New 300 EC-B 12 Fibre and 270 EC-B 12: EC-B series from Liebherr continues to grow

Biberach (Riss) (Germany), 15 July 2022 – The 300 EC-B 12 Fibre features the Liebherr fibre rope and therefore delivers significantly better performance values than similar cranes with a steel rope. The fibre rope also has a much longer service life which means that the rope has to be changed less frequently. That makes operation even more economical and increases the crane’s availability. The 300 EC B 12 Fibre has a 70 metre jib and delivers a lifting capacity at the jib head of 3250 kilograms. The steel rope version of the 270 EC-B 12 with a 70 metre jib has a lifting capacity at the jib head of 2850 kilograms. Powerful hoist units and pure 2 line operation make both machines particularly efficient. The new cranes will replace the existing Liebherr 250 EC-B and 278 EC-B Fibre models.

Fast, safe erection

The “Tough Guys” have been designed for simple transport and erection, which also delivers major cost benefits for rental businesses. The counter-jib, slewing platform and jib segments can be carried to the site in just four transport units due to their smart stacking system. This also makes a major contribution to reducing greenhouse gases. The jib and counter-jib can be attached to the slewing platform easily, conveniently and safely. This is all made possible by Liebherr’s time-tested quick-release connectors. Depending on the requirements at the site, the jib can be extended or reduced in 2.5 metre sections.

Both machines have a 21 HC 290 tower connection. This tower system, which measures 2.1 x 2.1 metres, is the perfect choice in terms of performance and economy. It enables a maximum free-standing hook height of 71.5 metres. The 24 HC 630 (dimensions: 2.4 x 2.4 metres) enables a maximum free-standing hook height of 91.7 metres to be achieved.

Everything in clear sight – the crane cabin with TC-OS

To ensure safe crane operation, it is essential that the crane operator has a perfect view of the crane and site at all times. The LiCAB crane operator’s cabin features an ergonomic control stand and large glass windows which deliver perfect visibility. The cabin also includes the newly developed 12 inch display with its intuitive control concept. The Tower Crane Operating System (TC-OS) provides crane operators and erection engineers with special menus, a large selection of languages and readily understandable dimension units. Furthermore, smart assistance systems such as Load Plus (up to 20 percent increase in lifting capacity), Micromove (fine positioning of loans) and ABB (operating-range limiting system) support the crane operator and enable him to hoist loads safely.

The 300 EC-B 12 Fibre and 270 EC-B 12 fit seamlessly into the successful group of “Tough Guys” with their strong performance, flexibility and economy. From a small city crane to a large handling expert – EC-B cranes cover a wide range of operations. And due to their design, multiple flat-top cranes can operate on constricted sites without any problems.
