This is "vertical tandem parking", at very, very low cost. Whether you need additional parking spaces, reduction in the car park area (no basement) or simply to give your building the edge over the competition by offering more parking spaces per tenancy or to meet council requirements? The VA2ST 2.1 weight capacity of 2,100kg could well be the answer. It can also be retro fitted within the building, or externally. Using the "shared post" technology, as well as a unique narrow side rail, the VA2ST 2.1 needs even less space to fit wider platforms.
