6. A folding rollover protection system, comprising:
-
an upper ROPS tube pivotably mounted to a lower ROPS tube, each of the upper and the lower ROPS tubes having a pair of ends; a pair of hinge assemblies provided between the lower ROPS tube and the upper ROPS tube adjacent the ends, each hinge assembly including a pair of hinge plates welded to the lower ROPS tube with a gap between the pair of plates for the upper ROPS tube to slide therebetween and pivot between the raised or upright position and the lowered or folded down position; a pivot member extending transversely between each pair of plates and providing an axis on which the upper ROPS tube can pivot between the upright and folded down positions; and a vibration dampener positioned on a plate substantially covering the end of at least one of the ROPS tubes, each vibration dampener made of resilient material that is compressible and has a hollow center portion, the dampener being compressed between the ends of the upper and lower ROPS tubes if the upper ROPS tube is in the upright position. - View Dependent Claims (7, 8)
