DGY220 Track Measuring Machine
DGY220 is hydraulic-mechanical driven, equipped with imported Caterpillar C9 power unit, and applicable to track measuring incl. catenary of standard track gauge metro line.
The machine is applicable to high-speed measurement of track geometry and rail wear, and able to realize high-accuracy, real-time and dynamic inspection of rail state. For the measured data, self-contained analysis software can be used for state analysis of different levels, so as to develop the line maintenance plan; the CATENARY detection car is applicable to comprehensive inspection of rigid/flexible suspending CATENARY parameters for electrified railway of urban rail transit, and used to provide guidance basis for dynamic rechecking after maintenance of tested line, comprehensive quality assessment and fault diagnosis.
