Liebherr is presenting the new A 922 Rail Litronic at the Conexpo Con/Agg 2020 trade show.
  • Operating weight 45,000 - 51,600 lb (20. 4 - 23. 4 t)
  • Can be operated either on road or rail
  • Decades of experience in developing and producing railroad excavators 
  • The new machine is available in both the Final Tier 4 and Stage IIIA (compliant) exhaust emissions standards
  • 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 tires to rail height
  • The inside wheels of the dual tires ensure travel of the excavator on the tracks 
  • The new 120 kW / 161 HP engine ensures that the A 922 Rail achieves even higher working speeds with the usual fluid equipment movements
  • The innovative hydraulic concept of the A 922 Rail consists of a Liebherr variable displacement double pump with independent control circuits
  • High-performance, hydraulic attachments can be operated independently of the working and travel movements of the Liebherr railroad excavator
  • The delivery rate of the proven Liebherr variable displacement double pump was increased to 2 x 220 l/min for even better performance
  • The heavy ballast was also redesigned to yield the best bearing load values with improved weight distribution and a more compact rear dimension of 6.6 ft (2,000 mm)
  • The service-orientated machine design of the A 922 Rail guarantees short maintenance times and minimizes the associated maintenance costs thanks to the time savings
  • All maintenance points are easily accessible from the ground
  • Air, oil and fuel filters, the main battery switch, the central lubrication point for the undercarriage and the pilot valves for the hydraulic system are much easier to access
  • The spacious double cab featuring standard roll over protective structure (ROPS) and a modern interior design offers the best conditions for comfortable, focused and productive work
  • Entrance lighting is provided to make accessing the cab easier
  • The usual generous use of glass and standard rear and side cameras provide an exceptional view of the working area and swing range
  • The touch-screen color display used for display and operation purposes, as well as the other control elements on the console and comfortable driver's seat are all perfectly matched to one another to form the perfect unit
  • The safety technologies include load torque, height and sway limitation and the virtual wall
  • The A 922 Rail is available with various undercarriage versions with different track widths and rail wheels, which make it possible to use it on tracks worldwide
  • An independent variable displacement pump for the rail travel drive provides the best traction and safe propulsion at all times
  • Standard integrated brakes in the rail wheel shorten the braking distance in both the lowered and elevated position and enhance safety 
  • The railroad excavator can be fitted with an optional, fully hydraulic quick coupling system developed by Liebherr
  • The hydraulic quick coupler system combined with an automatic, hydraulic coupling system enable a quick and secure change of mechanical and hydraulic attachments from the cab
  • Increased productivity by 30% on average
