After the launch of the Liebherr NC-B series last year, the cranes are already working on several construction sites. One of them is the Balewadi Techpark in Pune, India. The NC-B 6-62 is exhibited at booth OD 50 at Excon.
The Balewadi Techpark Pune, a part of the 2.2 million sq. ft. of Panchshil Business Park, offers shoppers a varied option of 23 high-end retailers. With cutting-edge design, it will be an incredible fusion of design, art, fashion, food, leisure and business. Altogether, the commercial building will cover two basements, the ground floor and 16 stores.
Based on the its experiences with two 85 EC-B 5i last year, S.J. Contracts Pvt. Ltd. is now deploying two NC-B 6-62. Both the cranes are used as internal climbers due to the height of the building: 83.3 m. At a 35 m working radius and up to 3.40 t, building material has to be lifted, that’s mere child’s play for the two NC-B 6-62. At 35 m working radius, it can still lift 3.92 t. With the 50 m jibs, the cranes can easily cover the whole construction site.
The Flat-Top cranes are used for the climbing formwork of the building and therefore have tower heights of 46.80 m with an overhang required of around 18 meters at any moment of construction progress. Actually, the NC-B 6-62 was achieving 21.7 m. Consequently, it needs less climbing steps. That accelerates the whole building process. The assembly of the cranes was in June 2017, and in the end of 2018 the building is supposed to be finalized. Liebherr has exhibited a NC-B 9-62 at the Excon in Bangalore.
The NC-B series
The NC-B series was specifically developed to meet the requirements for use in conurbations in emerging countries. The first two models in the 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 new 16 EC tower system with external dimensions of 1.60 m x 1.60 m was developed for the new NC-B cranes. These tower sections are climbable and connected by using pins. The hydraulic unit is suitable for both internal and external climbing. It can be removed in full and is compatible with other Liebherr tower cranes of the same crane class, which means that operators only require one unit which can then be used at different sites.
The model names of the NC-B cranes indicate its maximum lifting capacity and maximum radius. The NC-B 9-62 model on show at the Excon India therefore has a maximum lifting capacity of 9 tonnes and a maximum radius of 62.50 m.
