General Drive Technology

Compact drives with high energy efficiency: This is en essential trend of general drive technology in mechanical engineering. More and more frequently electric drives are speed-controlled with competition among the individual drive technologies (electromechanical, hydraulical, pneumatic) encouraging the suppliers‘ innovative strength. The result of digitization is that the drives are more and more often integrated in superordinate communications networks.

KTR provide mechanical engineering with a wide range of drive components and systems covering four business segments: mechanical couplings, brake systems, cooling systems and hydraulic components. KTR set standards in these fields over decades again and again while advancing drive technology.

Perfectly organized logistics, worldwide presence with 24 subsidiary companies and more than 90 distributers as well as an international network of 8 production sites create the prerequisite for rapid delivery capability of the overall standard range.

Speedy advice and service with competent and individual support are ensured – in more than 65 countries.
