To imitate the effects of running time and time again, our SportsArt test lab developed a robotic “treadmill tester” — which is basically a 500 lb (226 kg) octopus. This machine runs on the treadmills for 5 hours around the clock at a speed of 5.5 mph (8.85 kph), with only an hour break in between each stint. The combination of high-impact, heavy foot plant speed and the simulation of a heavy user allow us to test the deck, roller bearings, and belts for wear, as well as the motor for heat.
The combination of high-impact, heavy foot plant speed and the simulation of heavy user allow us to test the deck, roller bearings, and belts for wear, as well as the motor for heat build-up and amp draw when under extreme stress. In order to pass this test, component life must exceed 15,000 miles (24,140 km) — roughly 10 miles per day for 4.5 years.
