Design Details / Segmented Construction

Due to the adverse conditions at the final installation site, the elevator system (as well as the entire station) was manufactured using a segmental construction method. The most complex segment is the drive station together with the top landing (see image on the right). These were fully preassembled at the factory and transported by flatbed truck to the test installation site in Bremerhaven.

Drive Unit

Due to the limited space, the adverse weather conditions, and the simplicity of the system, a rope drum with two ropes was chosen as the drive mechanism. The drive is powered by a bevel gear motor with a frequency converter.

Stairwell scaffolding

The elevator shaft frame is manufactured in segments and is fully hot-dip galvanized to facilitate assembly at the installation site. The image on the left shows the individual landing platforms with their sturdy revolving elevator doors. For ease of use, these doors are equipped with a stationary panel and a moving panel.

The Control System

Due to the limited supply of spare parts within the station, a standard Siemens S7-300 controller was installed. The control cabinet is located in the heated area of the facility. A connection to the control room is included.
