The ultimate lifting device
Published 27/6, 2014In the German town of Bochum about 3,600m2 of the Town Hall needed remodelling and 12 inner courtyards required concrete sawing to make way for new offices.
The remodelling was undertaken in three floors that also required crossbeams to be sawn and disposed of. A total of 4,000t of concrete had to be sawn into 1.5t blocks and removed. This rebuilding was especially difficult due to the central location of the Town Hall, as cranes could not be used for lifting out the concrete blocks.
The access problem was solved by using Feltes lightweight aluminium gantry cranes, made at Ratingen about 40km from Bochum. Several types of gantry cranes were put into operation. The standard type with a height of 3m and maxi with a height of 4m, as well as the under load movable types were used. With these cranes the concrete blocks were secured, lowered and removed. The light aluminium gantry cranes were a great help as the concert blocks were lifted and transported through the existing buildings to the container disposal.
