Liebherr has expanded its range of flat-top cranes with the 300 EC-B 12 Fibre and 270 EC-B 12. Both machines are designed for sites requiring heavy hoists and meet all the main requirements placed on a modern crane fleet.
The 300 EC-B 12 Fibre features the company’s fibre rope, has a 70-metre jib and delivers a lifting capacity at the jib head of 3,250 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 2,850 kilograms. The new cranes replace the existing Liebherr 250 EC-B and 278 EC-B Fibre models.
The “Tough Guys” have been designed for simple transport and erection. The counter-jib, slewing platform and jib segments can be carried to the site in just four transport units and feature the company’s quick-release connectors.
Both machines have a 21 HC 290 tower connection. This tower system, which measures 2.1 x 2.1 metres, enables a maximum free-standing hook height of 71.5 metres. The 24 HC 630, with dimensions of 2.4 x 2.4 metres, enables a maximum free-standing hook height of 91.7 metres to be achieved.
The LiCAB crane operator’s cabin features an ergonomic control stand and large glass windows. The cabin also includes a newly developed 12-inch display with intuitive control. 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 per cent increase in lifting capacity), Micromove (fine positioning of loads) and ABB (operating-range limiting system) support the crane operator and enable them to hoist loads safely.
