Specification

T Machinery a.s. produces shearers for bi-directional and unidirectional mining of deposits of coal and some other minerals in the form of seams. Shearers are primarily designed for coal mining, but also for mining of salt, oil-bearing shale and other minerals. The shearers are manufactured in accordance with the requirements of Directive 2014/34/EU (ATEX) and in accordance with the equivalent directives of the Russian Federation and Ukraine.

The shearers, according to our own, 50 years proven design, are produced in several series, according to the thickness mined. Each shearer is designed to meet specific customer requirements. MB series shearers resist the toughest mining and geological conditions, with an ever-efficient mining performance, which has proven and continues to prove in the mines in Russia and Ukraine.

T Machinery a.s ensures the highest quality and durability of these highly variable mining machines by production in our own production plant in the Czech Republic.

Where other engineering companies have abandoned the development of shearers intended for small thicknesses, T Machinery company has developed a new line of MB machines for the toughest conditions. New portal version of shearers can achieve mining outputs of up to three thousand tons per day in a seam thickness of only 0.8-1 m. This means that T Machinery changes the economically uninteresting deposits to mineable and profitable deposits.

The shearers are equipped with powerful drives and picking organs, powered by world-class electric motors. The power supply and control of the feed rate of the shearer, depending on the strength and the momentary conditions of the mined seam, are solved by the frequency converter with the transformer, also developed and manufactured by T Machinery. Upon request of the customer, the shearers can be fitted with elements to increase of abrasion resistance.
