What is Horizontal Directional Drilling?
The use of HDD was developed to install utility pipes and cables beneath or around a variety of surface obstacles including roads, rivers and railways. The technology was conceived in the 1970's combining techniques used by road boring and oil and gas directional drilling. HDD's are relatively compact and have a small footprint that allows the equipment to be set up in relatively tight spaces such as the boulevard of a roadway.
JL-60/85 Horizontal Directional Driller is a new underground piping construction machinery which is based on the advanced theory of “Trenchless Technology”. With fully hydraulic and power-drive technology, it achieves drilling, rotating, back-broaching, back-towing, and travelling. It is widely used for pipeline construction and maintenance for water supply, coal gas, electric power, telecommunication, natural gas, and petroleum in railways, roads, buildings, rivers, and other construction-limited areas, such as cultural protection areas, downtown areas, crops and vegetation conservation areas.
| Engine system Cummins engine: It can meet complicated jobsites construction demand. The engine also has high reliability and low energy consumption. |
| Mud pump Adopt ‘Tongfang’ mud pump which has 4 flow rates and 4 level pressures. So it can meet different diameter holes drill and pullback. The hydraulic motor drives the system, offering high pressure and stable performance. |
| Travel system Use the same system as excavator system’s support wheel, guide wheel, track idler, driving ring and spring. Rubber crawler or steel crawler with rubber palte has no damage to the road. Huge torque motor ensures strong grade ability. |
| Push and pull device Adopt motor and chain structure, rack and pinion structure, offering stable move, huge push force, convenient maintenance and reliability. |
| Clamping device The open-loop clamping structure is adopted, making the operation intuitive, convenient and reliable. |
| Power head Adopt ‘Tilorms’ large torque cycloid motors, power takeoff is much stronger. The two-speed rotation is controlled in the electro-hydraulic way and it is easy to operate. |
