DEVICE FOR THE LATERAL DISPLACEMENT OF A DRILLING/RAMMING TOOL POSITIONED ON A RAILWAY WAGON HAVING A LOADING AREA AND METHOD FOR MAKING FOUNDATION RECESSES WITH THE AID OF THE DEVICE

摘要

A device (14) for lateral displacement of a drilling / ramming device (16) positioned on a railway wagon (10) with loading area (12) for making foundation recesses in the ground (92) next to a track is provided with a laterally movable device Platform (32) on which the drilling / ramming device (16) can be positioned, the platform (32) having two lateral edges (30, 34) facing away from one another. The platform (32) is carried by a support unit (40) with at least one automatically extendable and retractable widening element (36) which in an extended position protrudes laterally beyond one of the lateral edges (30, 34) of the platform (32) and in a retracted position is set back from the pull-out position. The at least one widening element (36) has at least one extendable support element (38) which can be transferred from a rest position to a support position for supporting the at least one widening element (36) on a substrate (92). The platform (32) can automatically be moved laterally on the at least one widening element (36) in the pull-out position.
