Abstract

A tire trolley assembly comprises a frame having a pair of supports including a first and a second support extending between a first and a second end. A connector is disposed at the first and the second end, attached to the support, extending between a primary end adjacent to the frame and a secondary end spaced from the frame. A plurality of wheels includes a first and a second wheel attached to the connector. A plurality of mounting members, including a first mounting member rotatably attached to the first wheel and coupled to the connector and a second mounting member rotatably attached to the second wheel and coupled to the connector. A traveling control system controls and steers the wheels of the tire trolley assembly.

Abstract

A lifter assembly includes a base having a top and a bottom surface. Connectors are attached to the base extending outwardly from the bottom surface. Each of the connectors includes at least one rail wheel rotatably attached thereto. The base includes traveling wheels rotatably attached thereto. A post is attached to the base extending outwardly from the top surface to a distal end. An arm is disposed on the distal end, rotatably attached to the post, extending outwardly to a terminal end. A support is movably attached to the arm and extends outwardly to a support end. A trolley is slidably disposed on the arm and movable along the arm between the terminal end and the post. Each of the traveling wheels includes a leg pivotably attached to the base connecting the traveling wheel to the base and move the traveling wheel between a transport and a storage position.

Abstract

A gantry assembly includes a main beam extending between a first and a second end. A plurality of legs including a pair of first legs and a pair of second legs attached to the main beam. A pair of first trolleys is slidably attached to the main beam. A first girder is attached to each one of the first trolleys and extends outwardly from the first trolleys for movement with the first trolleys. The first girder includes a pair of posts having a first and a second post disposed spaced from one another. The first post is attached to the first girder and extends downwardly from the first girder. The second post is slidably attached to the first girder and is movable along the first girder toward and away from the main beam allowing the gantry assembly to have different widths to accommodate for a single or double railway bridge.
