FIELD: transport.SUBSTANCE: track machine comprises running gear with the main frame fitted at two bogies, first a two-axle bogie and second one a single axle bogie. Both bogies are provided with spring unloading hydraulic devices. Single-axle bogie is fixed and is rigidly mounted at said main frame. Main frame from support accommodates the cabin provided with current collector intended for control and measurement of contact system. Crane-manipulator is mounted at the other support. Main frame mid part has mounting pad with lifting mechanism. All actuators of the track machine are mounted at said main frame and located under its top level. These bogies exploit hydraulic spring suspensions and spring unloading devices.EFFECT: uniform load distribution on rails, higher stability of track machine.5 dwg |
