Abstract An articulated vehicle includes front and rear main frame sections having cooperating parts defining a vertical pivot assembly. A boom structure is mounted on the front frame section adjacent the pivot assembly and includes a lower boom section mounted for slewing about a vertical axis. The lower boom section includes an elevated portion which is offset from the vertical axis so as to trace a path which passes generally vertically above the pivot assembly when the boom section is rotated. A cab is mounted on the rear frame section adjacent the vertical pivot assembly and includes a lower forward portion which houses an environmental control unit and projects forwardly to a location above the pivot assembly and beneath the path traced by the offset portion of the lower boom section during rotation of the latter.
In an articulated vehicle of the type including first and second frame sections pivotally interconnected by a vertical hinge structure, a boom support structure mounted on the first frame for rotation about a vertical axis located adjacent the hinge structure and including an elevated portion offset laterally from the vertical axis and located to trace an arcuate path extending directly above said hinge structure, and a cab mounted on the second frame section adjacent the hinge structure, the improvement comprising: said cab including a lower housing portion extending directly above said hinge structure at a level below said arcuate path and having at least a portion thereof located directly below a portion of said elevated portion of the boom support when the portion of the elevated portion is located directly above said hinge structure and cab environment control elements being located in said lower housing portion.
