Horizontal Directional Drilling Machine Chassis:
Integrally formed by whole big size rectangular thick steel (rather than welding),higher hardness than industry standard, suitable for big diameter and high-strength construction.
The coating uses car chassis electrophoretic coating technology, strong corrosion resistance.
Dual-speed motor as option, high speed for walking, low-speed for loading, stable and safe. Both wire control and wireless control as option.
Horizontal Directional Drilling Machine Power Unit (Rotating) :
Big brands: USA EATION./SAYI
Power unit is designed with high flowing system with 10mm, avoiding wrong operating, protecting rods screw, providing longer life span.
Dual speed rotating suitable for various different projects and processes ,max rotating speed upto 130m/min
Horizontal Directional Drilling Machine Main Beam (Push/Pull) ：
Integral forming by big thickness shape steel ( rather than thin wall steel pipe), the track is by 40mm thickness steel plate, capable for high strength construction.
Installed with USA Brand high-torque plunger motor, push-pull system pressure increased by 30%, faster and more agile, much better than cycloid motors and ordinary piston motors.
Three-stage push-pull function as option, maximum push-pull speed up to 34m/min
Horizontal Directional Drilling Machine Gripper：
The reamer and drill bit can be directly pulled into the retractor mechanism for loading and unloading; the equipment is equipped with roller seat, making sure the drill rod in the centre.
Each gripper sheet can be individually controlled to ensure centering is synchronized and holding is synchronized.
Clamp unit is designed with high flowing system with 10mm, avoiding wrong operating, protecting rods screw.
