The PST-12 special tractor trailer was developed in conjunction with the PMU-15 lift for the first time (there are no direct equivalents) specifically for the mechanization of construction, reconstruction, maintenance, and emergency response work on power lines.

When combined with the PMU-15 lift developed by DORMASHEXPO, it enables the full range of operations involving loading/unloading, transportation, installation, and assembly/disassembly of power line supports, optimizing the equipment fleet and reducing production costs for energy supply organizations.

The trailer has been put into production by "DORMASHEXPO" LLC.

The Joint Institute of Mechanical Engineering completed R&D project "Developing and mastering the production of a multifunctional machine for transporting, installing, and assembling transmission line supports". The results were used to create a special trailer.
