R & D

R&D activities were started in KGF & Bangalore divisions during mid 70’s and at Mysore during mid 80’s. The initial focus was on Technology absorption and indigenisation. Subsequently products and aggregates were taken up for design and development.

Fully equipped R&D Centre with facilities for design, simulation and testing was established in 1984 at KGF with an investment of INR 50 crores and further upgraded over the years, and is one of the biggest development centres in India. R&D Centres at KGF, Mysore & Bangalore are recognized by the Department of Science & Technology, GoI. This Centre is making vital contribution towards strengthening the Earthmover and related industries in the country. R&D Division is equipped with CAD Centre and dedicated Laboratories in the areas of Fluid Power, Power Train, Structural Engineering and Material Science.

R&D division is manned by highly qualified engineers with specialisation in advanced fields of mechanical design, engine technology, structural engineering, material science, fluid power and electronics and have gained significant experience and technical knowhow in design and development of complete machinery as well as the aggregates.
