 Push the performance characteristics of the hydraulic slip: thrust, light weight; bending strength, goes on smoothly; sealed and reliable, and easy maintenance. Use: Face or general machine gun mining face conveyor goes. 
 First, the purposes and characteristics 
 YT4-6A, YT4-8A Hydraulic push the running device, is to meet the coal mine blast mining, mining face the needs of the design manual shift slide apparatus. This SGW40T, SGW80T several models such as flexible conveyor and other small supporting the use of conveyor to accommodate different forms of coal mines to meet the greater requirements of users, can reduce accidents, civilization production and lower costs achieved remarkable results in all aspects. This type of push-running device can be used as a small hydraulic machines, widely used in equipment maintenance, handling accidents and some need the top, pushing the occasion. 
 Second, the technical characteristics: rated thrust; 39.2kN, Rated recovery Rally: 9.3kN, over speed (the handle back and forth once): 17mm, handle lift; 7mm. Handle pressure: 10mm. The vertical angle when the maximum stroke: the pump-side low: 60 °, the pump-side high: 14 °, by force multiplier: ≈ 90 times the dimension (piston rod when the whole collection): Stroke 600m 855 × 135 × 210 , stroke 800mm 1055 × 135 × 210, using the weight: travel 600mm 32.5kg, stroke 800mm 38kg initial fuel injection stroke 600mm 3.3kg, stroke 800mm 3.86kg, oil grade: 20 # machine oil
