MB-C50 Crusher Bucket At Work

Where is the crusher now? Do not disturb

The MB-C50 crusher bucket at work in the Bavarian residential area.

At 45 Franziskaner Strasse in Munich, during the war, people fled to shelter in neighbouring buildings, escaping via underground tunnels to avoid being stopped in the streets. Some of these tunnels were built as early as 1700.

Today, the galleries and tunnels are still there, underneath modern buildings, houses and shops that often now need to expand in order to accommodate new tenants or new businesses. Already crowded city centers cannot spread outside; there are streets, parking bays, sidewalks and generally little space. So the courtyard is the only available choice.

This happened at number 45, where the German company Stöger Baggebetrieb took on this civil renovation and began to build an extension by demolishing part of the inner courtyard moving on to build new foundations.

The biggest challenge was to safely manage the construction site in a short time and without disturbing the neighbourhood. The difficulties faced were: move the equipment, obviously compact, through the narrow courtyard entrance, do not make too much dust or too much noise or vibrations, manage the excavated material, work fast and contain costs. Practically, maximum efficiency, no squandering.


Logistic Management And Site Safety

At number 45 the courtyard entrance is narrow and the inner yard itself is small.

The only equipment capable of fitting without problems is a 5-tonne mini-excavator. Others could not have carried out excavations operations.

And then? What to do with the excavated material?

At first glance the solution seemed to be to load it onto small lorries and haul it to the recycling centres to then bring back the stabilised material into the yard to fill the foundation base – a logistic management nightmare with too many lorries to coordinate in and out, timing issues, unforeseen costs, downtime and city centres truck circulations limitation. All factors that could have made this job never-ending and very expensive.

The cost-effective solution?

Install a crusher bucket MB-C50 on the Cat excavator and do the work directly inside the yard in total safety because the crusher bucket is operated directly from the excavator cab. Manoeuvred in small spaces because the MB crusher bucket collects the material and reduces it on the same spot; the digger does not move, it simply scoops and crushes, which means zero transport costs and hassle-free operations. No lorries passage needed. Among other things, the needed output size can be adjusted by the operator directly at the site in a few minutes without calling in a specialised workshop.

The MB-C50 crusher bucket does not even have haulage costs because it arrives on site installed on the digger that will do the job.

It fits through the narrow doorway – it is small, compact and ready to buckle down. DO NOT DISTURB The Tenants And Respect The Environment

Who would want to have a building site beneath a window? Nobody. Noise and dust bother workers and are harmful to the environment, and vibrations could compromise the building structure. However, the MB-C50 crusher bucket is equipped with a dust nebuliser, which reduces noise compared to traditional crushing with only a few vibrations to the arm and zero to buildings. Less machines moving means less pollution and even noise. Reusing the extracted material on site results in less costs and less pollution. And this is how, at number 45, demolition waste becomes a productive resource for the site itself: to fill the new building foundations.

When the opportunity to reuse does not arise at the same site it becomes a commercial resource – it can be sold to other companies or used for other construction sites for trenching, as road-base, or even as a decorative element.
