| The Essential Parts of the Vacuum Elevator:
Halsten Self-supporting tube built out of specially designed sections. The walls of this tube are made of curved sheets of polycarbonate. The tube is made by modular lengths that fit together easily. The doors are made of the same material. They are airtight and provided with safety magnetic locks. The roof of the tube, made of steel, ensures air tight core and has suction valves and air inlets. elevators ![]() The Halsten Elevator Car - Made of transparent polycarbonate and is mounted on a steel frame. On the cab roof, there is an air tight joint that ensures normal pressure and air conditions for the passenger. elevators An anchoring system activates when reaching the desired floor, thereby assuring the passenger an exact stop with the cab locked at that level mechanically. The Suction Assembly - Can be built and placed in different ways, either on the same tube that holds the cab or separately at distances up to 30ft. from cylinder. In all cases, the motor is monophase. Safety Controls: The upper chamber has a pressure switch which will detect instant repressurization elevators of the upper chamber. If this unlikely incident were to occur, the elevator will brake within 2 inches on free fall. If a sudden power outage occurs while the vacuum elevator is being used, the elevator cab automatically descends to ground floor at slower than normal speed because there is no elevators air being induced into the upper chamber (as is the case when power is on). ![]() Each vacuum elevator comes with an alarm system., elevators emergency ventilation, and door safety switches. The doors can not be opened while the vacuum elevator is in operation. Each cab comes with telephone base mount elevators and wiring for the cab to the vacuum elevator controller located in the pump box above the cylinder. |

| Operation: When the piston gear depressurizes the area inside the lifts cylinder above the vacuum elevator cab, the cab is then lifted by higher atmospheric pressure below the cab. The inside of the vacuum elevator cab always remains at the atmospheric pressure. As air pressure is lowered above the cab, the cab is lifted. elevators ![]() A valve regulating inflow of air in the upper part of the shaft controls the pneumatic depression and enables descent. When the valve lets in air (at atmospheric pressure) into the low pressure chamber, the vacuum elevator cab will safely lower to the desired level. This valve also controls the speed elevators of the cab. The lower part of the shaft is open to ensure free entrance of air at atmospheric pressure. The air suction process simply consists of a suction device that sets the difference in pressures between the atmospheric and that inside the shaft limited by the piston, the side walls and the upper elevators end. ![]() The vacuum elevator cab has locking devices included in the interior of the shaft to stop the cab at the upper and lower limits of travel. ![]() For better safety conditions, a braking elevators system located on the roof of the car activates in case the tube above the vacuum elevator cab has a sudden return to atmospheric pressure. The braking system is made up of either a diaphragm or piston. ![]() |
