Overall the Tallwrapper Vertex is a robust machine as it is evident just looking at it. Every detail has been thought to ensure an undisputable reliability. Examples are: the central mechanism of rotation, that has been many times oversized with respect to the load that is has to bear, the frame toughness, the ascent-decent carriage column rigidity, the choice of components from the best manufactures. The Tallwrapper Vertex is the right solution.
