1.1 Equipment Purposes HGY5120DYH is used to deal with the road damages such as local cracks, ruts, pits as well as for the repair work of country road, squares, community road and the temporary pedestrian paving work .It can enhance the skid resistance and waterproof of the road surface, to improve road flatness road surface and traveling comfort with the result that the effect “renewal” is achieved. 1.2 Main technical parameters  Product Model: HGY5120DYH  Engine Power: 140 kw  Aggregate bin volume: 5m3  Emulsion tank volume: 1.2m3  Water tank volume: 1.2m3  Cement tank volume: 0.5m3  Output capacity of mixer: ≤1200kg/min  Dimensions: 7660×2400×2770 (L x W x H) 1.3 Characteristics of Equipment  It can meet the requirement of pits patching (cold patching) construction technology and achieve spraying with viscous oil, cold-patch materials mixing functions.  The feeding system has a quantitative ratio and can achieve continuous feeding.  The auxiliary equipments are equipped with hydraulic power interfaces to meet the dynamic needs of different devices.  It’s also equipped with high-pressure cleaning, lighting and other auxiliary function to facilitate construction.  Double axles in mixer stir the mixtures powerfully and completely to make sure no mixing dead-angle and good slurry effect. It can achieve 110°rotation synchronization construction and the discharge location of the mixing tank can be adjusted in construction thus is more efficient.  It has automatic heating function which ensures the quality of construction and extends the construction season. It can calculate the size of the pits and metering the discharging process which is highly automated.
