These lifts are situated in a mixed use building in the city of Biel/Bienne. They were installed upon construction of the tower block which contains offices and apartments.
The lifts are set up as a group of two. The floor layout of the building consists of a basement (French SS = Sous Sol), ground floor (French P = Parterre), intermediary floor (German ZG = Zwischengeschoss) and the upper floors 1 to 14. The motor room is located on floor 14, which is only served by the smaller lift on the left.
The layout of the lifts is very unique: As the highest floor served by the smaller lift is the motor room floor, the motor of said lift is located next to the shaft and the ropes go upwards from the traction sheave and are then diverted over above the shaft via two sheaves for the car and counterweight respectively. The bigger lift on the right is built in a normal top drive configuration as it does not serve the top floor. It also skips the intermediary floor ZG. Due to the motor room being directly above the 13th floor, the big lift has a reduced headroom. The lifts are driven by Schindler W56 winches with two dedicated motors for slow and fast speeds. In order to fit both machines into the motor room, the motors for the big lift were placed on both sides of the winch. The motor for fast speed contains brushes in order to subsequently reduce rotor resistance until shorted upon each start. This helps to reduce the inrush current and is done via the large wire resistors above the winch.
The lifts have been modernised in 1999. The electrical installation has been completely rebuilt with new BP302 controllers and new DMG fixtures. A VFD has not been added, the list still remain with a standard 2-speed drive today. The original motors have been kept, which makes these lifts a true rarity! In 2019 the BP302 controller has been swapped for the newer BP408 with the logic cabinet including all the wiring remaining untouched. This is a big upgrade as the BP408 is a way more reliable controller and it makes these lifts even more unique, as one usually never sees this modern controller with a 2-speed drive configuration.

Wunderschön 🛗👌 super das sie erhalten worden sind 👍

[@TheLiftDragon]

Dankesehr! Ja, sind echt tolle Anlagen.

[@asetatlikalem]

Even with original freaking motor brakes, schindler did a good job

[@TheLiftDragon]

They sure did! Also love that they have new ropes and new traction sheaves. Motors have also been overhauled about 5 years ago.

[@crocoland6330]

This can be described by 3 words. Build to Last.

[@TheLiftDragon]

Absolutely!

[@RODALCO2007]

Nice lifts, I like this set up when you can see the level doors slide past. And good to see level 13 which they skip in the USA. Beautiful motor room, quality equipment and awesome sounds. Great lift surf in the later part of the video. I take it that you work in the lift industry.

[@TheLiftDragon]

I'm glad you like it! We don't skip floors here in Switzerland, it's generally rare in Europe. I've seen it once in person in Germany though. These innerdoorless lifts always fascinated me when I was a kid and I still really like them. They're something you don't find very often in other countries.

[@ElevatorExploration]

Magnificent elevators, it is a very good thing that they have been modernized suchlike.

[@TheLiftDragon]

Indeed. What we see here now in my opinion is the best possible outcome.

[@LadySophieofHougunManor7325]

Fantastic channel n video what is it that causes that nice whine on the lifts is it something on the motors ?

[@Biasca1]

Schönes Video! Die Antriebe gefallen mir!

[@TheLiftDragon]

Dankesehr!

[@joris3842]

Neue Steuerung mit 2-speed, sieht mann nicht oft! Super! Und dabei noch die originalen Maschienen mit Anlaufwiederstanden 😆

[@TheLiftDragon]

Ja, das ist wirklich eine Seltenheit! Gerade eine BP408, das neuste aus dem Hause BP. Ich mag auch die neuen Treibscheiben und neue Seile sind auch drin. Und die Motoren wurden von Elektromotorencenter Thun überholt. Ich denke, die Anlagen werden so noch lange bleiben, denn hier wurde viel investiert.

[@joris3842]

@@TheLiftDragon Dan denke ich auch ja. Zum glück haben Menschen noch ein Hetrz für alte Technik 😄

[@LGCT]

At least these lifts have the original motor, no inner doors and rare DMG buttons. Do these lifts have a chime?

[@TheLiftDragon]

No, these lifts don't have a chime. Most lifts in Switzerland have neither a chime nor a voice.

[@fw6797]

Dit is prachtig zeg , dat ze nog lang mogen draaien zonder storingen.

[@TheLiftDragon]

Indeed.

[@Lifts_in_Austria]

Sehr schöne Anlagen👍, diese Motoren laufen bei guter Pflege ewig. Leider sind Innentürlose Aufzüge in Österreich schon ziemlich selten und in manchen Bundesländern schon unzulässig.

[@muhammadhlv]

It is very interesting, how I see, two electric motors and one of them is a collector, and between them there is also a brake drum, did I understand correctly?

[@TheLiftDragon]

Both motors are 3ph asynchronous AC motors. The one with the brushes is for fast speed has its rotor windings open and they are connected to the large wire resistors ontop the gearbox. When the lift starts, the resistors are bridged by the contacts at the back of the resistors at 5:18. With the resistors between the rotor windings, the inrush current is lower and the motor starts slower. On large freight lifts with that setup there are even more contacts and they close very slowly.

[@muhammadhlv]

@@TheLiftDragon Thanks for the explanation

[@Swissvator]

@Hampi-Vator hat glaube ich die alte Steuerung gefilmt also befor der ersetzr wurde.

[@TheLiftDragon]

Nein, die originale Relaissteuerung flog hier 1999 raus und damals gabs noch kein KZbin. 1999 wurden auch die neuen Tableaus mit den DMG Knöpfen eingebaut. Was 2019 passiert ist, ist folgendes: Die BP302 Steuerung von 1999 wurde durch eine neue BP408 ersetzt. Das merkt aber niemand, der den Schrank nicht aufmacht, da hier wirklich nur das Steuerungsboard getauscht wurde. Von aussen merkt man das überhaupt nicht, auch die Schaltschränke sind geblieben. kzbin.info/www/bejne/ioSsqnukedJ0itk In diesem Video siehst du, wie die alte Steuerung ausgsehen hätte.
