The XCMG XM2005K road miller and the Cummins X15

The XM2005K by XCMG is a large-scale cold planer. A machine designed for milling and removing asphalt pavement layers over extensive surfaces, with a broad-ranging target:

• Highways and high-traffic extra-urban roads where it is necessary to quickly remove deteriorated layers across wide lanes;
• Urban roads and city arteries where the ability to work with precision and controlled material discharge minimizes traffic disruption times;
• Airports, aprons, and logistics areas where the flatness of the milled surface and the consistency of the cutting depth are fundamental requirements;
• Parking lots and storage areas with pavement to be renewed or redeveloped.

In all these applications, the XM2005K positions itself as an alternative machine to the “usual suspects” thanks to its core features and specific solutions. Solutions that aim, first and foremost, to simplify maintenance, increase reliability, and stand out in an original way without sacrificing the basic characteristics that industry professionals obviously expect.

The X15 is the Heart of This XGMC Machine

The powertrain heart of the XM2005K is the Cummins X15 engine rated at 447 kW (608 hp). Compliant with the European Stage V regulation, it stands out for an architecture featuring a Variable Geometry Turbocharger (VGT) and the patented XPI fuel injection system, which enable very high maximum torque values of up to 3,200 Nm. These are fundamental for smoothly tackling the high stresses imposed by milling operations.

As for Stage V compliance, it features several abatement systems for both fine particulate matter (PM) and nitrogen oxides (NOₓ):

• Diesel Particulate Filter (DPF), which reduces ultrafine dust emissions with an efficiency higher than 99%;
• Selective Catalytic Reduction (SCR) with AdBlue/DEF injection, which reduces NOₓ emissions down to the required standards;
• Diesel Oxidation Catalyst (DOC) and an active/passive filter regeneration system.

Transport Dimensions

With a length of 12.6 meters and a height of 3.0 meters, the machine falls within the dimensional limits for lowboy trailer transport on European roads. However, this does require the necessary permits for oversize/overweight transport due to the overall weight. Finally, the transport width of 2,500 mm is compatible with standard gauge transport regulations.

The Milling Drum

Unveiled at SaMoTer Verona, the milling drum of the XM2005K has a working width of 2,000 mm and can operate down to a depth of 330 mm in a single pass. This value stands at the top of the market, allowing the removal of multi-layer road packages without the need for multiple deep passes.

The drum is driven by a high-efficiency multi-belt transmission system. This system not only reduces power losses between the engine and the rotor itself but, thanks to the presence of three belts working in parallel, allows for greater operational autonomy in the event of a belt breakage. In fact, XCMG developed this system specifically to ensure that, in case of an unexpected breakage of one of the belts, the ongoing milling operation can still be completed. The milling teeth are mounted on an interchangeable, highly wear-resistant steel toolholder. This choice facilitates on-site maintenance and extends the service life of the rotor. The spiral distribution naturally ensures an even advance of the milled material toward the center of the rotor, and from there toward the primary conveyor belt.

Quick Drum Change

It is also possible to equip the machine with different drums that feature different tooth pitches. Replacement is carried out using a quick-attach and quick-release coupling system. This makes it possible to optimize the surface finish based on the type of application. A reduced pitch produces a finer surface suitable for applications where residual roughness is critical. Conversely, a larger pitch favors hourly productivity during deep scarification. Furthermore, the moldboard blades of the milling chamber consist of segments rather than a single component. On one hand, this allows them to be replaced or rotated by a single person due to their reduced weight. On the other hand, it is also possible to replace just a single element when, due to factors related to a specific application, it is more worn out than the others.

What’s XCMG

XCMG (Xuzhou Construction Machinery Group) is one of the world’s leading manufacturers of construction and road equipment. The company currently ranks fourth in the Yellow Table, the annual ranking of the world’s largest construction equipment manufacturers. Founded in 1943 in Xuzhou, Jiangsu Province, China, XCMG has developed a broad product portfolio covering cranes, excavators, asphalt pavers, road rollers and other construction machinery.

Within its road equipment offering, the cold milling machine range extends from compact 500 mm cutting-width models to large 2,000 mm-class machines, including the XM2005K.

Is rapid drum replacement possible?

The machine can be equipped with different milling drums, each featuring a specific tool spacing. Drum replacement is carried out through a quick-release coupling system, allowing the machine to be configured according to the application and the required surface finish.

A closer tool spacing produces a finer surface texture, making it suitable for applications where the residual surface roughness is a critical parameter. Wider tool spacing, by contrast, maximises hourly productivity in deep milling operations.

The milling chamber scraper blades are also designed as segmented components rather than a single one-piece assembly. This allows a single operator to remove, rotate or replace each segment thanks to its lower weight. In addition, individual segments can be replaced independently whenever a specific area is subject to higher wear due to particular operating conditions.

What is the integrated water spray system?

The integrated water spray system suppresses dust by spraying a fine mist onto the milling drum and the material discharge area. Any remaining dust is extracted at the discharge conveyor and directed towards the ground, reducing airborne particles around the machine.

The onboard water tank provides sufficient capacity for standard milling operations. With a capacity of 3,000 litres, it is equipped with a fast-fill system to minimise refilling time on site.

In addition to dust suppression, the water spray system cools the milling tools, helping to reduce wear and maintain consistent cutting performance throughout the operation.
