Tata Hitachi Construction Machinery Co will pump in around Rs 200 crore on R&D and upgradation of its Kharagpur plant in West Bengal even as it expects profit to be hit by slowing demand this fiscal. The joint venture between Tata Motors and Hitachi Construction Machinery, hopes the new investments will help it tide over the dependence on imported materials. At present, imports account for at least 50 per cent of the components manufactured at its three plants  Kharagpur, Jamshedpur (Jharkand) and Dharward (Karnataka).
