Specification

Powered roof supports ensure the mined area, safety of workers at the face and efficient and safe cave control. Mechanically powered supports produced by T Machinery a.s. are designed to withstand high pressures from the overburden and, at the same time, to safely perform the movement of wall conveyor at high stability.

Hydraulic stands and cylinders are produced directly in Ratíškovice. Production supervision allows the customer to provide a warranty for the operation of sections up to 50 000 service cycles. Fitting the stands in the sections of mechanically powered supports by impact valves extend their use to deposits with the danger of mountain shakes.

T Machinery a.s. produces the supports in the ranges for low to medium thickness, but also for the extraction of steep seams or for the extraction of thick seams by the method of discharging the seam bridge from over the ceiling. T Machinery a.s., as one of the few companies, produces shield supports to provide space for lignite mining.
