  • Nominal torques from 100 kNm to 800 kNm


Increased lifting distance

Due to unique design longer axial strokes are available.

  • Stroke from 300 mm up to 1000 mm

Torque support

Two torque supports connected by torsion bar allow full self-alignment of speed reducer.


Ease of maintenance

Sliding motion during axial movement occurs outside gearbox in standard spherical plain bearings. Not inside housing requiring costly spare parts.
