2 Innerdoorless 60s SCHINDLER Lifts with ORIGINAL MOTOR in Biel, Switzerland

Timestamps: 0:00 intro 0:25 normal ride 3:52 motor room 7:18 car top / lift shaft 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.
