Tongchuan Zhaoshi River Bridge

SR360 rotary drilling rig * 8983 times with the same type of well-known products at home and abroad, in the West (An) Tong (Sichuan) Expressway Zhaoshi River Bridge project, composed of mudstone and sandstone, rock uniaxial compressive strength of 50 ~ 80MPa No. 7 cushion cap is recognized as extremely difficult to play a cushion cap, Sany SR360 rotary drilling rig successfully laid 20 pile holes with a diameter of 2m and a depth of 70m. The Sany SR360 rotary drilling rig worth more than 8 million yuan and the internationally renowned brand products worth more than 17 million yuan competed in the same construction competition, which verified that the SR360 rotary drilling rig "created in China" broke the monopoly of international brands in the field of large-diameter and deep foundation piling equipment in China, and was an effective witness to the independent innovation of Chinese products, creating a leap for China's piling machinery to catch up with the world. SR360 rotary drilling rig has a number of patented technologies, unique luffing mechanism design, so that the mast can be tilted back to the horizontal position, but also forward to the horizontal position, reduce the transportation height of the whole machine, improve the flexibility of the drilling rig's maneuverability; Using winch pressurization, *8981 large pressure up to 280 kN, ** pressure stroke *8981 up to 10m, the power head adopts 3 sets of motors, reducer, providing 350kN.m * strong output torque, to ensure that the construction is completed under different geological conditions; The upper part of the mast adopts a truss structure, which has strong bending and compression resistance to ensure the stability of the whole machine and the rigidity of the mast. The hydraulic system distributes the flow to the actuator of the system working device on demand, so as to achieve the best and most beautiful match under the load of each working condition.
