Takraf_smallNeyveli Lignite Corporation Ltd, a Government of India enterprise, has inducted two state-of-the-art bucket wheel excavators with an operating capacity of up to 6,800 cubic metres per hour for their Mine-II project in Tamil Nadu. The new bucket wheel excavators were inaugurated last month in the Mine-II site by NLC CMD B. Surender Mohan.

The bucket wheel excavators of 1,400 litre capacity were erected and supplied by Takraf India Ltd, Chennai, in collaboration with Takraf GmbH, Germany. These giant crawler mounted excavators, each weighing close to 2,600 tonnes, will be used in NLC Mine-II area for removing the overburden or top soil over the lignite deposit. The maximum cutting height of the machine is 30 metres.

This is the first time in NLC history that two excavators of such large size were put into service at the same time. The project was completed five months ahead of the tight schedule. Takraf India executed the project on a turnkey basis.

The continuous mining technologies for open pit mines developed by Germans have been successfully used by NLC for several decades, besides providing the advantage of low cost of lignite mining.
