Underground Directional Boring Trenchless Machine Four Pump Hydraulic System
Key point:
1. With the use of four-pump hydraulic system (open constant-power system),DL80 crawler integrated hrizontal directional drilling machine has better working efficiency.
2. it has 47.3Kw engine .its forced air cooling system enables it to work reliably for long time.
3. Additionally ,its impact structure and sound climbing capacity can make transfer and transportion of the equipment more convenient ,High-speed operation system has multi-shift stepless speed regulation function,signficicantly increasing the operation efficiency.
