The new S 38 SX combines a tight front outrigger spread, just under 23 feet, with a lightweight design and five-section boom exhibiting articulation capabilities exceeding other styles. Affording 107-ft. and 122-ft. horizontal and vertical reach, it is available in a three-axle configuration with cab-over truck or as a four-axle version with conventional truck to meet federal bridge laws.
“This pump defines versatility,” says Schwing America Senior Vice President of Sales and Marketing Tom O’Malley. “The new boom design hyper extends at every section to exceed the capabilities of Roll and Fold and Z Booms.” Among key S 38 SX boom features, he adds: All of the articulation is on the working side for faster deployment and the ability to snake the end hose deep into decks.
Front outriggers are the exclusive Super X style that telescope out and around jobsite obstructions. For tight set ups, the outriggers can be deployed on one-side only with the standard EASy system that narrows the footprint and provides up to 180 degrees of boom rotation on the pour side of the pump. The system is integrated into Schwing’s Vector Controls that monitor and ensure the safety of the pump and its operator. The system also provides proportional radio remote control of the boom function and communicates with the operator to stay fully informed of the pump’s status even when hundreds of feet from the pump.
The manufacturer’s open loop, twin-cylinder hydraulic pump is available in two sizes on the S 38 SX with output to 213 yd./hour. Both pump kits utilize the exclusive Rock Valve capable of pumping the harshest mixes and requiring limited water for clean up. The component’s long stroke and large diameter pumping cylinders reduce wear by achieving pumping volume with fewer strokes per minute. — Schwing America, St. Paul, Minn., 888/724-9464;
