The single-column tensile test machine is used to determine the mechanical and physical properties of materials under conditions such as tension, compression, bending, shearing, tearing, peeling, and puncture. During the exhibition, this equipment drew significant attention due to its ease of operation and high flexibility, earning widespread recognition.

This device is used to determine the crack index of shoe uppers, leather surfaces, and various thin leathers. The specimen is fixed in clamps, and a ball is pushed into the leather at a speed of 12mm/min. When the leather cracks, the value of the increased height is the crack value.
