A-30 Under Bridge Unit

The Aspen Aerials A-30 has a 30’11” maximum horizontal reach under the bridge.  The truck is ideal for smaller bridges, tight trusses, or bridges with little clearance under the deck.

The A-30 is the only under bridge truck with hi-rail capability and it easily maneuvers from road to rail at any at-grade crossing. Road to Rail capable equipment allows access to any location with railroad tracks with a quick and safe transition.

The front guide wheel assembly attaches to the frame and front axle and lifts the front wheels off the track, thus utilizing the vehicle’s front suspension. This design supports the vehicle as it was intended and helps the truck navigate curves smoothly and damp out the effects of track irregularities. The rear assembly attaches directly to the truck frame behind the rear axle.
