Components
Vacuum elevators are easier to install, maintain and operate than traditional elevators. They are especially ideal for existing homes and luxury boats due to their compact design and the fact they DO NOT REQUIRE the excavation of a pit for the elevator or the installation of shafts.
Air pressure above and beneath the elevator cab are the key to their transportation.
Vacuum elevators consist of three main parts
1. The outside cylinder - a self-supporting aluminium circular frame with curved polycarbonate infill walls. 2. The internal cylinder - the elevator car runs inside the self-supporting outside cylinder. The walls of the car are made of polycarbonate, the roof houses a silicone base seal which ensures a smooth operation and guarantees normal atmospheric conditions for the passengers. The locking system is activated on reaching the required floor and provides a precise, smooth stop for the car. 3. The upper control compartment (the head unit) - this houses the turbines, the vacuum pump, valves and controls for the vacuum elevator. The head unit comes in a standard model which is positioned at the top of the elevator's outside cylinder or in a split-remote model which can be located up to 10 meters from the elevator. ♦ A split-remote head unit is usually required when there is insufficient head room on the last floor of the elevator or the ceiling void above the elevator is inaccessible. |
