US 4,050,735 A · Multi-purpose cab for construction vehicles

Abstract

A basic cab unit, mounted on the frame of a construction vehicle such as a wheel loader, comprises a substantially flat rear panel having a generally rectangular opening formed therethrough. The opening is defined by a plurality of mounting flanges adapted to have the mounting flanges of a window unit secured thereto. In a first embodiment of this invention the window unit, having mounting flanges extending outwardly therefrom, is secured to the mounting flanges of the basic cab unit along with flanges formed on a roll-over protection structure (ROPS). The latter structure further comprises a reinforced canopy which extends over a top panel of the basic cab unit. In a second embodiment of this invention a window unit constitutes the sole component secured to the basic cab unit by flanges formed thereon to extend inwardly towards each other.
