300 EC-B 12 Fibre and 270 EC-B 12 replace the 278 EC-B Fibre and 250 EC-B models.

Liebherr is expanding its series of flat-top cranes with the new 300 EC-B 12 Fibre and 270 EC-B 12. According to Liebherr, both machines are ideal for sites requiring heavy hoists and meet all the main requirements placed on modern cranes.

The 300 EC-B 12 Fibre uses Liebherr’s fibre rope which the company says delivers significantly better performance values than similar cranes with a steel rope. The fibre rope also has a longer service life, claims Liebherr, meaning it needs less changing. 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.

Both cranes have powerful hoist units and two-line operation for greater efficient. The new cranes will replace the existing Liebherr 250 EC-B and 278 EC-B Fibre models.

The cranes have been designed for simple transport and erection with the counter-jib, slewing platform and jib segments being able to be carried to the site in four transport units due to their smart stacking system. The jib and counter-jib can be attached to the slewing platform using Liebherr’s 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, which measures 2.1 x2.1 metres. It enables a maximum free- standing hook height of 71.5 metres. Alternatively, a 24 HC 630, which measures 2.4 x 2.4 metres, can be specified which enables a maximum free-standing hook height of 91.7 metres. The cranes use Liebherr’s Tower Crane Operating System (TC-OS) which provides crane operators and erection engineers with special menus, a large selection of languages and dimension units. It includes smart assistance systems such as Load Plus (up to 20 percent increase in lifting capacity), Micromove (fine positioning of loads) and ABB (operating-range limiting system).
