Liebherr’s most powerful flat-top NC-B crane, the NC-B 12-70, has been put to work in Medina, Saudi Arabia, on a museum construction project. The crane’s 12-tonne lifting capacity and 70-metre (230-foot) reach, with a freestanding hook height of up to 76.9 m (252 ft) make it ideal for cast-in-place concrete construction, which requires precise lifting of heavy prefabricated parts. The Medina site is in the midst of high-traffic roads and tall neighbouring buildings, leaving a tight work space for the crane, but the NC-B 12-70 has a jib head load capacity of 2,000 kilograms (4,400 pounds) at maximum jib.

Quick Assembly

NC-B cranes are optimised for transport and assembly. Five trucks deliver all elements of the slewing part with 70 m jib length to the site and can be transported in standard containers. When it comes to assembly, the central unit with slewing platform and connection element require only one lift and a weight reduction of the central unit is possible. The slewing platform, control cabinet, and cabin can be installed separately if needed. The flat-top crane’s assembly is further accelerated by LiConnect, Liebherr’s quick-connection system that allows the jib to be assembled in 5-m (16-ft) sections.

Special Features

The NC-B 12-70 is compatible with the 16 EC 240 tower system, which is designed expressly for use with NC-B-series cranes, as well as the 21 HC 290 system. The hydraulic climbing unit is suitable for both internal and external climbing and is completely detachable and compatible with other Liebherr tower cranes. The hoist gear, slewing gear, and trolley are controlled by a frequency converter to ease stepless acceleration during lifting, lowering, and slewing. Drive units with frequency converter also minimise the risk of damage to the crane. The crane also features the Micromove smart assistance system, which ensures exact positioning of heavy loads.
