Has anyone ever seen a Western Star like this before? What you’re looking at is a concrete pumper on a conventional chassis. It’s usually set up on a Mack cab over, but the folks at Schwing Concrete Pumpers have come up with a new design… and it sure is sweet!
This Western Star 4700SB gets its grunt from a DD13 engine, 410 HP small block Allison 4500 RDS transmission, 20K DDC front axle, 46K Meritor rears, and all tied together with ½” single rail over a 294” wheelbase. The 13 gal def tank with the 60 gal fuel, and the understep exhaust packages are perfect with this pumper set-up!
Thanks to Ron Donze, from Truck Centers in Troy, IL, for sharing this awesome truck!
