In July 2024, TAKRAF India was awarded the contract for major refurbishment of two 700 L bucket -wheel excavators (BWEs) for two mines.
The BWE 700, a Specialized Mining Equipment (SME), originally commissioned at NLCIL in 1990 for overburden and lignite removal, was successfully recommissioned by TAKRAF India on 30th September 2025. This marks the first major revamp for NLCIL for any 700 liter BWE.
NLCIL, incorporated in 1956, is a public sector company of the Government of India and one of the country’s largest lignite and power producers. As a Navratna entity, NLCIL has also been bestowed a prestigious status given to only a few select Indian Public Sector Undertakings (PSUs), and as such has enhanced financial autonomy. NLCIL operates three open pit mines with a total installed capacity of 28.5 MTPA at Neyveli, Tamilnadu, India.
This 700-liter BWE has completed over 160,000 working hours during its 34-year working life cycle. To extend its operational life, NLCIL decided to undergo a major refurbishment, replacing all critical structural and mechanical components. TAKRAF India was entrusted with the work, which was scheduled to take 12 months from engineering to commissioning.
The upgrade incorporated advanced technologies, such as structural stability checks, upgradation of drive power ratings, replacement of age old obsolete components with latest technology adapted components, the introduction of a PLC (Programmable Logic Controller), VVVF drives (Variable Voltage Variable Frequency drives), an HMI (Human-Machine Interface), an AFDQS (Automatic Fire Detection and Quenching System) and wireless systems and cloud based remote monitoring systems. These upgrades are following DMS safety norms (Design & Manufacturing Safety norms) and increase the machine’s life by about 15 years.
Shri Prasanna Kumar Motupalli, Chairman and Managing Director of NLCIL, recommissioned the revamped BWE 1573 in the presence of Dr. Suresh Chandra Suman, Director of Mines; Shri. M. Venkatachalam, Director of Power; Thiru. Appakannu Govindarajan, Chief Vigilance Officer, and TAKRAF India Managing Directors Gopal Kalyanakrishnan and Rajagopalan Ramanathan, alongside NLCIL and TAKRAF India employees.
“The fourth consecutive order from NLCIL highlights the strength of TAKRAF India’s collaboration with TAKRAF Germany and our dedication to providing customized, project-specific solutions through effective teamwork.”, says Rajagopalan Ramanathan, Managing Director of TAKRAF India.
