After years of engineering development and large-scale field testing, Global Air Cylinder Wheels (GACW), the Phoenix-based developer of the Air Suspension Wheel (ASW), has announced a key milestone in the transition from research and development to commercial deployment for 2026, following successful extreme-condition validation trials in Minnesota mining operations.
The recent winter trial subjected the company’s non-pneumatic mechanical wheel system to real-world operating conditions in Minnesota in December, with temperatures ranging from approximately -29°C to -40°C under full production loads and operational conditions. The testing focused on validating suspension performance, tread compounds, lubrication systems, and traction in extreme sub-zero mining conditions.
