S 28 X
Here’s the boom size that started it all more than 30 years ago, now modernized for 21st century pumping. The new S 28 X combines four-sections with more articulation than any other 28-meter boom. And with 540-degrees of articulation in the last two sections, this boom gets you in places no other boom can.
Use your S 28 X to place inside enclosed structures or under bridge decks and mezzanines with low 19’2″ unfolding height. It also functions as a residential foundation pump with 78-feet of horizontal reach and performs on light commercial work with 91-feet of vertical reach. Fast, compact set-up with X-style outriggers and fast clean-out of the Rock Valve™ means multiple jobs per day including line pumping with the optional 180-degree discharge outlet.
Expand your market with this multi-duty pump that delivers as a specialty pump, goes out on everyday pours and fills in as a line pump. High utilization means high revenue when you match this pump up with lots of jobs every week.
Technology : Vector Control Systems
Now operators have valuable operational data at their fingertips because Vector is the first system to allow monitor-ing of the pumping process from the remote control box.
Technology : Rock Valve & Big Rock Valve
The revolutionary Rock Valve and the optional Big Rock Valve provide absolute reliability. The only completely rebuildable valves in the industry.
Technology : Generation 3 Concrete Pump Kits
The Generation 3 outperforms every other concrete pump on high visibility projects while also placing millions of yards of concrete on everyday pours.
