Method, Apparatus and System for Lifting Railroad Structures
A system and method for use in raising the height of railroad structures. Railroad structures are defined as the structures where two or mor railway tracks merge, cross, or divide. The method utilizes excavating an opening beneath a railway track at or adjacent to a railroad structure. A hydraulic jack is positioned within the opening. This is repeated until sufficient hydraulic jacks have been positioned around the structure. The hydraulic jacks are then actuated to raise the railroad structure to a desired height. Generally this height provides a slight crown to the structure. Ballast is then positioned beneath the raised railway. The hydraulic jacks can be disconnected from the hydraulic lines and left in position, or removed. Preferably the hydraulic jacks are positioned on hydraulic jack sleds for improved ease in transporting the hydraulic jacks and to provide a platform on which the hydraulic jack is slid into and out of the opening beneath the railway. An apparatus is provided for use in raising a railroad structure. The apparatus utilizes a hydraulic pump and motor positioned on a frame. Hydraulic fluid is selectively provided through a manifold to the hydraulic jacks, or to one or more remote manifold(s) either directly or through the manifold. Hydraulic jack sleds are provided that are preferably configured for storage and transport on the frame.
Road rail stoneblower
The present disclosure generally relates to a road rail stoneblower vehicle for carrying out rail maintenance operations near fixed structures such as bridges and overpasses. The road rail stoneblower includes a hi-rail chassis having a first set of wheels configured to engage a road surface and a second set of wheels configured to engage surfaces of substantially parallel rails of a railroad track. The road rail stoneblower further includes a plurality of workheads that are capable of dispensing ballast stones into a bed of ballast underlying the railroad track to adjust the height of the rails. The road rail stoneblower further includes a leveling system detachedly coupled to the hi-rail chassis that is configured to transmit a detectable signal that defines a reference plane with which the rails are to be aligned. Related methods of operation of the road rail stoneblower vehicle and associated maintenance of ballast beds underlying railroad tracks are also described.
