Trenchless Horizontal directional Drilling machine underground pipe laying under DL660S
INTRODUCES
1, With the use of closed loop of tha main rotation hydraulic system ,DL660S crawler integrated horizontal directional drilling machine has better working efficiency and it has 194Kw engine..its forced air cooling system enables it to work reliably for long time.
2, 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.
3, The rotation hydraulic system is of closed loop and the high-strength drill pipe holder is sent on the outer side of the crossarm featuring simplicity,reliability,easy assembly&disassembly of drill pipe and high efficiency.
4, The top-end PALL filter can ensure cleanness of the hydrulic system and long service life of the equipment .
