Liebherr’s New Rail-Road Excavator for Track Construction on Display at InnoTrans
Liebherr is presenting the A 924 Rail Litronic at the InnoTrans 2022 trade fair in Berlin. The A 924 Rail Litronic has an operating weight of 21,800 kg to 25,000 kg and is equipped with a 120 kW / 163 hp strong and robust engine.
The machine can be used both on rail and on road. To complement the versatile machine, Liebherr will be showing numerous attachments as well as a quick coupling system for a wide range of applications.
In combination with the optimally coordinated hydraulic system, the machine reach constantly high work speeds with the usual fluid working movements.
For exhaust emission stage V Liebherr uses a newly developed SCRT system comprising a SCR catalytic converter and a standard particulate filter. The innovative hydraulic concept consists of a Liebherr variable displacement double pump with independent control circuits. High-performance, hydraulic attachments can thus be operated independently of the working and travel movements of the machines.
The rail travel drive is mounted on either side of the undercarriage. During unloading the rail guide is lowered in axle pairs until the inner wheels of the dual tyres are at the track wheel and ensure a frictional connection of the travel drive.
The service-orientated layout of the machine guarantees short maintenance periods and minimises the associated costs thanks to the time savings. All maintenance points are easily accessed from the ground.
