This New YellowFOX Tunnel Excavator from Wimmer Is Pretty Darn Cool

Wimmer Hartstahl, a leading manufacturer of tunnel excavators, recently announced the latest addition to its excavator series — the YellowFOX. This new machine joins the existing Blue Badger, eBadge, and miniBadger lineup — all of which have been designed explicitly for smaller tunnel cross-sections.

The YellowFOX is a highly flexible and efficient machine, capable of working at heights from 13.7 ft. It is built on a specially made Liebherr platform, featuring a Liebherr 914 Compact Litronic superstructure and a Liebherr 920 Compact Litronic undercarriage. This is not a standard platform but a custom version exclusively designed for Wimmer. The excavator boom, like the Badger family, is also custom-made by Wimmer.

Key features of the YellowFOX include a breakout force of 120 kN and a tear force of 115 kN. It has an operating weight of approximately 22 tons and an engine power of 120-hp Tier IV Final Stage. The boom can be swivelled by 45° and features a push rod to allow the cylinder to be concealed and protected.

“YellowFOX’s advanced technologies will undoubtedly enhance the performance and productivity in the mining industry,” said Josh Caouette, President of Evolution Mechanical. “As exclusive distribution partners, this further solidifies our position as a Canadian heavy equipment market leader. We look forward to bringing the new tunnel excavator to our customers across Canada and all other Wimmer products.”

The YellowFOX incorporates intelligent technology made in Thalgau, ensuring high efficiency and flexibility. Regarding safety equipment, the YellowFOX has an integrated fire extinguishing system, an emergency stop button, and an optional Blaxtair person detection system. Standard equipment includes a central lubrication system, a reversible fan, a 2-grouser bottom plate 500 mm with a chain scraper, a refuelling pump, and fire-resistant hydraulic oil (PAG).
