How the MB Crusher drum cutter range provides the solution to the challenges faced by certain construction sites
Construction projects on bridges and major roads often have a big impact on people travelling in and out of the city and motorists who are faced with road closures and an increase in traffic congestion. While the work is carried out, city centres and major roads suffer from congestion.
The companies carrying out road works, road maintenance, excavation, renovation and trenching operations are well aware of the challenges as well as the operational and logistical problems they are faced with. Not to mention the added pressure to complete the work quickly and reopen the roads, these requirements substantially increase costs.How to manage excavation and demolition projects, on bridges, tunnels, and major roads effectively, efficiently, and smoothly.
Renovation work was required at the historic Augustusbrücke bridge over the Elbe river in Dresden, for the removal of the
concrete which filled the arches and had caused structural damage. The customer was seeking a solution that would be suitable for the machine already in use at the site - a Liebherr 918 excavator - and that would not cause any damage to the 18th-century structure. MB Crusher provided the solution by recommending the use of an MB-R800 drum cutter (suitable for excavators between 10 and 22 tons). Firstly, the MB drum cutter was used on the diagonal cement lines on the bridge to free up the expansion joints. This was the most challenging phase. However, the MB drum cutter was used without causing too many vibrations or any damage to the structure. Following this phase, the MB-R800 drum cutter was used to remove some of the concrete that filled the arches of the bridge, grinding as far as 3 metres deep.
