Liebherr is presenting the new A 922 Rail Litronic in exhaust emission stage V. Because it is a railroad machine, the A 922 Rail is suitable for use on railway tracks and for road construction and is fast thanks to the mobile undercarriage. A rail travel drive is mounted on both sides of the undercarriage. When entering the rails, the rail travel drive lifts the tyres to rail height. The inside wheels of the dual tyres ensure travel of the excavator on the tracks. With the A 922 Rail, Liebherr is offering the perfect overall package: the basic machine, the rail travel drive, the quick coupler system, attachments and all of the safety systems are developed by Liebherr and perfectly customised for the machine. Liebherr has been developing and producing railroad excavators for rail construction since 1967 and is global market leader in this segment as an OEM manufacturer.
