Lumede/Oliver BeckerThe Mamut forklift applies new conceptual thinking to the use of state-of-the-art technology. The basic idea is to separate the frame/wheel/motor unit from the lift/cabin unit. They remain connected via a spherical hinge, in such a way that the frame unit inclines in response to changes in the terrain, but the lift unit always remains in the vertical position to enable secure handling of the material.

For greater stability in rough terrain, the front wheels are attached to arms that can rotate from the front (effectively alongside the mast) to nearer the cab, providing more possibilities to find the most stable configuration. Two wheels together form one wheel unit, with each of the six wheels containing an electric wheel hub motor. There is no steering mechanism at all – this is achieved by letting the individual wheels of a wheel unit rotate at different speeds, or counter-rotate, as with crawler tracks. By doing so, the speed of the complete wheel unit can be finely adjusted.

The cabin is designed to be a security cell – a breakaway point beneath it will allow the whole unit to break loose from the frame and roll off in the unlikely event of a tip-over. To provide a better view while transporting the goods, the seat can be rotated 180°, so the driver has an open view to the rear. Easy access to the cabin is provided by gull-wing doors on either side. All information is projected in a head-up-display (HUD) to the front window. If the seat is turned, the HUD will follow and be projected to the rear window.
