The MB-C50 crusher bucket is at work in the Bavarian residential area quietly, efficiently and effectively
At 45 Franziskaner Strassein in Munich, Germany, during the Second World 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, shops, that more often now, need to expand in order to accommodate new tenants or new businesses.
Already crowded city centres 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 StögerBaggebetrieb, took on civil renovations and began to build an extension by demolishing part of the inner courtyard moving onto build new foundations.
The biggest challenge was to safely manage the construction site, in a short time and without disturbing the neighbourhood. The difficulties to face were several: move the equipment, obviously compact, through the narrow courtyard entrance. Do not make too much dust or too much noise, nor vibrations. Manage the excavated material: Work fast and contain costs. Practically, maximum efficiency, no squandering. How?
Logistics and site safety
At number 45 the courtyard entrance is narrow. The inner yard itself is small. The only equipment capable of fitting in without problems is a 5 ton mini-excavator. Others could not have carried out excavations operations.
So, how was the job done?
What would one do with the excavate material? At first glance the solution seemed to be to load it onto small lorries and haul it the recycling centres, and then bring back the stabilized material into the yard to fill the foundation base.
A logistic management nightmare. Too many lorries to coordinate in and out. Timing issues. Unforeseen costs. Downtime and city centres truck circulation rules to be negotiated. All these factors could have made this job never-ending and 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. Manoeuvrable in small spaces, the MB crusher bucket collects the material and reduces it at the same spot, the digger does not move, it simply scoops and crushes. Zero transport costs and hassle free operations. No lorry passage permissions needed. Among other things, the needed output size can be adjusted by the operator directly at the site in few minutes, without involving a specialized workshop.
The MB-C50 crusher bucket does not even have haulage costs, as it arrives on site installed on the digger, which will do the job. It goes through a narrow doorway as it is small, compact and ready to buckle down.
No disturbing the tenants
Who would want to have at building site beneath a window? Nobody. Noise and dust bother as well as being harmful to the environment. And vibrations could compromise the building structure.
But the MB-C50 crusher bucket is equipped with a dust nebulizer, which reduces noise compared to traditional crushing means with a few vibrations to the arm and zero to buildings.
Lesser machine movement translates into less pollution and lesser noise. Reusing the extracted material on site means lower costs. 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 be used for other constructions sites, for trenching, as road-base, or even as a decorative element.
For big jobs to be done safely, silently and efficiently in crowded urban sites, the MB-C50 crusher bucket is what you need!
