The Scharnebeck ship lift (near Lüneburg) belongs to the northern of the two canal stages of the Elbe Lateral Canal federal waterway , for which the Uelzen Waterways and Shipping Office is responsible. The Elbe Lateral Canal connects the Elbe near Artlenburg with the Mittelland Canal near Edesbüttel west of Wolfsburg . The lift was built in 1974 as the world's largest at the foot of the Geestrand on the Elbmarsch in Scharnebeck , northeast of Lüneburg and nine kilometers south of the Elbe. The first ship passed the ship lift when the canal between the Elbe and the port of Lüneburg was partially opened on December 5, 1975.

It is easy to visit thanks to several promenades and, in connection with the nearby museum, is a popular destination. Around 500,000 visitors visit the elevator every year.

Technical specifications

  • Design: double vertical lift with counterweights and 2 independently working troughs in 4 guide towers each
  • Construction costs: 190 million DM (after retrofitting)
  • Fall height: maximum 38 m (depending on the water level of the Elbe)
  • Trough dimensions: usable length / usable width / jamb depth 100 m / 11.8 m / 3.38 m (actual length between the gates = 105.6 m)
  • Trough gates and maintenance gates in the head and the lower head are lift gates
  • Gate protection devices: The safety ropes attached to the trough gates to protect against ship impacts reduce the usable length for shipping to 100 m
  • Total weight of the trough filled with water: 5,800 t
  • Total weight of the moving parts of a trough (including water): approx. 11,800 t
  • Weight of a counterweight disc made of heavy concrete (224 pieces per trough): approx.26.5 t (total counterweight 5,936 t per trough)
  • Dimensions of a counterweight disc: 6.8 m × 3.4 m × 0.32 m
  • Thickness of the 240 steel cables per trough: 54 mm
  • Drive of a trough: four electric motors with 160 kW each
  • Duration of a lifting / lowering process: 3 minutes
  • Duration of a passage (including entry and exit): 15–20 minutes
  • Output of the pumping station for the water supply of the canal from the Elbe: 6.75 m³ / s

  • The canal bridges over Adendorfer Straße as a connection between the upper outer harbor and the troughs

  • The boat lift seen from the headwater

  • 38 m is the maximum difference between the upper and lower water (height of fall)

  • View from the upper water into the western trough

  • West view with both full length troughs

  • GMS Dorle from Lüneburg in the sinking trough

  • GMS Niedersachsen 04003680 heading towards the Elbe

  • The threaded spindle of the adjustment device and ropes of the counterweights

  • Ship lift under construction September 1971 - View to the east, retaining wall to the headwater

  • Ship lift under construction September 1971 - southern towers in front of the retaining wall towards the upper water - concreting work with climbing formwork

  • Ship lift under construction September 1971 - Connection to the underwater with a view of the inlet structure to the pump house

  • Ship lift under construction January 1973 - trough

Surname

Although the official name is Schiffshebewerk Lüneburg, it is locally called Schiffshebewerk Scharnebeck because of its proximity to the community of Scharnebeck.

Planning for a lock

The limited usable length (only ships up to 100 m in length) as well as the necessity to divide push convoys have prompted plans for the construction of a new lock with a large length. This should have a usable length of 225 m with a lifting height of 38 m. This new building is included in the Federal Transport Infrastructure Plan 2030 as an "urgent need".
