2020 New design for DTH hydraulic crawler rock drilling rigs
|
Engine
The matching YUCHAI turbocharged water cooled engine can provide 100 or 125 horsepower powerful power, when drilling operation can meet the power demand of no more than 1500 r/mIn speed, and the engine emissions meet the current emission standards. 
|
|
Rotary head
Straight tooth gearbox with high load can adjust rotary speed according to rock hardness. Rotary head is matched with USA Eaton hydraulic rotary motor.The enhanced shock absorber is installed to reduce the impact reaction force of drilling hole and improve the service life of the gearbox. The dual rotary motor can be selected to adjust the speed and torque to ensure faster drilling under different working conditions of hard and soft rock. 
|
|
Feeding & Lifting
Adopt USA Eaton large torque motor, match 800 N.m brake propulsion and lifting force up to 20k.n, braking is reliable, single drill rod maximum lifting speed up to 4.3 seconds, can reduce the time for you to change the rod. 
|
|
Maintenance-free chassis
Equipped with imported high-torque traveling motor, it can pull air compressor at will, support wheel maintenance-free aluminum belt plate, there is a mud discharge groove, not easy to get stuck, track protection plate can prevent the chain rail from falling off, disassembling and disassembling operation pedal is suitable for remote walking operation |
|
Gravity axle frame
It adopts straight-through gravity axle with high bearing capacity, which enhances the firmness of the connection between the body and the track, and makes the chassis of the drilling rig durable and not easy to be deformed. When walking across the slope, the passing capacity can reach 20 degree and the longitudinal climbing can reach 35 degree. |
|
Travelling motor It is equipped with imported plunger travelling motor, with brake valve and mechanical brake, high braking sensitivity and strong traction drive, which ensures the bearing capacity of KHITAN-900 DTH hydraulic crawler drilling rig with 9 tons. |
|
Easy to operate The Ergonomic design of the centralized console operation to achieve the centralized control of multiple actuators, smooth oil flow, feel comfortable and smooth, and the installation of centralized pressure measuring device maintenance convenience, rain proof dust proof. |
|
Dust removal collector The high quality aluminum inside, guarantees the efficiency and service life of dust removal and effectively reduces the use cost of dry dust remover. |
|
Pulse controller can automatically control the injection time of filter element accurately and improve the dust absorption ability. |
|
Climbing ability 35 degree
The mine terrain is complex and changeful, whether the turning field is fast, whether the climbing slope is safe, is an important standard to test the quality of drilling rig.With nearly 9 years of field feedback, KHITAN-900 DTH hydraulic crawler drilling rig can climb up to 35 degrees easily, quickly and safely. |
DRILL PANGOLIN Air Compressor
|
DRILL PANGOLIN & LIUTECH teamed up to manufacture an air compressor matching KHITAN series hydraulic crawler drilling rig, reaching the drilling target of No Fastest Only Faster.
LIUTECH as a multinational compressor supplier ATLAS COPCO group, a wholly owned company in China manufacturing, is a company specializing in the production of screw air compressor and its post-processing equipment manufacturer, has been committed to provide users with the compressed air system solutions.
