With a long length (comparable to an eight-story building), the auger has a rather modest width - only 300 mm. The unit was made of steel. Due to its impressive length, it was assembled from several abutting parts. Production began with the cutting of "petals" - future blades from a sheet of metal using a plasma cutting machine. They turned out to be flat. Then they were welded together in a spiral, which was pulled out with a winch. Then the finished spirals were put on the rod.
The final operation is the control assembly of individual parts into one large screw. The assembled product took up almost an entire passage in the workshop. At this stage, the conformity of the product to the drawings, the correctness of assembly and the dimension were evaluated. The auger entered the PPM as a constructor.
