LIEBHERR’s A 900 C – ZW Litronic hydraulic excavators are rail-road excavators. For rail operation, they require a special rail guide device to travel on rails like a train, but then work like normal hydraulic excavators with all their optional equipment and attachments.

With the rail guide device lifted, they travel like standard mobile excavators on roads and ways, fulfilling all the requirements of local traffic laws, and do their standard jobs with all their equipments and attachments.

The designs of all our rail-road excavators have been certified and approved by the German safetyatwork inspectorate for civil engineering (“Tiefbau-Berufsgenossenschaft”, TBG) and Deutsche Bahn AG (DB), Germany’s main railway operator.

This manual has been prepared to provide you with technical information on the design and construction of the various components which made up the LIEBHERR excavator.

It contains brief and precise descriptions, guidelines and drawings of adjustment procedures as well as hydraulic and electrical schematics, and graphically depicted diagrams and sectionals to help you with any repairs, which might become necessary on our hydraulic excavators.
