Erkat V-Series Drum Cutter: versatile milling under diverse conditions

In the world of demolition, infrastructure, and earthmoving, the success of a project often depends on choosing the right attachment. For milling trenches, working asphalt, and excavating soft rock or frozen ground, the Erkat V-Series offers a drum cutter designed for productivity and uptime.

What makes the V-Series suitable for heavy-duty work?

The Erkat V-Series is a drum cutter for excavators with an operating weight between 15 and 40 tonnes. This makes the Erkat V-Series available for a wide range of machines deployed daily in demolition, cable and pipeline work, tunnelling, and earthmoving.

The strength of the cutter lies in the combination of a high-torque radial piston motor and a robust bearing and gear system. The motor delivers the torque required to keep cutting through difficult material without losing rotational speed, while the load-resistant bearing system and reinforced gears ensure efficient energy transmission from motor to drum. The result is higher productivity per hour and a longer service life for the drivetrain.

In addition, the drums within the V-Series have been developed in a V-shape. This geometry minimises the space between the drums, allowing material to be picked up and discharged more efficiently. This results in a more consistent cut and a higher production capacity per rotation, especially during continuous milling work in tough conditions

The housing is made of HARDOX steel, because in milling and cutting work in concrete and rock, the housing is the first component to absorb wear. A robust construction translates directly into more uptime and lower maintenance costs over the lifespan of the attachment.

Technical features

• QuickSnap pick holder system: This provides optimal pick clearance on the VC 3600 through VC 8300 models and makes changing worn picks faster and easier.
• High-torque radial piston motor: Delivers constant power under load and increases productivity, even in hard or frozen material.
• 360-degree rotation: The attachment can be positioned in any orientation, increasing precision during trenching, profile milling, and working in confined spaces.
• Submersible up to 30 metres: Suitable without modifications for applications in hydraulic engineering, ports, and wet trenches.

Hatcon monitoring system

The V-Series can be equipped with the Hatcon monitoring system. This allows the performance of the attachment to be tracked in real time: load data, operating hours, and deployment status are immediately accessible. For fleet managers and project supervisors, this means better-timed maintenance and a longer effective service life of the machine.

Applications in practice

The drum cutter is broadly applicable:

• Trenching for cable and pipeline trenches in urban areas, where low-vibration work is important.
• Asphalt milling during roadworks and tie-ins.
• Excavating soft rock in foundation work and infrastructure.
• Frozen ground during cold periods, where conventional buckets get stuck.
• Underwater applications up to 30 metres deep, such as rock excavation.

Precisely because the Erkat V-Series operates with low noise and low vibration compared to hydraulic breakers, an Erkat drum cutter is an ideal choice for projects in built-up areas or close to existing structures. With a broad product range and technical support from SAES, users are assured of a reliable and productive solution for every demolition challenge.
