  • Cab-over-engine vehicle with a non-tippable cab
    Patent number: 6817433
    Abstract: Cab-over-engine freight vehicle with a driver's cab which is untiltable relative to the chassis and is situated above the vehicle's engine which is supported by the chassis. On each side of the vehicle there is a panel which is provided with steps, delineates the engine compartment laterally and is mounted pivotably on the chassis by means of a panel control arrangement which makes it possible to impart a displacement movement to the panel so that it swings outwards and rearwards in the longitudinal direction of the vehicle to an engine access position. Below the door of the driver's cab there is a cover which is hinged-mounted on the chassis and which in the closed position conceals the step panel situated inside it. The cab door and the cover below the door are detachably coupled with one another by a relative-motion absorbing control arrangement.

  • Load carrying arrangement for a vehicle
    Patent number: 6641206
    Abstract: A loadbearing structure for heavy vehicles, e.g. a freight vehicle, incorporates a box-shaped hollow unit (10) extending in the longitudinal direction of the vehicle. Wall elements (12, 14, 16, 18) of thin wall thickness are connected to one another to form the box-shaped unit (10). The invention provides a loadbearing structure (2) for heavy vehicles which is many times more rigid than conventional structures but is nevertheless of relatively low weight and is relatively easy and inexpensive to manufacture. The present invention also relates to a process for manufacturing a loadbearing structure for heavy vehicles.

  • Cover for a vehicle
    Patent number: 6375248
    Abstract: A side curtain for the superstructure of a freight vehicle has its upper edge arranged for longitudinal movement at an upper portion of the superstructure. The bottom edge of the curtain includes a relatively rigid engaging device which extends along substantially the whole length of the curtain, is releasably connectable to a tensioning device. The engaging device has evenly spaced bending notches which, when the engaging device is at least partially freed from the tensioning device, guides the folding of the curtain during movement of its upper edge towards a non-covering position.
