4×1 bucket: what it is and what it is used for
The 4×1 bucket is a multifunctional attachment that allows several operations to be carried out with a single accessory: it can be used as a standard bucket to load material, opened as a blade to push or level, closed or partially opened as a grapple to grip, or opened to discharge in a more controlled way and distribute the material more effectively.
Thanks to its opening and closing system, the 4×1 bucket therefore makes it possible to collect, retain, handle and discharge different types of material, such as debris, pieces of asphalt, waste material, road residues and coarse materials.
How does a 4-in-1 bucket work?
The 4-in-1 bucket works thanks to an openable structure that allows the same attachment to be used in different configurations. When closed, it works like a traditional bucket to collect, load and transport material. When opened, it can be used to push, level, grip coarse materials or discharge the content in a more controlled way. The opening and closing system allows the material to be retained more effectively during handling and the discharge to be managed with greater precision, especially when the material has to be transferred into trucks, containers, semi-trailers or vehicles with high sides.
Applications of the 4×1 bucket in road maintenance
The applications of a 4×1 bucket are particularly useful in road maintenance operations. Thanks to the possibility of working in different configurations, this attachment makes it possible to collect, load, push, level and discharge different types of material with a single accessory.
In roadworks, 4-in-1 buckets can be used to collect pieces of asphalt, debris, milling residues, waste material, gravel, soil and other coarse materials found on roads, shoulders, yards, industrial areas and work zones. The openable structure allows the material to be retained more effectively during handling and discharged in a more controlled way into containers, trucks or dedicated collection units.
CBS MK: the multifunctional solution by CM Srl
The CBS MK by CM Srl is a sweeping bucket for road maintenance that, instead of the classic collection bucket, integrates a 4×1 bucket. This configuration combines road surface cleaning with material collection, containment and controlled discharge, increasing the versatility of the attachment during operations on asphalt, carriageways and yards.
During road maintenance, asphalt repair or cleaning of operational areas, the material to be managed can vary both in type and size. The carriageway may contain dust, milled material, gravel, fine residues, but also pieces of asphalt, more substantial debris and coarse material. The CBS MK makes it possible to handle both needs: on one hand, it cleans the surface with the brush unit; on the other, it uses the 4×1 bucket to collect, contain and discharge the material into containers, trucks or dedicated collection units.
The advantages of using the CBS MK
Cleaning function
In sweeper mode, the CBS MK allows the road surface to be cleaned and the material to be collected directly inside the 4-in-1 bucket. This function is particularly useful after cold planing work, asphalt maintenance, road repairs or operations where fine residues, dust, gravel and material accumulated on the carriageway need to be removed. The brush unit conveys the material into the bucket, keeping the work area cleaner and reducing operating steps.
Use of the 4×1 bucket only
In the CBS MK, the brush body can be detached from the 4×1 bucket. This allows the operator to use only the bucket when larger materials, broken pieces of asphalt, coarse debris or large quantities of material need to be collected without requiring the action of the brush.
This possibility makes it possible to adapt the attachment to the type of operation, switching from the sweeping configuration to the 4×1 bucket configuration according to the size and quantity of the material to be collected.
Discharging material onto high-sided trucks, 4-axle vehicles and semi-trailers
Another important advantage concerns the discharge of the material collected during sweeping. Thanks to the openable 4×1 bucket, the material conveyed inside the bucket can be discharged in a more controlled way into trucks, containers, semi-trailers, 4-axle vehicles or vehicles with high sides.
During discharge, the opening of the 4×1 bucket facilitates the outflow of the material and allows the operator to better manage the flow and discharge point. This makes the CBS MK particularly suitable for roadworks, where the collected material often has to be transferred directly onto transport vehicles.
The CBS MK is therefore a machine designed for the road sector, where cleaning, collection and material management must work together. The presence of the 4×1 bucket expands the possibilities of use of the sweeping bucket, making it suitable not only for surface cleaning, but also for managing milling residues, pieces of asphalt and larger debris.
For those looking for a machine capable of offering productivity, flexibility and quick transformation, the CBS MK represents a complete technical choice. It is an effective answer for companies that want to optimise work on site with a robust, versatile attachment suitable for multiple applications.
