<p>FALLING OBJECT PROTECTIVE STRUCTURE A falling object protective structure to protect the operator's cab of a hydraulic excavator or the like includes a canopy assembly mounted over the roof of the operator's cab which projects forward of the cab structure. The canopy is mounted on the cab structure at the front of the cab by resilient means, whereby bending moments imparted to the canopy assembly by the impact of falling objects will not be transmitted to the cab structure. The protective structure is mounted directly to the top of the cab on the vertical support members inherent in the cab structure.</p> |
