Italy-based gear box manufacturer Bonfiglioli Transmissions is planning to spend about Rs 75 crore on the expansion of its Chennai plant, by 2010.

The company said that fresh investment to be met through internal accruals would be for plant and machinery.

Earlier, the company had invested Rs 400 crore in the Thirumudivakkam facility, near Chennai.

The company manufactures equipment for windmill application in India. In addition, it caters to industries such as machine tools, pharmaceutical, sugar, cement and construction.

Last year, company's Indian unit contributed Rs 310 crore to the group's turnover.

According to reports, the current domestic industrial gear box market was estimated to be around Rs 1,500 crore, out of which Bonfiglioli's share stood at around 16 per cent.

The company is aiming to achieve a market share of 25 per cent in the near future.
