High Strength Yellow Engineering Drilling Rig 450 Ton Rotation
Hydraulic System
ADVANTAGES
1, With the use of closed loop of tha main rotation hydraulic
system ,DL3000cralwer integrated horizontal directional drilling
machine has better working efficiency,and it has advanced automatic
control system enabling more rational power distribution of the
engine.its forced air cooling system enables it to work reliably
for long time.
2, 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 holder is of whole-travel type and its front and rear clamps
are separable for various adverse conditions.
4, The high-strength drill pipe holder is sent on the middle of the
crossarm,featuring simplicity ,reliability,easy
assembly&disassembly of drill pipe and high efficiency with the
use of 5t hoist .
5, The key parameters of the engine,main hydraulic system pressure
and filter etc.can be input automatic controller for effective
equipment safety protection.The machine is exported to India
