Construction plant with two methods of locomotion - has caterpillar tracks and hydraulic supports to allow plant to position itself on and off railway tracks

摘要

The construction plant, such as a pile driver, is operated from platform (1) which is located on a self-propelled tracked (3,4) vehicle. Hydraulically operated outriggers (5,6,7,8) provide support when deployed, and also take the weight of the equipment when it is moved laterally to its longitudinal axis, ie when it is being positioned on a rail track. USE/ADVANTAGE - Plant can be driven to railway track and then onto and along the track itself and can thus be used in situations inaccessible to conventional road plant.
