In 2013, KAISER and MBA AG agreed to enter into a collaboration in the area of road-rail excavators. The rail and machine construction know-how of the two companies, combined with KAISER’s capabilities as an experienced construction machine manufacturer, provided the ideal basis for the development of a modern dual-mode excavator. The joint development was aimed at a short-tail road-rail excavator with the engine power to enable the optimal use of ballast tampers, ballast brushes and other attachments.

The manufacture of the S22RR takes place at KAISER in Liechtenstein, and KAISER is also the point of contact for international markets, while MBA is responsible for distribution in Switzerland. MBA AG, based in Bassersdorf, is a leading supplier of construction machines in the Swiss market. Rail construction has long been a cornerstone of the company’s wide-ranging portfolio, which includes construction machines for infrastructure in the building sector. The name MBA stands for “Maschinen und Bahn AG” (machines and rail). Continuous adaptation to meet the requirements of standards, safety and efficiency, bolstered by MBA’s specific expertise in rail construction, has made the company a reliable partner in this field. The new S22RR road-rail excavator was launched onto the market in 2015/16. The sales success achieved to date reflects the trust that customers place in the two companies, MBA and KAISER.
