NVX Series capacity range is 38,000lbs to 85,000lbs tractive effort, single or double coupled. The Navigator Series is capable of moving up to 60 loaded railcars without weight transfer coupling. Spawned from the success of the more lengthy SWX840, launched in 2011, the Navigator Series includes (4) shorter models. Each Navigator model highlights the only mobile railcar movers in the business to utilize a pivoting drive axle and rail guidance system all in a single assembly. The system is very similar to the drive trucks on a locomotive which are allowed to pivot and turn along the rails. Product improvement focus includes enhanced rail stability, better performance in poor weather conditions, improved tire life and the ability to navigate up to 70 degree track curvature. The Navigator Series by Shuttlewagon is the pinnacle in mobile railcar moving. Shuttlewagon expands the railcar mover market, providing fresh alternatives to higher-cost-of-operation locomotive power by providing the only mobile railcar mover/shunting applications that exceed 35,000lbs tractive effort and do so with direct, non-weight transfer locomotive like coupling. The Navigator NVX9060 is the largest, highest capacity mobile railcar mover in the world, offering unparalleled pulling capability.
