Indiabulls takes four tower cranes

Developer and contractor Indiabulls has invested in four Liebherr tower cranes for the new Greens Township in Chennai, southern India. The cranes have been purchased from Liebherr CMCTEC India by Store one Retail Ltd (SORIL), an Indiabulls Group company.

The four Liebherr 71 EC-B 5 flat tops are being used on what could be a 10 year development project built by Indiabulls on 15 acres of greenfield land within the IT belt of Chennai.

Indiabulls has invested in four Liebherr tower cranes for the new Greens Township in Chennai, southern India.

The first phase of the project - a series of six-storey apartment blocks - was built with the help of Chinese branded tower cranes and topped out in July this year. Phase II consists of 11 blocks, each 19 storey’s high.

"The Liebherr cranes are intended for use throughout the remainder of the project, which as planned could well have a construction phase of 10 more years," says Chandran Raja, Indiabulls's plant and equipment manager at Greens.

The 11 blocks of Phase II are being built in four blocks at a time, with one crane deployed for each block. The four blocks will be completed simultaneously and the cranes moved onto the next blocks. The height of each storey is 3 metres, with the total height of each block being about 60 metres.

"We are using the cranes as external climbing units," he says. "They have a hook height of 41.5 metres. We will need to extend the height of the cranes once to give ourselves the final under-hook clearance."

All the required accessories and tower sections were supplied by Liebherr to achieve a 70 metre hook height. The 71 EC-B 5 units each have the standard 50 metre jib, with a one tonne capacity at the jib tip. Maximum capacity is five tonnes.
