Bridge reversed loader with the face-scraper conveyor machine synchronous over his head, face Shearer guarantee for coal mining, and fully mechanized coal face of high yield and high efficiency operations. Scraper conveyor is a reprint of a special structure of the scraper conveyor, powertrain and drive and scraper conveyor similar to a ramp of its fuselage and a section of the arch bridge structure and belt conveyors in the tail Paragraph above lap. In the back-alley in the coal face when the machine goes to reprint its arch bridge and all of the aircraft ended the lap belt conveyor stack of position limits, a retractable belt conveyor shortened ride Next length of the belt conveyor for the development of the shift to home-unloading nose reproduced below, can be reproduced with the face of the advance goes forward. Reproduced large-scale machine is fully coal face with the equipment supporting the use of the Gate transmission, reproduced equipment, to complete the face conveyor sent to the coal transportation, transit facilities to follow up on the conveyor belt of tasks and to provide the appropriate means of connection. ZY2300 belt with the design requirements for supporting the tail since the shift to achieve in the 2.3 metres of the overall mobile rather than demolished shift belt machine. ZY2300 belt and the tail of the shift can be more easily cope with belt-regulation, enhance the belt-and-reproduced with the coordination. This reprint of MG300/700-WD and supporting the use of conveyor, capacity up to 1,000 tons / hour, technologically advanced, reliable, large-scale comprehensive mining equipment supporting the excellent models.
