The pitless elevator can be installed directly on the surface of the ground without any civil construction pits. It is a very convenient and space-saving elevator, suitable for installation in domestic environments and high-rise duplex buildings with limited space.
In the current elevator structure on the market, hydraulic elevators and traction elevators need to reserve pits, and screw elevators can be used as pitless elevators. Therefore, there is no need to reserve the big pit of the traditional elevator when installing the elevator.
The screw elevator is driven by a nut and screw type, and the unique nut and screw engagement structure can greatly reduce the probability of falling and rising from the top.

The height of the bottom space is only 37mm reserved for the elevator in the villa.
