EC-B cranes are an irreplaceable part of the Liebherr product portfolio. Flat-Top cranes have outstanding properties, relating to both their erection and transport, and their special design without tower head also means that multiple cranes can work closely together safely on constricted sites.
Nowadays, Flat-Top cranes are the standard crane on building sites around the world. We have taken the outstanding features of the existing EC-B series as a basis and improved them with a range of highlights to ensure that they remain the crane of choice for the future. The impressive design of the new top-slewing crane also convinced the top-class expert jury of the Red Dot Design Award.
The new EC-B cranes can of course be combined with the existing towers in our portfolio. The special feature of this is that they use the performance of the tower systems better than ever before. This means that even the largest Flat-Top crane, the 370 EC-B Fibre, can be used with the 21 HC 290 tower system without any restrictions – in other words you enjoy top economy with a conventional tower system which is already widely available on the market.
Even the standard versions of the cranes achieve long ranges. We can also deliver options to adjust the jib length flexibly to suit your site. A three-metre extension achieves the longest ranges in all classes. A 2.5 m intermediate section allows the standard increment of 5 m to be refined even further so that you can use your cranes on as many different sites as possible.
No hoist is too heavy for the new EC-B cranes. The Load-Plus function gives you up to 20% more lifting capacity at the touch of a button.
The EC-B cranes deliver even greater capacity if you use the fibre versions. The core feature of the cranes with the new fibre rope is the low weight of the rope and hook block, which directly affects the crane’s lifting capacity. The unique features of fibre cranes also include a longer service life and easier maintenance and handling.
The core of the crane, the slewing platform, was the particular focus for the revision of the EC-B series. Lightweight construction methods mean that the new models are up to one tonne lighter - depending on the crane type. Furthermore, both the cabin and the switch cabinet platforms are secured to the slewing platform with quick-release connections so that they can be installed and removed quickly. The reduction is particularly beneficial if only small mobile cranes are available.
The LiConnect quick-release connections make connecting the slewing platform to the jib and counter-jib even easier and safer. This means that the erection process can take place in difficult weather conditions and at a slight gradient – in other words at a positive or negative angle. This saves time in the erection preparation process.
The jibs for the new EC-B cranes have extremely small external dimensions. This means that three long jib sections can be stacked on the bed of a standard truck for transport. In other words, for example, the 370 EC-B Fibre can be transported using just four trucks. This reduces both CO2 emissions and transport costs.
One jib pin can weigh up to 30kg. That is quite a weight for a service technician to handle at great heights. So we have come up with the perfect solution. In the future the erection engineer can insert the pins safely using a handle and a centring tool. The flattened end of the pins, the centring tool, makes inserting the pins easier, particularly if the component being erected has not yet been properly aligned.
To help service technicians, the EC-B cranes have an additional support for the counter-jib guying. The height can be aligned precisely using a smooth running adjustable spindle. This makes erection easier.
Transporting the counter-jib with the pickaback system is a time-tested transport option for existing EC-B cranes. Loading and unloading in one hoist helps to speed up the erection process and transporting the complete counter-jib on one truck shows that large cranes are now as compact as small ones.
We are all familiar with tapping, swiping and pulling on a smartphone or tablet. The control system of our EC-B cranes is now just as simple and intuitive. A touchscreen, gesture control, clear displays, excellent menu structure and all the main information at a glance – extensive training and induction times are reduced as a result of the simple control interface of the TC-OS Tower Crane Operating System.
The adjustment of the operating-range limiting system is supported graphically by the TC-OS. The limiting shape is drawn and displayed in real time. The crane operator can adjust the map alignment as he wishes, similar to a vehicle navigation system. That means that either the crane or the environment moves in the display.
Modern construction is characterised by ever greater complexity in less space, coupled with time and cost pressure. The demands on construction machinery and its operators are growing, especially for tower cranes. The control system on the new EC-B cranes feature the familiar Litronic assistance systems to help crane operators with their work whilst also increasing handling capacity, reliability and safety.
The scaling process is one of the most important steps in a safe commissioning procedure for a crane. The newly developed scaling assistant provides the service technician with predefined masks and selected possible inputs for this purpose. The control system automatically adopts the correct load diagram and settings. At the same time a logic check of the settings is carried out in the background.
With a floor area of 2.35 m2 the LiCAB® has more space than any previous flat-top cabins. A well-designed, tidy interior design, the individually adjustable control stand and various other features make the cabin into a second home.
In addition to its size, one of the main features of a crane cabin is the quality of the view it provides. Even from the outside, it is obvious that the LiCAB® has been redeveloped from the feet up with particular attention being given to the view. That enables the crane operator to have a perfect view of the site at all times, enhancing the safety of personnel and the machine.
The LiCAB® is available in three different equipment versions. Even the Basic version includes a range of comfort features and ergonomic improvements. We can supply the perfect version for any climate zone, be it hot or cold. Our LiCAB® Air and the LiCAB® AirPlus feature a new air conditioning concept.
The crane operator’s workplace must provide adequate comfort to enable him to concentrate on his work for a full day. The control stand can be tilted, moved or the armrests can be adjusted ergonomically to suit the individual needs of every crane operator.
Publicity for your company at the most exposed point of the construction site – all made possible by the striking, unique look of the new EC-B cranes.
Design the crane to suit your wishes and ideas. We can deliver a range of versions to enable you to finish the crane in your corporate colours.
Up to 9 m² of advertising space is included for you in the crane’s design. We supply the complete package, including installation and lighting.
