Designed and built by Foremost Industries who are based in Alberta, Canada, the Husky 4 flotation undercarriage is normally designed to be fitted to a Cat 320 excavator, but as seen in this video can be fitted to other excavator manufacturers machines, in this instance a Daewoo 225 model.
The undercarriage which has a ground bearing pressure of just 3.3 PSI provides increased flotation over adverse terrain conditions where conventional excavators would easily become stuck.
