Product Description

GP730 down the hole/DTH drill with closed cabin and automatic carousel system
Dragon GP730 automatic crawler DTH drill is a split-type hydraulic DTH drill. Using electronic fuel injection engine, hydraulic pump's power device, equipped with hydraulic automatic storage rod, exchange rod, 
unloading rod and the positioning device, luxurious cab etc. Comfortable and safe operating environment, greatly reduces the labor intensity and saves labor.
 Compared with the all-in-one type, operation and maintenance difficulty are greatly reduced, at the same time, failure rate is very low.



★ Engine     
 Using national standar III phase green
 high performance electronic control diesel
 engine, strong power, fuel efficient and low 
trouble.

★ Cab dashboard  


 Working parameters, notices, alarm function of 
drilling rig are integrated on the dashboard, which    
is convenient for the operator to observe. 
Real-time display of drilling angle, convenient 
for the operator to arrange the accurate holes.


★ Control console    
 The originally imported operating valves posses more reliable performance.
Centralized control console provides convenient operational control of drilling rig..  
Fast propulsive and lifting operation reduce auxiliary time and enhance working efficiency.
The propulsive force can be adjusted and controlled according to the drilling needs.


 ★ Chassis      
The floating frame, floating around 10°.
Using high and low double speed walking, transfer quickly between each site. 
                                     

★ Have multiple doors for maintenance easily   


★ Automatic rod discharge system  


With store function and automatic 
 discharge function.  Only the single 
handle bar can realize the function of 
 rod connecting, rod collection,
manipulator opening&closing and drill rod \  rod exchange in the store system.
                                                  
The rod discharge method is 
up&down clamping, this is convenient 
for loosen the rod joint to improve 
working efficiency.



★ Turn-around machine  



Double cycloid motor rotary device 
has big rotary torque, not easy to be 
stuck, meanwhile, the rotation speed 
can be adjusted according to different 
rock conditions.

★ Dust removal system  

Efficient hydraulic dust removal system with sliding dust-catch cover. Dust suppression is very efficient and stable. 
Effectively extend the working life of the machine and guarantee the operator's safety, environmentally friendly.
