How Does the Schmid Peoplemover Work?


In 1999 Emil Schmid, the owner of Schmid Maschinebrau in Sonnenbuehl near Stuttgart invented a new form of vertical transportation. He applied for a patent in the same year and when it was granted he named his invention the Schmid Peoplemover. He built the first prototype at his engineering factory and then worked with Thyssen Aufzugswerke (now part of ThyssenKrupp) to scale production of his Peoplemover system. The first Peoplemover was installed in Pfulligen, Germany in December 2001.   

What is the Schmid Peoplemover?

The Schmid Peoplemover enables pedestrians to cross major roads and thoroughfares or railways without the need for traffic lights or railway crossings. This is achieved by taking passengers up and over the traffic. The Peoplemover is built as a free hanging system and consists of two towers, a bridge connecting them and a lift car. The Peoplemover is ideal for pedestrians in wheelchairs or with strollers or suitcases. It is of benefit to all pedestrians and cuts overall journey times because there is no need to wait for traffic lights or railway crossings.

How Does it Work?

First of all passengers enter a lift car and are transported vertically to bridge height and then horizontally across the bridge before being transported vertically down on the other side. When travelling vertically, the lift carriage and car are held in the lifting gear guides before gliding smoothly over into the horizontal travel position with the aid of a special guide rail and a sophisticated mechanical system. Construction of the Peoplemover is completed within 3 days and does not require as much surface area as a traditional underpass. The lift car is made of aluminium with stainless steel centre closing doors and a window. It

has a rated load of 600kg and a speed of 1mps vertically and 2mps horizontally. There is a limit of 5 metres for travel height and a span of 20 metres. A total of 720 passengers per hour can make the crossing in both directions.

How Many Schmid Peoplemovers are in Existence?

Peoplemovers can be installed in a wide variety of scenarios: the crossing of streets, railways and waterways etc, linking motorway service stations to car parks and at shopping centres, exhibition centres, leisure parks, hotel complexes, and hospitals. There are currently 3 lifts of this type in Germany at Pfullingen, Altenbach and in Berlin. You can watch a video of the one at Altbach Peoplemover here.

Peoplemovers are a very special type of vertical transportation. Dunbar and Boardman is the lift, escalator and access equipment consultancy. Are you currently planning a project that will involve vertical transportation? We would be happy to discuss with you.

Double Deck Elevators: Where was the first one?

 Double deck lift within the Eiffel Tower

A Double-deck elevator is a type of elevator where two cabins are attached to each other. One In a typical example, one of the elevators cabins will stop at even floors and the other elevator cabin can stop at the odd floors. They are also useful for  for delivering high volumes of people to a Sky Lobby in super high rise buildings. Double-deck elevators save time and space in high-occupancy buildings by mounting one car upon anotherhaving two cars in the same vertical shaft. The efficiency of Double-deck elevators serving all floors, can be further enhanced by the use of a destination control system.

The first Double–deck elevator was installed in The Eiffel Tower in Paris in 1889. by The Otis Elevator Company.  Charles and Norton were carrying on the work of their father, Elisha.  The Eiffel Tower has double-deck elevators built into the legs of the tower, serving the ground level to the first and second levels. Even though the shaft runs diagonally upwards with the contour of the tower, both the upper and lower cars remain horizontally level. The offset distance of the two cars changes throughout the journey.

There are four elevator cars of the traditional design that run from the second level to the third level. The cars are connected to their opposite pairs (opposite in the elevator landing/hall) and use each other as the counterweight. As one car ascends from level 2, the other descends from level 3. The operations of these elevators are synchronized by a light signal in the car.
 

Where are other examples of Double–deck elevators?
