This is a new concept green treadmill developed by our company independently, which adopts an elastic rubber arc running deck, crawler runningbelt lamination technology. Using gravity to start, accelerate and decelerate and controlling the speed freely, the product overcomes the impact to the knee due to the failure of footsteps to keep up with therunning belt in passive running, radically puts an end to the traditional electric “passive” runningway and realizes “active” running in the real sense. The arc running surface, crawler elasticrubberrunning belt and active running design reduce the impact during movement and effectivelyprotect the runner’s knees, while the bearing drive system reduces movement wear and lowers the maintenance costs.
