The first drawback of this complex is that it decreases the reliability of the complex because of the numerous lever connection error, more acceptable to install Burlakov at the point of drilling, mining, according to the passport fastening.

The second drawback stems from the fact that it is possible to work in the mines with a maximum cross-sectional, which limits the scope of the complex.

The third disadvantage is the lack of location drifters during the construction of permanent attachment to the maximum height of excavation, moreover, that some operations are performed manually: supply of ampoules, washers, nuts, etc.

The fourth drawback is that there is not drilling holes on one line of the roof bar, fastening only on washers separately.

The technical result of the invention is to improve the reliability of the timberman, reducing errors during the construction of the permanent fixing, improving mobility and increasing applications in both the minimum and maximum cross-sections of the mine workings.

This technical result is achieved by the fact that in the complex, to the exclusion of the deposits and securing mining, spreader beam with a retractable telescopes, manipulators, with means for permanent attachment mounted on retractable telescopes spacer beams, the rotary shaft is made in the form of a telescopic lifting boom with lifting strut cylinders.

Spacer beam in the transport position, does not extend past the dimensions of the harvester and freely fits within the parameters of excavation at its disposal and moving.
