I mine 690 mid-section of the delivery of waste rock and by-product of the original 8S shuttle car and 0.75 m3 car. As the tunneling system in full swing, also added 2m3 side dump truck, for which. Must transform the fixed 2m3 unloading track. 1 Reinforced the bottom of the curved track after the transformation of the track is able to move the overall translation. To meet the activities of 5320mm long curved rail unloading the strength and stiffness requirements?
