Horizontal Directional Drilling Machine GH26/GH26A
Performance Characteristics
1. Equipped with a Cummins engine, it offers strong power, stable performance, low fuelconsumption and low noise, making it ideal for urban construction.
2. The power head is directly driven by a high-torque cycloidal motor, offering high torque, stable performance, and two-speed stepless speed regulation.
3. The power head push and pull mechanisms utilize a cycloidal motor and integrated push-pull reducer, offering two selectable push and pull speed settings, making it agile and far ahead of its competitors.
4. The power head push-pull and rotation hydraulic system utilizes advanced series-parallel control technology and world-class hydraulic components, along with an independent cooling system, ensuring efficient, energy-efficient, and reliable operation.
5. A first-class hydraulic travel drive system ensures simple and convenient operation, enabling quick and easy loading and unloading, as well as site transfers.
6. The ergonomically designed, wide operating platform with a high-end seat that can be moved forward and backward provides a wide viewing area and comfortable, convenient operation.
7. The simple circuit design minimizes malfunctions and facilitates maintenance.
8. The GH26A is a space-limitation model specially designed according to customer’s requirements for construction at narrow sites but requires long distance and big diameter. It equips with φ60×2000mm drill rod. The machine is compact, it can be transported by a small truck, which is flexible and convenient, but the power and torque as well as the push-pull force is big, it is suitable to work at narrow sites for long distance.
