Detailed description
The rated torque of the power head is 450kN · m, the maximum drilling depth of the six section frictional resistance drill pipe is 114m, and the maximum drilling diameter is 3m. It can handle 60MPa limestone hard rock, and the core extraction efficiency of hard rock is high; The speed of the power head is 7-25r/min, and it can be used for construction with both large and small apertures. The main winch has a lifting force of 52t, a rope speed of 70m/min, a maximum pressure of 40t, and sufficient power reserve for deep and large hole working conditions. Equipped with a 399kW Cummins engine, a Rexroth hydraulic system, optimized power matching, powerful heavy-duty operation, and good fuel consumption control.
Supporting independent lowering and lifting of the entire casing, backfilling soil and loose sand layers can effectively prevent collapse holes without the need for additional casing drilling machines, reducing supporting costs. Customized reinforced cooling system, high-speed cooling fan, suitable for high temperature and sandstorm overseas working conditions, capable of sustainable long-term continuous operation in high temperature environments in the Middle East and Southeast Asia. The whole machine has strong structural rigidity and excellent control of drilling verticality, suitable for deep pile foundation projects of bridges, high-speed railways, and super high-rise buildings
12 inch touch screen display, integrated with multiple intelligent functions: power head cruise control, stepless pressure adjustment, automatic soil throwing, oil dispersion automatic blowback, drilling tool bottom protection, reducing operating threshold and minimizing human error. Construction data can be recorded for easy review of working conditions and equipment management.
