There are two elements to the patented CAMBA technology that drives the HandiMoova – an Active Variable Footprint and the Floating Axle Suspension. CAMBA technology is simple and robust; there are no fancy mechanisms or high technologies involved. The technology constantly optimises the rolling performance of each wheel.
Active Variable Footprint
A sphere or ball adapts to whatever surface it is being rolled on. On a hard surface it uses just a small contact area and on a soft surface (sand for example), it uses a large contact area. If you were to cut the sphere or ball in half and mount each side on an inclined axle, there you have the principle of the CAMBA hemispherical wheel.
Like a ball, the footprint or surface area of the CAMBA wheel changes progressively and intuitively to whatever surface it is being rolled on. You have a low contact area for hard surfaces (like a bicycle wheel) and a large contact area for soft surfaces (such as a balloon tyre) – the best of both worlds. This makes CAMBA technology the perfect all-terrain wheel.
Floating Axle Suspension
By mounting the CAMBA wheels on a Floating Axle, you not only allow each wheel to move independently of the other, but also create the visual effect of the wheels both rolling and ‘walking’ over obstacles. This action allows the CAMBA wheels to ‘smooth’ out any bumps or rough terrain making it easier for the user to keep their load balanced on the CAMBA Moova without the risk of spilling, whilst reducing physical input. Please watch the following video to see the CAMBA wheels in action.
CAMBA wheels perform unlike any other wheel on steps and stairs. When going down a step, the force of gravity on the wheel and axle allows it to drop just milliseconds before the load. This keeps the load stable and the HandiMoova hand cart balanced. When the CAMBA wheels are pulled up against a step, they continue to rotate on the axle and in doing so create a less vertical and easier pulling angle for the user.
