| 摘要 |
A system for over-the-road hauling of track laying equipment, such as cranes, wherein hoist and/or counterweight components of the equipment are used to elevate the tracks away from ground contact for suspension between a wheeled trailer and a conventional tractor. While the equipment is suspended, the tracks may be retracted to minimize the over-the-road width, or tracks of increased ground contacting area may be laterally extended for improved stability and/or maneuverability at times of use.
