Abstract: The scraper conveyor SR-70M used in the coal industry for its direct purpose has become a base, making changes in it allows to get a different functional purpose. Within the framework of this article it is shown how the replacement of the traditional pan line made of unified pans connected by the bar locks to the nondetachable pans allows the best use of the conveyor when performing cross-cutting. In order to eliminate the identified shortcomings, a new lightweight design of pans is proposed. Analysis of existing designs shows that nondetachable pans are suitable for these conditions, as in mobile face scraper conveyors. The new linear nondetachable pan has welded structure. The simple design allows to manufacture the designed pans in repair-mechanical shops of mines or at repair-mechanical factories. The design of the new nondetachable pan has been proposed. As a guide of the traction body they used a profile of the sidewall of the coal conveyor pan (TU 0951-071-00186223-2005). The connection between the pans is replaced by a bolted one. These changes in the basic design of SR-70M allowed us to create a lightweight scraper conveyor used in cross-cutting. Industrial tests confirmed the performance of both the conveyor itself, as well as the nondetachable pans. As a result of the mine tests of the experimental model of the lightweight scraper conveyor SR-70M the operability of the design of the new nondetachable pan and the conveyor as a whole is confirmed.
