Custom Built Heavy-Duty Gearboxes for Opencast Mining

The Kumera Custom Built Gearbox and Drives portfolio includes the design and manufacture of gear wheels up to diameter of up to 4.0 m and gearboxes from medium range weighting up to 300 tonnes

Especially in open-cast mining, we continuously combine experience with new scientific findings. On this basis, we develop gearboxes with a drive force of 2500 KW and larger, which set standards in terms of sealing and lubrication concept. However difficult the conditions may be, our heavy duty workers perform first-class, due to their robustness and particularly low maintenance. In motor use in belt, paddle wheel, drive or swivel gear transmissions as well as in generator mode.
