In roadworks, operational requirements are never theoretical; they arise every day directly on site.
The CBS MK was born in exactly this way, from a concrete need identified by a company that works daily in excavation, earthmoving, and asphalting.
The requirement was clear: to unload the material collected by the sweeping bucket into high-sided trucks—such as four-axle and articulated lorries—while ensuring a full load every time.
When the attachment adapts to the job
To meet this need, MC Costruzioni, a road construction company based in Volpago del Montello, approached CM Srl with a very specific request: to develop a sweeping bucket capable of performing this type of unloading.
This led to a direct collaboration between road operators and equipment manufacturers, resulting in the joint design and construction of the first CBS MK sweeping bucket: a clamshell bucket with an integrated sweeper, capable of unloading efficiently even into high-sided lorries, while consistently achieving full load capacity.
Over time, the CBS MK has evolved to meet different operational requirements.
Today, the brush can be detached, allowing the 4-in-1 bucket to be used on its own. This configuration is particularly useful when handling large volumes of material, such as road millings, where increased load capacity and faster handling are essential.
In this setup, the bucket becomes a truly multifunctional tool: in addition to loading and leveling material, claws can be fitted, further expanding its range of applications—for example, for collecting branches and bulky materials.
Reliability measured in working hours
As reported directly from MC Costruzioni’s on-site experience, one of the most significant aspects of the CBS MK is its durability.
The first unit produced, still in operation today, has exceeded 6,000 working hours and remains in perfect working condition.
This tangible result goes far beyond any technical data sheet and confirms the philosophy behind the development of this equipment: high-quality materials, a structure designed for heavy-duty applications, and solutions built to withstand continuous use in contact with road millings—where strength and reliability truly make the difference.
