The A 922 Rail can be equipped with a rail guide for regular-width, and wide tracks or friction wheel rail guide for narrow tracks, depending on operating requirements. It sets the standard in its class for fuel efficiency and reliability.
Powerful Liebherr drive with easy maintenance
The A 922 Rail Litronic is powered by the 110 kW / 150 HP Liebherr diesel engine D 834 that complies with exhaust emissions stage IIIB. The exhaust gas treatment is effected by a diesel oxidation catalyst, while a particulate filter module can also be used if required.
The diesel engine drives a double hydraulic pump with a rated output of 2 x 215 litres per minute. Each pump can be controlled separately, for troublefree operation of tool attachments with an intensive power requirement, such as mulchers, trench cutting machines or hydraulic pile drivers. While one pump supplies power to the tool attachment, the other permits the railroader’s travel and working movements to be supplied separately. The A 922 Rail also impresses with its high lift capacities.
Liebherr HVI hydraulic oil is used as standard on the A 922 Rail, and is capable of an operating life of more than 6,000 hours. Instead of fixed oil-change intervals, these are determined by the results of an oil analysis carried out every thousand hours of operation or once a year. To prolong the lifetime of the hydraulic oil, and as a reliable service indicator, for the return filter a magnetic rod is installed in the hydraulic oil tank as a standard item, and can be easily removed and cleaned when necessary.
The large engine cover on the A 922 Rail opens to expose the entire right-hand side of the machine, providing fast, convenient access to all servicing points. Day-to-day maintenance can be carried out from ground level; reducing service time and providing a safer workspace. To clean the generously sized radiator, the powerful fan can simply be swung out forwards.
