4-Section Roll and Fold®

The original and for many contractors the best all around boom type for fast unfolding, easy cleanout and precision placement.    

Optional Detachable Boom

detachable boom option that allows the boom to be easily removed and mounted hundreds of feet from the pump.    

Super X Outriggers

Incorporates Schwing’s exclusive Super X Outriggers® that set-up fast and provide a compact and stable platform for pumping.    

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™.    

Optional Tremie Boom

A special tip section allows the S 39 SX to accommodate up to a 45-foot tremie pipe providing the pipe’s wall thickness is not more than .125-inches. This option eliminates the need to support the tremie with a crane while pumping.
