The head of the machine was 30 feet 6 inches (9.30 m) long and 7 feet 3 inches (2.21 m) wide and 8 feet 7 inches (2.62 m) high and weighted about 30 tons. The head had a plough blade for cutting the top part of the trench to a depth of about 2 feet 6 inches (0.76 m), raising the excavated soil and pushing it to the sides of the trench.
A micro trencher is a "small rockwheel" specially designed for work in urban areas. It is fitted with a cutting wheel that cuts a microtrench with smaller dimensions than can be achieved with conventional trench digging equipment. Microtrench widths range from about 30 to 130 mm (1.2 to 5.1 in) with a depth of 500 mm (20 in) or less.

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 ...
A trench of the Änäkäinen fortification in Lieksa, Finland. A well-developed trench had to be at least 2.5 m (8 ft) deep to allow men to walk upright and still be protected. There were three standard ways to dig a trench: entrenching, sapping, and tunneling. Entrenching, where a man would stand on the surface and dig downwards, was most ...
[1] The most commonly known screw press of this design is said to have been invented by famous Greek mathematician Archimedes and is known as the screw conveyor. The screw conveyor consists of a shaft, which is surrounded by a spiral steel plate, similar in design and appearance to a corkscrew. This design is used in a multitude of screw presses.
