Elevators take up a remarkable amount of space in buildings. This is especially true for high-rise buildings, as the cable system means that only one elevator car can be used per shaft – thus allocating a huge amount of floor space to that single car. Freelevator is a cable-free elevator, allowing multiple cars to operate across one shaft. It operates on Mecanum wheels to gain traction from the shaft walls, and is able to move both vertically and horizontally. The absence of cables also allows the elevator to travel the full length of a building regardless of its height and breadth.
