Abstract
Aspects of the disclosure relate to an apparatus having a travel height truss including a frame suitable for transporting an item. The apparatus includes a boom which may be raised from the frame. The boom is raised and lowered by a hydraulic system comprising a travel height truss. The travel height truss may comprise two portions, telescopically connected to each other, one portion pivotably connected to the frame and the other pivotably connected to the boom. The travel height truss provides greater leverage than would otherwise be available for the maximum size and weight of the load available for a given (fixed) maximum length of trailer. In this manner, the boom frame can be raised to greater heights, while maintaining horizontal distance, than otherwise.
