HFDD-400 Full Hydraulic Horizontal Directional Drilling Rig
- Max. Push capacity: 4000kN
- Max. Pull capacity:4000kN
- Engine Power:2x275kW
- Rotary Torque:110000N.m
Features
- 1Adopting first-class hydraulic products in the world and the hydraulic circuit in closed for push-pull and rotation, and open for auxiliary circuit loading sensing system working together, and with electric-hydraulic praportional control in high efficiency.
- 2Adopting double power system to meet different working condition, the power unit can work with two engines or one flexibly to save the energy and to reduce the consumption; if one hydraulic system or engine goes to disorder, the other one can work normally(working capacity keeping without change, but operation speed reduced).
- 3Adopting electrical and manual control of operation valve group, imported from USA, the main Sauer control valve is very reliable,
- 4Pointers and electronic devices are adopted together for data showing of the rig, rig pressure, torque, rotation speed and push-pull capacities are clear at a glance.
- 5 Adopting two-low- speed and large torque motor made by Poclain Hydraulics Industrie SAS, France for the rotation of drill head; set with 2 gear stepless speed adjustment function, floating of spindle is helpful for protection of rod thread.
- 6 Adopting six motors with reducer driving for drill head feeding/pull and adopting rack and pinion transmission structure, the rig is in high stability and efficiency.
- 7 Installed with operation cabin equipped with air conditioner, the rig is easy to operate in a comfortable working environment.
- 8Shackles can be adjusted for the space of making jaws and breaking jaws; breaker can be centered automatically, breaking accurately, stably and reliably and gripper can move on the mast full stroke.
