Crane support assembly
First Claim
1. A crane tower assembly comprising:
- a crane tower frame mountable atop at least two spaced apart horizontal support subassembly members for supporting the crane tower frame outboard relative to at least one longitudinally extending member of a vehicle frame, the at least two spaced apart horizontal support subassembly members configured for coupling with the at least one longitudinally extending member of the vehicle frame;
a horizontal arm coupled with the at least two spaced apart horizontal support subassembly members outboard relative to the at least one longitudinally extending member of the vehicle frame from beneath the at least two spaced apart horizontal support subassembly members and transversely relative to the at least two spaced apart horizontal support subassembly members;
a vertical support having a top end portion coupled with the horizontal arm and a bottom end portion couplable with an outrigger assembly; and
,a rigid brace extending angularly between the vertical support and the horizontal arm for supporting the horizontal arm and for transferring at least one of bending moment and shear acting on the horizontal arm during crane operation to the outrigger assembly via the vertical support.

Abstract
A crane support system includes two spaced apart longitudinal members couplable with a vehicle frame. Two spaced apart groups of tubes are coupled with and extend between the longitudinal members and outboard relative to one member to define an outboard subassembly portion. A tower frame is mounted atop the outboard subassembly portion. A first brace extends angularly between the groups of tubes, the brace extending from a one of the groups forward relative to the vehicle frame toward the other group aft relative to the vehicle frame and toward the tower frame. A horizontal arm extends transversely beneath the outboard subassembly portion. A vertical support has a top end coupled with the arm and a bottom end couplable with an outrigger. A second brace extends angularly between the vertical support and the arm for transferring bending moment and/or shear from the cantilever to the outrigger via the vertical support.
