5-Section XT Telescoping Boom

This 5-section boom provides versatility that is really two machines in one. In low overhead situations the boom needs only 18’-8” unfolding clearance opening up jobs that are unavailable to other pumps.  

Generation 3 Pump Kit

Outperforms every other concrete pump on high visibility projects while also placing millions of yards on everyday pours.  

Vector Controls

Valuable operational data at your fingertips to allow monitoring of the pumping process from the remote control box.  

Rock Valve™

No other sequencing valve combines lowest cost per yard maintenance costs and ease of rebuilding as the Rock Valve™.
Gary Brown, Operations Manager for R.L. McCoy, calls his three Schwing S 31 XT concrete pumps with five-section telescopic booms "real breadwinners" because of their high utilization. With low 18'8" unfolding height, the 31-meter can work inside in the industrial areas of Indianapolis where re-tooling of automotive plants is common. "Customers ask for it," according to Gary, and when his 31s are not doing specialty work, they can be used on residential and light commercial work. "They stay busy," Gary says, "I bought my second one within three months of buying my first. There have been a couple of weeks when I could have used six of them." -Gary Brown, Operations Manager for R.L. McCoy
