved with only 22 strokes.On every-day jobs, where theaverage output lies by roundabout 75 m3/h, the stroking ratedrops to an astonishing 12 per minute. And that meanscorrespondingly low wear costsper m3 of concrete pumped.
Technical harmony – the P 2525 H long-stroke batterycombined with the E-Rock.
Concrete flows from the 250 mmdiameter cylinders through thelengthened and widened Rockwithout any corners or bottle-necks and without energy-con-suming congestion.
The ROCKStandard, G-Rock or E-Rock?The standard Rock is the classic valve that stands for efficiency and economy in concrete pumping circles.
The G-Rock is the extendedversion of the standard Rockand is especially suitable fordifficult, stiff concrete mixes.The E-Rock is extended andwidened to become the idealcomplement for the long-strokebattery 2525 H with 250 mmconcrete cylinders. Carbidewear parts available on optionto provide even longer servicelives.
Radio remote control in combi-nation with proportional boomhydraulics for finger-tip easycontrol without overshooting.SCHWING MPS 2-circuithydraulics for concrete pumpensure quiet and fast shifting ofthe Rock and thereby keep theend hose nice and steady.
Loads of stowage room, fold-up steps, a lockable hopperhood, working lights and numerous safety devices in the CE version.
The standard version of a machine that has more to offerthan normal.
the telescoping front outriggers.This system not only makesfor short set-up times but canalso add decisively to theworking range of the placingboom.
After all, the closer you get,the greater the advantagesare!
The days are now past whereheavy slew/telescope outrig-gers took up not only room onthe jobsite, but also valuablespace on the concrete pump.One cylinder plus actuation foroutrigger slew. One cylinderplus actuation for telescoping.Two slider sections with theirfriction and wear areas. Andthat not to mention the weightconcerned!Now only one moving part isneeded – and therefore only one actuator. Even the hydraulic cylinder has disap-peared, to be replaced by alow maintenance high-performance cable pull.Naturally the multitude ofhoses, fittings and valves hasalso disappeared, along withthe tedious greasing of pinsand bushings.
The cylinder for the outriggerleg is fully protected inside its strong square tube. And thefoot plate is rigidly welded onto the extension tube toeliminate any risk of it slippingor of the cylinder rod gettingdamaged.Clearly visible in the sketch isthe strong, full-length twinframe that conducts all boomand pump reaction forcessafely into the outriggers andthen into the ground.The one-piece stabilizer arms(front and rear) achieve a fur-ther goal by eliminating themid-way telescope points thatlead to undesirable machine“bounce”.The rear right-hand outrigger ispurpose designed as a watertank. The rear left arm can beequipped as a booster tank fordiesel fuel (optional).
S 42 SX: large boom pump with no folding outriggers at the front. Only 8.3 m stabilizing width.
