Hydraulic mining YT4-8A monomer push the running device, manually push the slide, hydraulic shift slide 
 Hydraulic push the slide, manually push the slide 
 The invention relates to mine the chute mobile device is a hydraulic push slide. Opposite sides of the structure for the front and rear of the cylinder outer wall were fixed with a former hydraulic valves and hydraulic valve, two valves between the cylinder block outer wall equipped with a positioning axis; cylinder by positioning axis located in the bracket on the vertical long holes; the bottom of the bezel, fitted with a fixed base plate, base plate near the piston rod end of the upward tilt; the top of the bezel, fitted with a fixed choke top seat, choking the top groove structure of the seat of the Ministry of backward tilt, and an angle of 20 ° -24 ° angle. The new design is reasonable, the hydraulic injection liquid gun injection fluid and the cylinder separation, easy to push the slide to move the cylinder at both ends adjustable; piston rod can be connected to the block of coal board normal contacts, extended equipment life. 
 YT4-6A, YT4-8A single hydraulic push slide, is designed to meet the needs of the coal mine blasting mining, mining face and the manual shift slide apparatus. Slip devices compared with other shift, adaptability, mobility and effortless operation, high efficiency, easy maintenance, safe and reliable than the concentrated oil hydraulic jacks shift slip can save a lot of investment economically viable. Several models with SGW40T, SGW80T flexible scraper conveyor, and other small scraper conveyor supporting the use of, to adapt to the different forms of coal mines, the greater to meet the requirements of users, can reduce accidents, civilization all aspects of production, lower costs achieved remarkable results. The same time, this type of push the slide can be used as a hydraulic machine, widely used in equipment maintenance, dealing with accidents and need top, push the occasion.
