Abstract
Systems and methods for a mobile crane are provided. In particular, systems and methods are provided for a mobile crane that is designed to enable easy transportation on a railcar to and from a job site. The mobile crane facilitates quick changing between a transport configuration and a work configuration to enable increased productivity. The mobile crane is configured to be modular and thereby be configured to include various lifting and object manipulating features, as required by a specific application.
Claims26
A crane apparatus comprising:
- a first truss assembly comprising a first main truss having a longitudinal axis, the first main truss being coupled to a first rail car end assembly;
- a second truss assembly comprising a second main truss spaced apart from and extending approximately parallel to the longitudinal axis, the second main truss being coupled to the first rail car end assembly, the first main truss and the second main truss spaced apart from one another to define an interior space;
- and
- an upper gantry assembly rotatably coupled to a first upper support beam of the first truss assembly and to a second upper support beam of the second truss assembly, the upper gantry assembly having a first bridge beam and a second bridge beam spaced apart from one another and extending across the interior space between the first truss assembly and the second truss assembly, the first bridge beam and second bridge beam being slidable parallel to the longitudinal axis within a guide track formed in the first upper support beam of the first truss assembly and a guide track formed in the second upper support beam of the second truss assembly.
