The Komatsu-style belt tensioner is made from alloy steel with 55 Rockwell C hardness, weighing approximately 12 kilograms. Its total body length is 350 millimeters with a 30-millimeter rotating shaft diameter. The internal spring is loaded with 550 N to maintain consistent belt tension under high dynamic conditions. The surface is heat-treated and coated against corrosion, allowing stable operation at temperatures ranging from -20 to 80 degrees Celsius.
The belt tensioner offers precise adjustment of ±3 millimeters and a response time under 0.15 seconds. Installation on construction and mining machinery is done with M12 bolts. The internal gear and lever design ensures uniform force distribution on the belt, reducing vibration and wear during prolonged operation. Routine maintenance is simple, and replacement of wear parts takes under 10 minutes.
