Product Description
Key Features
Achieve Precision & Zero Settlement with Simultaneous Drilling and Pipe Jacking
Horizontal directional spiral drilling rig can achieve synchronous drilling and pipe jacking, with high construction accuracy and no settlement in the construction area.
Robust Frame, Powerful Drilling, Precise Guidance: Core Structure of the HDD Rig
The host is frame type, and the power head and feeding mechanism are installed on the rack guide rail. The power head adopts an integral enclosed gearbox with high torque; The feeding mechanism adopts hydraulic cylinder propulsion and retraction, which is simple and reliable; Drilling tools are divided into directional drill rods and spiral drill rods; The guiding instrument is LED laser guided, with high accuracy and fast feedback speed.
