Reinforced tractor cab structure - has sound roof panels on inside of hollow steel tube rectangular or polygonal sides frame

摘要

The tractor frame is assembled from hollow section steel tube, either rectangular or polygonal sided, with the broader sides parallel to the walls of the cab. The roll-over uprights as well as the transverse roof supports, are set on the outsides of the longitudinal frames with the wall panels set between them. The roll-over frames thus sit proud of the walls to protect them from damage. The walls are clad in sound proofing so that a strong, quiet cab design is achieved without increased cost and complexity.
