For more than 125 years, Robel has been developing and manufacturing track construction machines - always aspiring to be a pioneer in terms of safety, sustainability and innovation.

The close proximity to our customers enables us to recognize current challenges, develop needs-based solutions and transform them into new technologies and products. Customer satisfaction, user safety, economic efficiency and our responsibility towards the environment are at the heart of what we do. Many years of experience in track machine construction allow us to offer a full set of railhead treatment solutions available to markets worldwide. Simply by users for users.

The challenge

Increasing ridership, higher speeds and volumes of cargo as well as high track utilization put enormous stress on rails and switches and accelerate the wearing process. Rail defects such as cracks and corrugation are the result. These lead to a shorter rail service life, contribute to higher noise levels, reduce ride comfort and pose a significant safety risk.

The solution

To meet the growing demands on rail systems and minimize the associated costs and risks, a sustainable and efficient rail maintenance procedure is needed. ROBEL's rail treatment solutions combine state-of-the-art milling, grinding and measuring technology and restore the rail profile. With a single pass, defects are measured and the rail is milled and polished. The wheel-rail contact is optimized and the rail service life is increased. Our worldwide all-round service on-site supports you throughout the entire maintenance process and beyond.
