Demolition: marks end of era and new beginning - Construction & Construction Materials - Demolition and Remediation
Demolition gives a mental strong image, the act of destroying something is so powerful and it is certainly not for the faint of heart.
But there is another side to it, hidden away, and it is all the planning and organizing behind the scene. It is the stage that pushes for progress, the development begins at the early stages. While demolition is the end of an era, its planning is certainly the new beginning.
Big part of the operational aspect is the disposal processing of the demolition waste.
Operations in suburbs and in large metropolitan cities can have logistics, dust and noise restrictions, that require to be resolved rapidly and economically. Not forgetting, of course, the cost of transporting materials to the dump, an expenditure item which can sometimes be unsustainable for companies.
For le last 17 years MB Crusher’s product range have been operating all over the world, resolving the problems companies have to deal with, in the workplace.
Worksite with the need to reduce noise and dust and manoeuvre easily in narrow spaces: in Germany, for example, the use of the MB crusher bucket has enabled many enterprises to eliminate the costs for transporting materials to the dump and salvage all the aggregates existing on the worksite. While considerably reducing emissions and consumption levels and damping acoustic pollution. In particular, in the region of Hessen, a MB customer had to demolish a house in the centre of a residential area. With just one machine (excavator and crusher bucket BF80.3), the work was rapidly completed and all the waste materials were salvaged and used to refurbish the courtyard.
In Bavaria, on the other hand, the crusher bucket model BF90.3 was used in a city to restore one of its most important squares, in front of a church. The crusher bucket crushed the cobblestones and limestone blocks produced by previous excavations. The aggregates were immediately reused on the same worksite for filling in the foundations of the new square.
When buildings are close together, vibration represent a limitation, MB crusher has got a unit that will solve also this problem. MB drum cutters have the patented direct drive twin motor system, that distribute the force of the two rock cutter heads in different ways. Since the power of the two drums is managed based on the toughness of the material, the vibrations transmitted to the excavator arm are absorbed. In Mexico, as MB-R800 drum cutter mounted on a 20 ton Cat excavator managed to eliminate all the excess material on a wall of a shopping mall.
One other, of many, problems is safety, both in terms of personnel and the moving of vehicles, machinery and material. A practical example of efficiency as regards safety is provided by a worksite in a small Italian city, where a demolition company used the MB Crusher MB-G900 grapples model in order to demolish a three-floor building in a residential area. This was a winning choice thanks to the unique features of the product: it is safe (it is equipped with a fall-stop safety valve), it makes very little noise (thanks to the silent block), it is easy to maintain and versatile (its claws are interchangeable).
Further north, in the United Kingdom, a small company purchased an MB crusher bucket for the specific purpose of recycling the material generated by the demolition of an old school. After they had reduced its volume, they reused it for the construction of a play-park, thereby avoiding having to rent expensive and cumbersome crushing systems. There was already an excavator on-site. All they had to do was to install the crusher bucket and quickly bring the works to completion. Saving time, money and not to mention the impact on the environment, reducing carbon footprint, as well as preserving natural resource.
A totally different matter is reclaiming reinforced concrete. The bars in the concrete makes it difficult to process, making the reclamation stage long and costly. But not with the MB units, in France, for example a combination of a crusher bucket BF80.3 with an iron separator and a New Holland excavator are paring up to recycle the railway sleepers which were cumulated. In Brazil, the accumulated items were long lightposts, discarded as waste due to the difficulty of the reclaiming process. But with the use of a Bucket Crusher BF60.1mounted on a Case CX130B, these old posts became font of income: easily processed to extract the iron which is then resold.
The alternative in the market given by MB jaw crusher bucket, is a cost-effective way where concrete can be separated from the iron. To facilitate this operation the suggestion is to load the bucket with an MB grapple and let the jaw and gravity do the rest. Alternatively, skilled operators can feed the bucket maneuvering the excavator, a magnetic kit installed can also facilitate the separation and salvaging the metal.
All Mb Crusher units can work with any brand of excavator, utilizing their hydraulic system, so material that represented difficult waste to dispose can be not only a revenue font, but an easy task to accomplish.
Therefore companies using MB Crusher Buckets can really have the opportunity to be ahead of schedule and within budget, even in jobs considered challenging or drudgery.
