When it comes to drum cutters, their strengths and weaknesses would seem obvious. However, there are constant innovations for thistype machinery, which are essential in sectors dealing with digging, cutting, profiling, or reducing hard materials with “millimetric” precision equipment. They are designed to operate in city centres, often on historic buildings, on bridges and performing excavation and demolition work where the hydraulic breaker can create excessive vibrations.

“Precision and timing are the two key factors in our line of work, and few people realise the accuracy that is asked of us, and stringent constraints on space, regulations and machinery, to which we must submit,” according to industry experts.

Think of demolition of buildings in high-population areas that require carving of foundation and concrete pillars, to get an idea of delicate situations in which a precision drum cutter machine is required to operate. Or, the lowering and levelling of roads and bridges, where surfaces being treated are asphalt and concrete, or profiling work in confined spaces for the creation of city ducts. In agricultural sector, precision drum cutters are also indispensable for clearing and dredging land, creating irrigation systems, levelling river beds, etc.

With its 20-year experience in building innovative Crusher Buckets and Screening Buckets, MB Crusher has created a new concept of hydraulic drum cutter.

Production Manager Diego Azzolinsays, “In addition to existing patents on MB equipment, we’ve recently dedicated ourselves to drum cutter machinery, designing a highly evolved and innovative new product – the line of MB Crusher drum cutters, which is the only one in world market to utilise a Direct Drive Twin Motor System. This direct transmission dual motor system is protected by our unique patent, allowing for a differentiated distribution of force on the two drums. This provides an enormous advantage, since power force is managed autonomously by the drum cutter according to the material’stoughness and resistance.”

Moreover, customers can opt for a variety of drum and tooth kits according to the type of material being processed. This new generation of standard drum cutters also adopts an integrated Power Boost to augment the power of the cutter head, which requires more force and obtains exceptional results.

“Among the major issues, we encounter on work sites are torsions and vibrations on the operating machine arm, with consequent enormous costs due to wear. Not to mention noise and dust restrictions that protect city centres and highly populated areas,” say industry operators.

MB Crusher deals with this challenge via its automated control results in a No Torsion System: structural stress on the excavator’s arm is absorbed and drastically reduced, to increase precision and durability while benefiting cost savings and maintenance times.

Specifically for construction sites in urban centres, we’ve also designed the dust suppression kit and drum cover kit, to reduce dust emissions and allow work to be carried out in closed environments and areas with high vibration restrictions.

“Yet another extraordinary innovation,” continues Azzolin, “was introduced to help construction site managers deal with delivery time constraints: our drum cutter heads are designed to be easily replaced on site, in less than an hour. Unthinkable until now. Indeed, this procedure required extended downtime to take the cutter to an authorized workshop. Being able to change the drum in just under an hour gives the construction site a strong competitive advantage”.

To protect the machine’s central casing, specially designed wear plates have been applied, as well as a protective high-temperature reduction kit designed to lower the operated machinery’s oil temperature without altering its performance.

“Handy and easy to use,” summarizes Azzolin, “the all-new MB Crusher hydraulic cutters make work at construction sites more profitable, where precision cutting, maintaining depth, reducing waste and compliance with regulations are daily priorities. Like gigantic “scalpels” that provide precision manoeuvring where every centimetre has a productive value and cost.

The cutter rotation kit is designed specifically for road work and trench digging, allowing the machine operator to rotate the cutter directly from the cab without stopping the excavation work: an extremely beneficial operation in terms of time and effectiveness. The cutting depth adjustment kit allows operators to set the trench depth, to remove only the necessary amount of material providing a significant reduction in waste disposal costs.

Thanks to their high degree of precision, power and adaptability, the new MB hydraulic cutters for excavators, loaders, and backhoe loaders are the most innovative and determined response to excavation, demolition and profiling work, especially in urban sites, virtually eliminating the constraints and costs of downtime, waste management, maintenance and wear.
