Hydraulic 80t Crawler Drilling Rig For Underground Pipe Laying , Air Cooling System
ADVANTAGES
1, With the use of closed loop of the main rotation hydraulic system ,DL800A cralwer integrated horizontal directional drilling machine has better working efficiency ,and it has 264Kw engine .its forced air cooling system enables it to work reliably for a 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, Push and pull gear rack system, push and pull motor is low speed large torque motor, high starting efficiency
4, The steel plate caterpillar track has good strength and convenient installation and maintenance
5, 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.
