Ruthmann’s T187AE allows more work to be completed with less repositioning compared to other access methods, and combines high reach with easy roadability.
Built on a Kenworth T480 chassis, the Ruthmann T187AE delivers a 187-foot working height and a 133-foot horizontal outreach, allowing crews to cover more area without repositioning. At around 60,000 pounds, the unit meets federal bridge law limits and can travel between sites without permitting. The dynamic reach system (DRS) calculates the working envelope in real time based on outrigger positions and platform capacity. Operators can select wind-speed ratings of 28, 35 or 43 miles per hour, and a jack-force limiter reduces ground-bearing pressure for sensitive surfaces.
For taller tasks, the Ruthmann T328AE raises the platform to 328 feet while maintaining the same 133-foot horizontal outreach. It shares the T187’s DRS envelope management and wind-speed/jack-force limiter options, giving crews enough vertical and horizontal reach to tackle work normally reserved for cranes or suspended access systems.
Ruthmann’s DRS technology optimizes each machine’s working envelope by analyzing outrigger position, boom configuration and platform capacity. Ruthmann’s working envelope adjusts in real time rather than relying on a fixed geometry, allowing reach to vary based on positioning.
Standardized components across the product line make maintenance simple. For contractors working on complex projects, these road-legal, high-reach platforms provide an alternative to traditional access methods and are used across sectors such as electric-utility linework, wind energy and telecommunications, among others.
