COLD PLANERS

What cold planers are and what they are used for

Cold planers, also known in technical jargon as road scarifiers or road planers, are attachments designed to perform cold planing, namely the controlled removal of surface layers of materials such as asphalt, concrete or rock, through a milling drum equipped with tools. The work is carried out according to the drum width and the set milling depth, allowing the material to be removed regularly and in a controlled way. For this reason, cold planers are used in road maintenance works, pavement restoration, work on yards, industrial areas and compact surfaces. Cold planers are now essential on modern construction sites because they improve operating efficiency, reduce intervention times and achieve a uniform finish. For this reason, they are used both in road maintenance works and in construction and infrastructure applications.

Types of cold planers

Cold planers differ according to working width, milling depth, the type of surface to be treated and the operating machine on which they are installed. The choice of cold planer depends not only on the type of work to be carried out, but also on the characteristics of the carrier machine.

It is essential to check that the skid steer loader, excavator, wheel loader or backhoe loader has the necessary hydraulic requirements, in terms of flow rate and pressure, to ensure correct operation of the attachment. Only with the right combination of cold planer and operating machine is it possible to obtain effective, constant and safe milling.

• Cold planers for excavators: cold planers for excavators are suitable for localized interventions, linear excavations, trenches for underground utilities and work on surfaces that are difficult to reach with other machines. The excavator arm allows the cold planer to be positioned precisely and to work not only on flat surfaces, but also on vertical walls, inclined or oblique surfaces, such as those found in tunnels, embankments and complex excavation areas, provided that the machine has a hydraulic system compatible with the requirements of the attachment.
• Cold planers for skid steer loaders: they are used for milling asphalt, concrete and compact surfaces, especially in road maintenance works, restorations, urban interventions, yards and industrial areas. The drum width determines the strip of material removed with each pass, while the correct depth adjustment allows the work to be adapted to the type of intervention. In this case too, the choice must take into account the power and hydraulic characteristics of the skid steer loader.
• Cold planers for wheel loaders and backhoe loaders: When the machine available on site is a backhoe loader or a wheel loader, the application of a compatible cold planer can be evaluated. In this case, the choice of attachment must start from the required working width and from checking the requirements of the carrier machine, especially in terms of hydraulic flow rate and pressure. It is therefore not the type of machine alone that determines milling performance, but the correct combination of machine, hydraulic system, attachment weight and type of work to be carried out.

CM cold planer models

CM Srl offers cold planers designed to meet the different operating needs of the construction site, providing specific solutions for excavators, skid steer loaders and other operating machines.

• FS series cold planer – ideal for applications on skid steer loaders and compact machines, perfect for urban works and road maintenance interventions
• FSE series cold planer for excavator – designed for excavators, it allows precise work on horizontal, vertical, inclined or oblique surfaces, making it suitable for localized interventions, tunnels, embankments, walls and areas that are difficult to reach with other machines

Both solutions guarantee high performance in cold planing, combining strength, precision and ease of use. The choice between the different models mainly depends on the type of operating machine and the required milling plane.

How to choose a cold planer

Choosing the right cold planer directly affects work quality, execution times and the overall productivity of the construction site. To identify the most suitable solution, it is not enough to consider a single feature, but it is necessary to evaluate the entire set of operating requirements, from the type of intervention to the machine on which the attachment will be installed.

One of the most important aspects concerns working depth and width. A cold planer must guarantee uniformity, precision and continuity of milling, adapting to the type of intervention required, whether it is surface maintenance or deeper and more structured work. At the same time, it is essential to verify compatibility with the carrier machine: excavators, skid steer loaders and wheel loaders require different configurations, and the correct combination of attachment and operating machine is essential to achieve high performance safely.

Another decisive criterion is the material to be processed. Asphalt, concrete and particularly compact surfaces have different characteristics and require a road scarifier suited in terms of power, structure and tools.

Maintenance and durability of cold planers

To maintain high performance over time, cold planer maintenance plays an essential role. Periodic checks, inspection of the tool condition and correct operating management make it possible to reduce machine downtime and preserve the efficiency of the attachment even in heavy-duty working conditions.

The durability of a road planer depends not only on construction quality, but also on how easily it is possible to intervene on components subject to wear. An attachment designed with maintenance in mind makes routine operations faster, improves work continuity on site and contains overall operating costs. For this reason, when choosing cold planers, it is important to consider not only immediate performance, but also ease of management in the long term.

Difference between cold planers and other asphalt attachments

Unlike traditional demolition attachments, road planers are designed to carry out precise and controlled work. A cold planer does not act by indiscriminately destroying the material, but removes it selectively, allowing intervention only on the affected portion and keeping the underlying structure intact when necessary. This approach makes cold planing particularly advantageous in all contexts where accuracy, result regularity and waste reduction are required. Compared to other asphalt solutions, a road scarifier therefore makes it possible to obtain a more homogeneous finish, better surface preparation and greater control over the intervention, with concrete benefits from both a technical and economic point of view.
