ATI Inc. is a privately owned and operated company whose owners have been involved in tracks for over 30 years. They began serious development of rubber track systems in the early 1990’s before establishing ATI in 1997. After 4 years of design and development the first units were sold in 2001 for seismic exploration on Alaska’s North Slope. These units have continued to operate successfully and have accumulated 12,000-15,000 hours each. Throughout it’s history there have been other very successful applications of ATI’s standard track due to the simple, rugged design and quality manufacturing processes. The market need for even greater mobility was recognized leading to development of the High Idler Module concept. This concept built on all the inherent advantages of the standard module but added an aggressive attack angle allowing the module to climb over most difficult terrain conditions.
