With the A 922 Rail two-way excavator, Liebherr is presenting a special machine for deployment on road or rail. Liebherr presented the new A 922 Rail Litronic two-way excavator for the first time at the Bauma trade fair in 2013. The transition to the new series is currently taking place in production and one of the first machines will be presented at the NordBau. Like the earlier A 900 C ZW machine, the A 922 Rail can operate on roads or railways with its service weight of either 19.9 or 22.2 tonnes.

The A 922 Rail is available with optional four-point supports and can, depending on the intended work area, be supplied with a rail-track undercarriage for broad-gauge rail systems or a friction drive wheel for narrow-gauge systems. Optionally available: a 3.40 m long luffing boom or a boom that can be repositioned laterally, in this case 3.60 m long. There are also dipper arms 1.85 m, 2.05 m, 2.25 m or 2.65 m long that have been specially designed for work below overhead wires.
