Rotary drilling rig is a kind of construction machinery, which is suitable for the construction of foundation engineering. Mainly suitable for the construction of sand, clay, silty soil and other soil layers, and has been widely used in the construction of grouting pile, continuous wall, foundation reinforcement and so on.
The rated power is generally 125~450kW, the power output torque is 120~400kN / m, the maximum pore diameter can reach 1.5~4m, the maximum hole depth is 60~90m, which can meet the requirements of various types of large foundation construction.
