underground pipe laying HDD machine DL660 for Hydraulic Drilling Rig
1, With the use of closed loop of the main rotation hydraulic system ,DL660*23 cralwer integrated horizontal directional drilling machine has better working efficiency ,
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 ratation 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 with the use of 2t hoist.
4, The top-end PALL filter can ensure cleanness of the hydraulic system and long service life of the equipment.Optional force adding module is available for additional 33t force.
