Leveling, Tamping and Aligning Machine
for straight track VPR-02M
| Machine VPR-02M is designed for leveling, tamping and aligning of railway track in manual and semi-automatic modes during maintenance, repair and construction of railways. Machine is designed for operation on main track with rails up to R65 (inclusive) on wood and concrete sleepers with bolts and skid fastenings and any type of ballast on gradients not exceeding 20%. The machine is equipped by microprocessor for controlling leveling operations.|
Machine is self-propelled unit consisting of operation module and articulated trailed semi-flatcar resting on track by self-aligning wheelset.
The track is tamped by two tamping units which operate independently and able to move in lateral direction. The control system of tamping units permits to set necessary values of tampers penetration in ballast depending upon the ballast condition and types of rails and sleepers.
The track is lifted and shifted by lifting-and-aligning device. It grips the rail head, lifts the track panel section and shifts it without resting on ballast. The ballast is compacted by two compactors at the end-faces of sleepers. The compactors are unbalanced vibrators actuated by hydraulic motors.
