Gurgaon/Delhi (India), January 2017 – At the Bauma Conexpo India show held in December 2016, Liebherr unveiled a new series of top-slewing cranes with a flat-top design – the NC-B cranes. The new 16 EC tower system has been developed for these cranes. The cranes also have a new, variable climbing system. The new concept includes a large number of time-tested elements from existing Liebherr top-slewing cranes.

The new NC-B series was specifically developed to meet the requirements for use in conurbations in emerging countries. The first two models in the new series can cover a wide range of construction projects in these areas. The nine-tonne version is ideal for hoisting heavy prefabricated components – for example for building shopping centres, production plants and car parks. The six-tonne NC-B 6-62 crane, meanwhile, is perfect for erecting tower blocks in inner city areas where they work with low load weights but enormous hook heights.

The model names of the NC-B cranes indicate their maximum lifting capacity and maximum radius. The NC-B 6-62 model showed at the Bauma Conexpo India therefore has a maximum lifting capacity of 6 tonnes and a maximum radius of 62.50 m.

Liebherr manufactures cranes tailored to suit the local market in India at its Liebherr CMCtec India Private Limited site opened in 2012 in Pune, ensuring short lead times whilst still using time-tested, high-quality German technology.

The new 16 EC tower system with external dimensions of 1.60 m x 1.60 m was developed for the new NC-B cranes. As usual with tower systems in these classes, the tower sections are connected using pins and are climbable. The standard length of the tower sections is 3.90 m. Extended tower elements with a length of 11.70 m can also be used to reach a maximum free-standing hook height of 53.20 m quickly and at low cost.

The hydraulic climbing unit is suitable for both internal and external climbing. It can be removed in full and is compatible with other Liebherr tower cranes, which means that operators only require one unit which can then be used at different sites.
