History
[edit]It was created in the USSR in the 1960s for the engineering troops of the Soviet Armed Forces, but found wide application in many civilian sectors. The machine is mounted on the basis of the T-155 light artillery tractor, created on the basis of the T-150K agricultural wheeled tractor of the Kharkiv Tractor Plant.[1] The working unit PZM-2 is a bar chain organ. In addition, there is auxiliary bulldozer equipment and a winch. In frozen soils, the machine ensures the excavation of trenches only.
In 2013, one PZM-2 earthmoving machine was modernized in Ukraine,[2] receiving a modernized hydraulic system.[3]
Technical specifications
[edit]The vehicle is powered by a 165 horsepower (123 kW) SZMD-62 turbocharged diesel engine. The transmission has six forward and two reverse gears, with an additional six slower gears for digging. To achieve sufficient traction, the vehicle was also equipped with a 5,000 kg hydromechanically driven winch, which was located at the front of the machine. The PZM-2 has a roller chain on which there are digging buckets, and it is driven mechanically by the main tractor engine. A sliding plate is attached to the front of the vehicle. This is used to prepare the site of the trench or, traditionally, for earthmoving and dozer and soil leveling tasks.
All the mentioned works are performed in any climatic conditions in the temperature range from −40 ºС to + 40 ºС.
