Abstract
Cab assemblies utilized on modern day construction vehicles normally include a myriad of sheet metal components that are welded or bolted together to provide the structural support and the mountings for the various components that comprise a cab. The number of components and the time required to fabricate and weld, or otherwise assemble them, is often quite extensive. The more piece-parts that are required in the configuration of a cab, the more time is required to complete the assembly process. This translates directly into the cost of a cab assembly. The present invention provides a cab assembly that utilizes a non-metallic floor member as an integral part of its structure. The floor member not only incorporates the hardware required for mounting various components housed within the cab assembly, it also provides support for the cab'"'"'s windshield assembly. The windshield assembly is mounted between the floor member and a structural member positioned in the vicinity of the cab'"'"'s roof. Both structural members are adapted to provide surfaces to which the windshield assembly may be bonded. The combined result of these features provides a cab assembly that has a greatly reduced number of components and is therefore extremely economical and efficient in its design.
