The Xie Shan is tailored for long-term load-bearing mobile operations. It utilizes a four-bar linkage bionic structure matching the knee's trajectory to realize climbing,rolling, and maneuvering over complex terrains. It redirects over 70% of the shoulder load to the back frame, greatly alleviating load-bearing muscle fatigue. The quick-release components allow users to don/doff the device within 45 seconds, enabling rapid response to emergency rescue tasks.
