CM attachments for material handling
Effective material handling involves much more than moving a load from one point to another. On a construction site, it also means gripping irregular objects, separating recoverable materials, collecting waste, feeding subsequent processing stages and positioning loads with control. To meet different operational requirements, CM Srl offers the G Series sorting grapple.
G Series sorting grapple for gripping, sorting and positioning
The G Series sorting grapple is designed for sorting and handling solid materials. Its continuous 360° hydraulic rotation allows the operator to orient the grapple without repeatedly repositioning the excavator, making it easier to grip large, heavy or irregularly shaped objects.
The high clamping force holds the material securely during lifting and transfer operations, while the geometry of the jaws ensures a precise grip. The range includes models for excavators in different weight classes, from compact machines to excavators used on the most demanding construction sites. Cutting edges that can be replaced directly on site and easily accessible components make the attachment suitable for continuous operation.
The G Series is used for the demolition of lightweight structures, the handling and sorting of aggregates, recycling operations and landscape maintenance. It is also suitable for handling logs, stones, pipes and other irregularly shaped objects. Continuous rotation and high gripping precision provide accurate control of the load during positioning, making the grapple particularly suitable for constructing and restoring embankments by placing boulders and rock.
What materials can be handled?
The choice of attachment primarily depends on the nature of the load. Demolition work may involve concrete blocks, bricks, stones, sections and other metal components, pipes, beams, timber elements and construction materials of different sizes. In these applications, a sorting grapple makes it easier to separate materials, arrange them in designated areas and load them onto vehicles for transport or recovery.
At recycling facilities, material handling is closely linked to sorting. Wood, metals, plastics, bulky waste and mixed waste fractions must be gripped, separated and directed towards the next processing stage. The G Series’ 360° rotation provides a practical advantage when an individual item must be removed from an irregular pile or positioned accurately.
In the agricultural sector and in landscape maintenance, logs, branches, stumps and green waste have irregular shapes and varying volumes. The sorting grapple makes it possible to grip, handle and stockpile these materials with control, simplifying cleaning, loading and work-area organisation.
On construction sites, in quarries and mines, in tunnels and during underground utility work, gripping attachments can handle stones, aggregates, pipes and excavated material. Working directly with the carrier machine reduces the need for manual operations and creates a smoother workflow between excavation, sorting, loading and stockpiling.
How to choose the right material handling attachment
The first parameter to assess is compatibility with the carrier machine. Attachment weight, lifting capacity, hydraulic pressure and flow rate must be compatible with the available excavator, skid steer loader or backhoe loader. Selecting an attachment solely on the basis of load size may result in an inefficient configuration that is unsuitable for the characteristics of the machine.
It is also necessary to consider the shape, consistency and behaviour of the material. For boulders, logs, pipes, bulky scrap and components that must be positioned accurately, a grapple capable of orienting the load is preferable. For loose waste, branches, mixed debris or materials that must be collected and retained, the sorting grapple can be equipped with dedicated closing plates fitted to the jaws. These reduce material loss and make loading and handling easier.
The required level of precision is another decisive factor. The G Series is particularly suitable when the operator must sort, rotate and position individual objects. Correct mounting configuration allows the attachment to be properly integrated with the carrier machine and ensures that its performance can be used to its full potential.
Greater control and productivity in material handling
Mechanising material handling reduces manual operations, improves load control and helps keep the work area organised. Grapple rotation limits the need to reposition the excavator, while the dedicated closing plates that can be fitted to the jaws retain loose materials and waste more effectively during transfer. The result is a smoother workflow, greater precision and more efficient management of the different material fractions present on site.
The choice should therefore not be based on a general handling requirement alone, but on the nature of the material and the operation to be performed: gripping, sorting and positioning solid objects, or collecting and retaining loose materials by fitting specific closing plates to the jaws. By assessing the carrier machine, material, load weight and application context, it is possible to identify the most effective configuration.
Find the CM solution best suited to your needs!
Every application requires a specific configuration: material type, load weight, carrier machine and hydraulic system specifications directly affect performance, safety and productivity. The CM team will help you identify the most suitable solution by checking compatibility, mounting configuration and technical parameters before installation.
