The purpose of this study was to design and manufacture the safety conveyor device in treadmill maximal tests. This device was designed and manufactured considering the subject not falling off the treadmill, and not getting injured during a maximal test. First, the safety conveyor device, was made in small sizes of ۳۰ cm as a prototype before, so that the size of the device can be examined and evaluated realistically. Then a sample was made with iron alloy. The results indicate that the safety conveyor device in the prototype did not have the ability to withstand overload, however after strengthening the conveyor device protector, it acquired the ability to maintain the overload. The safety conveyor device, which has the ability to open and close, prevents the subject from falling and getting injured during extreme tests.
