Cabinlift video is available on-line

Note: Cabinlift service has been terminated (November, 2010) as the functions of the two hospitals has changed and it is no longer needed.

The Cabinlift is made up of field-proven Cabintaxi components. Its functionality can be described as a "connector" technology - linking groups of buildings with each other on a horizontal plane. The experience gained during the testing of the Cabintaxi urban transport system has been used in the creation of an economically attractive alternative to previous transport and handling techniques. The Cabinlift's linear motor drive units and rubber-tired wheels guarantee smooth and quiet travel. A clean form of energy: no problems with exhaust fumes, odors or noise. It has constant travel characteristics in all types of weather, operates without a driver (by automatic or semi-automatic control), is guided by a track, can negotiate gradients and is pollution-free. Being designed to carry passengers, it incorporates extensive safety features. Its high operational reliability is retained by means of regular maintenance, and by check-out procedures for certain components.

Operation and Technical Aspects

Cabinlift is similar to an elevator in its method of functioning. The vehicle is called by pressing a button. An optical indicator shows the direction of travel. The starting button releases the travel blocking mechanism and set the cab in motion. The installation can be guarded against unauthorized operation through key control.

After starting, the cab automatically accelerates to the programmed speed. Before it reaches its destination, the vehicle automatically decelerates to approach speed until it come to a halt at the station.

A built-in speed measuring system, external monitoring of braking paths, two independent braking systems, automatic wheel braking in the event of power failure, battery-powered operation with a special drive vehicle on a separate track: these are all parts of the broad range of safety features.

The ventilated and heated cab, of aluminum light-weight design, has spring-loaded, cushioned suspension. Each bogie is equipped with rubber-tired trailing and guiding wheels. The track grider, in the form of a box section bridge, is resistant to torsional and bending stress. The busbars and the secondary conductor for the drive units and brakes are installed along the track grider. In addition, other supply lines unrelated to the Cabinlift installation (main power, emergency power, heating, communications) can be accommodated along the girder. The track girders are mounted on supports of reinforced concrete, as a rule. The stations in or adjacent to building, as well as the vehicles (3 possible sizes) themselves, would be designed to comply with local regulations. Illustrations of operating components and routing (network design) possibilities are also provided. Several pictures of Cabinlift in operation are also available. Graphics from a proposal to serve the Bremen Central Hospital complex in Bremen, Germany with a Cabinlift system show its excellent application potential.

These pictures provided were taken at an installation at the Schwalmstadt-Ziegenhain hospital in Germany. The attributes of this installation are: 578 meters of guideway, 2 stations, 2 minute travel time between stations, 12-person carrying capacity, 6 meters/second travel speed, fully automatic operation, driven by 2 electric asynchronous linear motors that are unaffected by weather conditions, automatic positioning of vehicle and additional braking system at both stations. It was built in 1975 over a 12 month period and has been operating successful since then. Messerschmitt-Bölkow-Blohm GmbH was the vendor and contractor.

More information on this technology (as well as Cabintaxi) can be obtained from Marsden Burger at the Cabintaxi Corporation, in Detroit, MI.
