The powered support КД90ТС consists of four-props sections with the ceiling, equipped with controllable from front hydraulic props visor, four-chain linking system of the basis with the barrier; the basis – rigid-linked catamaran-type; extension ceiling and barrier boards – double-sided.
The powered support КД90ТС was first made in 2016, was demonstrated at the exhibition «Coal of Russia and Mining» and is used now in the «Sherlowskaya-Naklonnaya mine» in the Rostov region.
