• Newly developed and intuitive userinterface: Tower Crane Operating System (TC-OS) impresses with a streamlinedmenu structure.

• 12-inch multi-touch display ensuresexcellent readability, even in difficult lighting conditions.

• EC-B and EC-H series cranes will beequipped with the long-life display.

Liebherr is in the process of delivering itsfirst tower cranes featuring a newly developed display. The 12-inch displaywith multi-touch technology and intuitive operation now comes as standard inEC-B and EC-H series tower crane cabins. For crane operators and assemblyengineers, this fourth-generation Electronic Monitoring System (EMS) bringsmajor improvements in operability and especially in terms of crane scaling.

The long-life EMS-4 display with the new TowerCranes Operating System (TC-OS) user interface is the timely successor to the EMS-3.For its development, Liebherr enlisted the experienced support of the expertsat User Interface Design GmbH.

The focus for the development process was oneliminating distractions and displaying exactly the right elements required.The result is a streamlined menu structure with easily recognisable icons andsymbols. Navigation is simple, intuitive and satisfying. Exceptional usabilitymeans that training and familiarisation times are reduced.

Increasedoperational efficiency for top slewing cranes

Crane operators and assembly engineers havespecific menus, a wide range of languages and relevant units of measurement(metric and Anglo-American systems) at their disposal. The clear menu structureensures that they always have an overview, even during crane operations orcrane scaling in difficult conditions. This offers extra safety and a morecomfortable user experience.

Even in difficult lighting conditions, which areoften encountered in crane cabins, the anti-reflective and dirt-resistant touchscreenprovides optimal readability. There are different viewing modes available fordaytime and night time working. The display can also be tilted and rotated.

Allessential information on one display

Personalised settings that are relevant to the jobin question can be saved via crane operator profile and retrieved at the startof a shift. Display masks can be combined in various ways for this.

An external screen for the hook camera is nolonger necessary as the image can be integrated into the EMS-4. This means thatall available data is visible to the crane operator on one device, enablingthem to carry out lifts with even greater precision and safety.

The introduction of the new display alsoincreases operator comfort in terms of crane cabin settings. For instance, theair-conditioning system and windshield wipers can be conveniently controlledvia the multi-touch display. It is also possible to use the ergonomicallypositioned, easy-to-reach membrane keys for such purposes.
