Scraper conveyors manufactured by T Machinery a.s. company are an integral part of mining complexes. A substantial part of the production consists of scraper conveyors designed for travel of shearer and for extraction of disintegrated coal. These conveyors excel in their durability and flexibility. Drive stations can be equipped with up to four, water-cooled, motors to achieve the highest mining power. Conveyor motors are certified with ATEX.
The conveyors are manufactured from E-profiles of standard quality, as well as according to special design of T Machinery a.s. The abrasion resistance is increased by special laser hardening, which is carried out on the inner surfaces of the E profile. Leading of traction chains may be extreme or central. The conveyor track is composed of welded troughs. Insertion into the trough track with inspection windows allows for inspection and maintenance over the entire conveyor length without time losses. The trough connection is flexible with a permissible load of 2 500 kN.
