Crawler Excavators Liebherr tunnel excavators are special machines which can be used in all conventional types of tunnelling applications: After tunnel drilling machines have been used to create cross-tunnels, 1when explosives are being used for secondary profiling, and, of course, for direct excavator tunnelling. Particular features of these machines are their economic operation, high performance, and reliability.

To prevent damage from falling rocks, all the hoses in exposed locations on the equipment fittings are additionally secured by protection plates. The bucket cylinder is also attached in a lower position, and a cover fitted to both the lifting rams protects the hoses running between them. Comfort Characteristic of the special cab on the Liebherr tunnel excavator are the ergonomic design and high standard of operating comfort and convenience. The windows on the right and at the rear are fitted with polycarbonate panes, resistant to scratches and impacts, and feature extremely good visibility properties. As an option, the cab is also available with polycarbonate window panes all round.

As well as this, the front window can be fitted with a grille to provide protection against falling rock fragments. As another option, the Liebherr crawler loader can be fitted with a camera to monitor the area behind the machine. By way of a display in the cab, this provides a better view to the rear, and therefore provides greater safety for personnel who are within the working area of the machine. Comfort The Liebherr single-lever operating system for travel and working hydraulics allows the crawler loader to be con- trolled with fingertip sensitivity. Functions integrated in the two joysticks make process sequences even easier. Depending on the application demands, travel speed forwards and backwards can be programmed from 0 – 10 km/h. In addition, the float position, automatic bucket positioner, and automatic lift kickout deactivation can be easily pre-selected in the operational controls.
