66 Ton Hdd Directional Drilling / Trenchless Boring Machine Ratation Hydraulic System
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, it has 194Kw engine .its forced air cooling system enables it to work reliably for a long time.
3,High-speed operation system has multi-shift stepless speed regulation function,signficicantly increasing the operation efficiency.
4,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.
5,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.
