For us, having decades of experience in stone crushing is a commitment. The design and construction of the single-jaw crushing units shown here are based on this principle: strong machines for heavy loads.


  • Suitable for reducing stones with a compressive strength of approx. 3000 kg/cm²
  • Crusher housing and swing jaws are welded from the best steel and thermally annealed
  • Carefully calculated dimensions with the appropriate safety margins
  • Strong eccentric shaft made from the best heat-treated steel and carried by four heavy dust-protected barrel-shaped roller bearings




  • Hydraulically pressed clamping sleeves on the bearings for a better fit and to make changing easier
  • Crusher jaws with surface-ground backs made from electric straight manganese steel provide the optimum contact: the crusher jaws can be turned for maximum utilisation
  • Hydraulic cylinders to adjust the gap width. High performance even with a narrow gap width thanks to the favourable entry angle
  • Flywheels with cast-on counterweights and firmly attached to the eccentric shaft by special clamping elements
