ABSTRACT:
A cab for rollover protection of a driver of a large off-road machine in which the machine has a frame with a longitudinal axis in the direction of normal travel, the cab being formed of a superstructure of a generally rectangular box configuration, one lower edge of the cab superstructure being pivotally affixed to the machine frame about an axis of pivotation substantially parallel to the vehicle frame longitudinal axis and a limited displacement shock absorber attaching the cab superstructure other edge to the machine frame so that thereby in the event of rollover of the vehicle, the shock absorber absorbs energy to reduce the possibility of collapse of the superstructure to thereby provide increase safety to the machine operator.
The cab may be formed of a superstructure with a modular system including a control instrument module removably attached to the superstructure front, an environment control module removable attachable to the superstructure back, and left and right door modules removaly attachable to the superstructure left and right sides, whereby the modules may be separately manufactured and removable for repair without removing the entire cab superstructure.
