Road and rail vehicle with pivotable axle and associated methods

摘要

A road and rail vehicle includes a towing vehicle having a plurality of axles coupled to an elongate frame with road wheels disposed on the axles. The plurality of axles include at least one rear drive axle. Rail guide wheels are movably coupled to the frame. The rail guide wheels are movable between a lowered position engageable with a pair of fixed rails of a railroad track and a raised position away from the rails. A crane is coupled to the frame rearward of a rearmost road wheel. A tag axle is pivotally coupled to the frame rearward of the crane. The tag axle pivots between a lowered position that is engageable with a roadway and a raised position adjacent the crane.
