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.
Specifications
- Main engine power
The main engine is equipped with motor power:
Motor power: 90KW Y280M-4 Speed: 1450 R/min
The motor is connected with two American SauerDanfoss hydraulic pumps through a coupling, and a load sensing control system is adopted.The maximum rotary flow is 140L/min and the maximum push-pull flow is 85L/min
- Power head:
A high-speed hydraulic motor with a speed reduce is adopted for that rotation of the pow head,The motor is an axial piston variable motor manufactured by Rexroth in Germany or Sam in Italy, equipped with a 5-speed manual transmission and a reverse gear function.Five gears and ten speeds are steplessly adjustable.
