Montageeber, Observation tower and crane in Eberswalde, Germany.

Montageeber is a steel lattice crane standing about 190 feet (58 m) tall in Eberswalde, Germany, built from welded steel profiles. It sits on the former grounds of the Kranbau Eberswalde factory and is now protected as an industrial monument.

Built in 1954 as the first of a series of assembly cranes, the Montageeber was used at Kranbau Eberswalde until 1990 to assemble and disassemble port cranes. It was dismantled in 2001, rebuilt at the edge of the factory grounds, and only then placed under monument protection as an industrial monument.

This structure shows how local craftspeople and engineers developed and used advanced crane technology in Eberswalde. You can see the technical solutions that workers employed during assembly and operation.

The viewing platform sits 28 metres up and is reached by a staircase, not a lift. In good weather the Berlin TV Tower, some 50 km away, can be made out from the top. The crane stands at the edge of the Familiengarten Eberswalde grounds, which also hold other surviving parts of the former factory.

The crane uses a rocker mechanism with moving counterweights that allowed heavy loads to be moved while consuming far less power than comparable machines. This made it more efficient to run on a daily basis than other cranes of its time.
