Make sure to check out the new generation excavators from Liebherr on display at AusRAIL PLUS.
The new 120 kW/163 PS engine of the A 922 Rail ensures it 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 thus be operated independently of the working and travel movements of the Liebherr railroad excavator.
The heavy ballast was also redesigned to yield the best bearing load values with improved weight distribution and a more compact rear dimension of 2000 mm.
The R 914 Rail provides the same maximum precision and power on rails as other Liebherr models with its powerful diesel engine and extraordinary sensitivity.
The short tail crawler excavator R 914, with a rear slewing radius of just 1550 mm, is designed to work on the tracks of constricted construction sites or where access may be difficult.
This all-round excavator is powered by a four-cylinder in-line engine which accelerates the hydrostatic rail travel drive to speeds of up to 25 km/h.
- Service-orientated design
The service-orientated machine designs of the A 922 Rail and R 914 Rail Litronic guarantee short maintenance times and minimise the associated maintenance costs, thanks to the time savings. All maintenance points are easily accessible.
- Comfortable double cab
The A 922 Rail’s 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, and 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 colour 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.
- Safety systems direct from manufacturer
Occupational safety is extremely important in track construction. Liebherr therefore offers its own safety systems which are perfectly tailored to the machine requirements.
- Liebherr attachments and quick coupler system
The A 922 and R 914 Rail boast many different areas of application, thanks to the broad range of Liebherr attachments.
To improve productivity even further, the railroad excavators can be fitted with an optional, fully hydraulic quick coupling system developed by Liebherr. This can increase productivity by 30 per cent on average.
CASE STUDY
One of many businesses which is more than happy with the performance of the excavators is Victorian and NSW-based Rail Maintenance Services (RMS), which provides wet/dry plant and equipment hire to rail transport operators, and civil and commercial construction companies across Australia.
Since its inception 51 years ago, RMS has acquired the depth of resources to undertake and deliver projects in live operational environments, with defined delivery deadlines and specialised needs, and a comprehensive fully owned fleet of specialised plant and equipment, skilled operators, field technicians and professional services.
RMS business manager George De Domenico said there were currently 12 Liebherr machines in operation.
“Their lifting capacity exceeds all other models in their category, and we’ve enjoyed the strong relationship with Liebherr Australia that started more than 35 years ago,” he said.
De Domenico said the company valued the main features of safety ability in lifting, traveling, and braking.
“Liebherr’s constant focus on compliance and safety ensured the acquisition of the next fleet of A 922 Rail and R 914 Rail Excavators, which are designed for our Australian conditions and comply with AS7502-2016 and RSU700,” he said.
“They are constructed for safety and fit for purpose and delivered by a world class company with exceptional services, which allows RMS peace of mind to achieve its core values and business plans.”
“The many safety features include a double redundant version height limiter, and ease of setting up tool recognition.
“Other advantages include ease of operational functions, and impressive performance in clearing train stops and pulling lengths of rail.
“The transmission modes on the tracked machines also exceed any other OEM performance.”
De Domenico was also impressed with Liebherr’s 24-hour back-up service reliability, fuel economy, long life of the undercarriage and the overall superior life span of the Liebherr machines.
He said operators found the machines easy to operate with the number of functions available, with the machines able to be tailored to operators’ needs.
“Also there’s just one overall warranty, not made up of different suppliers,” he said. “Even though the machines are complex, when you need assistance, one call to Liebherr covers the complete machine. You don’t need to worry about trying to work out who to call.
“The reliability, reduced operation expenses, backup support, backed by the confidence of an international OEM of Liebherr’s standing, is comforting.”
