Abstract
Abstract A vehicle cab and a safety frame are constructed as separate units. The safety frame is rigidly fixed to the vehicle frame and the cab is secured to the safety frame by resilient mount assemblies which isolate the cab from the ordinary flections and vibrations of the safety frame. Four resilient mount assemblies are used to suspend substantially the entire weight of the cab from upper structural members of the safety frame and a pair of resilient mounts are used to anchor the cab to lower structural members of the safety frame. The upper and lower resilient mount assemblies cooperate to limit lateral and fore-and-aft movements of the cab.
