The new PMA-3 tamping-lining-leveling machine has successfully completed a full cycle of tests and is preparing for serial production. The project was implemented by the Kalugaputemash plant, part of the STM group.
The tests took place at the experimental railway ring in Shcherbinka, where the machine confirmed its declared operational characteristics. Specialists checked compliance with safety requirements, structural speed, the operation of electrical, hydraulic, and pneumatic systems, as well as the interaction of the control system with the working bodies.
After the tests were completed, specialists performed the final equipment setup at the production site. The next stage was the work of the acceptance committee, which resulted in the signing of the acceptance act. Now the developer has to obtain a certificate of conformity, after which the PMA-3 can go into serial production.
The PMA-3 was developed by STM specialists to perform a full range of work on leveling and lining railway tracks, compacting ballast, and stabilizing the track. The main feature of the new machine is its ability to operate continuously. This solution significantly reduces the duration of technological windows during railway infrastructure repairs and increases the productivity of track work.
According to the developers' estimates, one PMA-3 can perform the volume of work that previously required up to three previous-generation machines. This makes the new equipment one of the most productive solutions in its class.
