Abstract
There is disclosed a device having a supporting frame with a slot forming a gap in one leg of the frame. A stationary and a rotatable shaft are positioned in the frame on opposite sides of the gap. A belt sample is attached to the shafts and a ratchet assembly applies progressively greater strain on the belt sample. The level of strain is measured by a load cell placed across the gap in the frame to yield a value for the ultimate tensile strength of the belt being tested. The device is portable and provided with a handle serving as a lever for applying progressively greater strain through the ratchet assembly. The device is used to compare the relative strengths of conveyor belting samples at a field location.
