| Abstract:LGZ series full hydraulic multi functional pile rigs are featured of three patented technologies, i.e. axial sliding kelly bar, large torque hollow rotary power head and double drum synchronous hoist. They have the technical advantages of construction safety, multiple functions, stable and efficient transmission. This paper introduces the performance parameters and technical characteristics of this series of pile rigs, and their application in construction of five types of piles, including screw pile, screw displacement pile, cement soil mixing pile, CFA pile and large diameter CFA pile. It has been proved that LGZ series full hydraulic multifunctional pile rigs can meet the construction requirements of various pile foundation construction methods and can be extended to application of other construction methods. |
