Liebherr has introduced new crane series to provide the crane operators with a better overview of the construction site, which is a crucial aspect for site safety
The first eight units of the new series already cover a wide range of services ? from small city to large handling cranes. As a result, the maximum load capacities range from 6 to 16 tonnes and the maximum jib head load capacities range from 1.6 tonnes to 2.8 tonnes ? working at a maximum radius. At full jib length, the units are among the largest in their class. The 125 EC-B 6 itself reaches 58 metres. The two largest cranes in the series, the 340 EC-B 12 and the 370 EC-B 12 Fibre each have a reach of up to 78 metres. In addition, all cranes are optimised for assembly.
New models with fibre rope feature that has four times longer service life than steel rope and enables fibre cranes to work with significantly higher load capacity.
When developing the new series, the construction machinery manufacturer also focused on the comfort of crane operators and safety on the construction site: The new LiCAB cabin is significantly larger and also has a greater field of vision. In addition, the new top-slewing cranes have a new, central control element: a multi-touch display. Last but not least, a new design with integrated advertising panels guarantees an improved impact over distance.
Particular highlights of the new EC-B series are the 240 EC-B Fibre and 370 EC-B Fibre cranes. These are equipped with soLITE high-tensile fibre rope, which has been developed more than a period of 10 years by Liebherr and the rope manufacturer Teufelberger.
Increased comfort
With more than two square metres of space, the new cabin has more room than any EC-B cabin before. Because of its larger field of vision, crane operators have a better overview of the construction site ? a crucial aspect for site safety.
As well as ergonomically positioned operating elements, crane operators will find a variety of storage options and surfaces ? including details like a cup holder. As well as this, the new cabin has several power sockets to plug in small electrical appliances such as a kettle or radio equipment. In addition to the standard 230 V sockets there are also USB interfaces to provide power for items such as smartphones.
The new 12-inch multi-touch display ensures all devices in the cabin are networked together. This means that all control settings such as scaling via the newly developed scaling assistant, setting the enhanced ABB operating-range limiting system and using the trolley camera can all be done via the display.
The cabin is available in three options: The LiCAB Basic, the LiCAB Air with air conditioning, and the premium LiCAB AirPlus version with air conditioning, double glazing and tiltable side windows.
Optimised steelwork
The new EC-B?s compact head, jib and trolley are lighter than their predecessors. In addition, the jib is now so narrow that three jib sections fit onto a truck bed. Compared with similar Liebherr cranes, even the shortest jib requires one whole transport truck less ? and at least two less at maximum radius. This saves both time and money.
The new EC-B series makes optimal use of the tower systems? performance capacity. Even the currently largest, new EC-B, the 370 EC-B 12 Fibre, works using the 21 HC 290 tower system with corner posts measuring only 2.1 metres. This is particularly interesting as it is one of the most widely used Liebherr tower systems.
Liebherr has also developed a new tower system, the 12 EC 125, for the 125 EC-B 6 as part of the new series. With its extremely slim corner posts measuring 1.2 metres, the 12 EC tower system is particularly suitable for construction sites where a very limited amount of space is predicted. The 12 EC tower system comes in two lifting capacities: the 12 EC 100 and the 12 EC 125.
The first eight cranes in the new EC-B series are the 125 EC-B 6, the 220 EC-B 10, the 220 EC-B 12, the 240 EC-B 10 Fibre, the 240 EC-B 12 Fibre, the 340 EC-B 12, the 340 EC-B 16 and the 370 EC-B 12 Fibre.
