GD450-L/LS HDD Machine

1. Rotation, push-pull, clamping and walking use German Rexroth automatic variable system, load-sensitive control; its hydraulic system is 15%-20% more efficient than traditional hydraulic systems, and can save energy by 15%-20%.
2. It adopts Cummins special engine for construction machinery with strong power.
3. The power head can be increased, and the maximum push-pull force is 900kN, which guarantees the safety of construction during large pipe diameter construction.
4. The girder adopts a four-bar linkage beam structure, which greatly increases the range of incident angle, and at the same time ensures that the crawler of the drilling rig does not leave the ground at large angles, which improves safety performance.
5. Wire-controlled walking system to ensure the safety of personnel and equipment during walking.
6. The loading and unloading of the drill rod adopts a mechanical arm mechanism with adjustable flip angle, which is convenient and quick to load and unload the drill rod, which greatly reduces the labor intensity of the construction personnel and improves the work efficiency.
7. It is suitable for φ89×4500mm and φ102×4500mm drill pipes, and the machine body occupies a moderate area, taking into account the requirements of efficient construction and narrow site construction.
8. The main components are selected from international first-class hydraulic component manufacturers, which greatly improves the reliability and safety of product performance.
9. The circuit design is scientific and reasonable, with low failure rate and easy maintenance.
10. Using rack and pinion push-pull, high efficiency, stable work, convenient repair and maintenance.
11. The caterpillar adopts steel caterpillar and rubber gasket, which can bear high load and can meet the requirements of walking on various roads.
