S 45 SX

Truck-Mounted Concrete Pump with 4-Section Placing Boom

Separate yourself from the pack and become the leader in your market with these versatile pumps. You will gain more than 6-feet of boom reach with the optional S 45 SX which has a longer tip section. Both models share the same innovative Overhead Roll and Fold™™ boom design that works so well on bridges, commercial and industrial work.

Hundreds of pumpers and concrete contractors have discovered the versatility of a boom with a main section that articulates 180-degrees. This feature allows the main section to be angled away from the pour so that the boom can be guided horizontally into enclosed areas, positioned vertically to 151’3″ and stretched out up to 139’7″ over the cab for flatwork.

And whether you are reaching deep into a structure for a controlled pour or operating flatout on a deck, proportional boom controls let the operator maneuver the boom with confidence for efficient and precise placement utilizing an industry-leading 745-degrees of total boom articulation.

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.
