Full Hydraulic Pressure Rotary Mode Drilling Rigs for Pile Foundation
Adapts to various stratum,the first choice for construction.
The machine is circumgyration drilling machine that the rotary drives drilling tool to bore by ratation, adopts full hydraulic pressure drive, constant power loop, wheel cylinder startup, oil sylinder disappearing and bumper, electrohyaulic combined control, steel wheel traveling and disassembly transport. The machine can adopt positive and nagative circulation and other deep drilling technique, adapt to various stratum. It is preferred equipment for foundation constrution of river’s bridge and dock, and also adapts to large diameter borehole construchtion such as sewage well. It takes great efforts in many bridges foundation construction of Changjiang River.
The machine wins the first prize of Scientific and Technical Advance in Henan Province and Zhengzhou City, the second prize of Scientific and Technical Advance of Construction Ministry and National New Product Prize in 1996 through the authentication of ministry grade, and obtions national parent. The main technical indexes is in leading position in domestic same species.
