  • Patent number: 8430426
    Abstract: A cab suspension device for an agricultural tractor comprising a pair of concentrically aligned tubes co-axially arranged around a conventional cab suspension spring apparatus. One of the pair of tubes is connected to the tractor frame while the second is attached to the cab frame. The lengths of the tubes are shorter than the static length of the spring apparatus to allow limited telescoping movement of the tubes during dynamic compression of the spring apparatus without causing contact between the tube ends and the opposing tractor and cab frames. The dynamic extension during telescoping movement of the spring apparatus is controlled by a spring retainer. An annular space between the tubes allows for limited lateral displacement of the spring apparatus without causing contact between the tubes. The limits are configured to permit normal operational movement of the spring apparatus without contact of the tubes.

  • Patent number: 7950696
    Abstract: A roll-over protection system (1) for a vehicle (2), such as a quad bike. The system (1) comprises a telescopic hairpin-shaped roll-over guard (3), a lower mount (4) and an upper mount (5) for mounting the guard (3) to regions of the vehicle (2) that may move relative to each other. In use, the guard (3) extends upwardly from the vehicle (2) so as to prevent the vehicle (2) from remaining upside down after having turned over, and the mounts (4, 5) are moveable relative to the guard (3) when the two spaced apart regions move relative to each other during normal use of the vehicle (2).

  • Patent number: 7922201
    Abstract: The invention relates to a swivelable roll bar, in particular for construction vehicles, with two vertical carriers, each of which has a pair of spars, whereby in each, one spar is connected swivelably through a link joint with the another spar, and the link joint comprises a lock and a stop. The stop consists of a joint stiffener, which is built as an extension of one spar and partially grips about the end of the other. In addition to that, the lock has a continuously adjustable final control element, with which the joint stiffener can be braced against the other spar. With the grip about the other spar, the flexural strength of the link joint of the swivelable roll bar is increased. Further, the bracing of the joint stiffener against the other spar eliminates the play in the link joint. The joint stiffener is preferably built as a U-shaped tubular segment that is attached to the latter as an extension of the spar.
