JK730 Surface Drilling Rig with Automatic Rod Changer
With a power unit composed of diesel engines and hydraulic oil pumps, the automatic crawler-mounted drilling rig is efficient and energy-saving. A hydraulic motor facilitates drilling, feeding, lifting, walking and hydraulic cylinder positioning. The luxurious cabin provides a safe and comfortable operation environment that reduces labor intensity and labor costs. Without an integrated air compressor, the rig can be connected to air compressors as needed. This integrated drilling rig features its convenient operation and maintenance as well as low downtime rate.
Applications
The drilling rig is mainly used for blasthole drilling, well drilling, piling and micro-piling, foundation drilling and environmental survey hole drilling.
Advantages
- During operation, compressed air is utilized only by the DTH hammer, which reduces air compressor's output by 30% to 50% compared to pneumatic drill rigs and lowers energy consumption (fuel oil or electricity) by 40% to 50%.
- The rig is equipped with an automatic device that can store, change and connect drilling rods.
- With a hole locating device, the rig increases the precision of drilling holes.

Main Components
- Cabin
- The enclosed cabin is FOPS-certified.
- A large safety window offers a wide view which enables operators to better control the rig.
- With a ground clearance of more than 400 mm, it can be applied in rough terrains without colliding with the ground.
- Air intake system
- Three-stage air intake system ensures intake of clean air and reduces filtering costs and failure rate of engines.
- Rotation unit
- Double cycloid motors deliver a high torque output and reduce the possibility of jamming.
- Rotation rate can be flexibly adjusted based on different formations.
- The seals deliver reliable performance and have long service life.
- Dust collecting system
- The hydraulic dust collector with a sliding cover delivers stable and efficient performance.
- Control system
- The dashboard clearly displays the operational parameters for convenient monitoring and control.
- A hydraulic pilot control system enables precise control of the hydraulic system.
- The lever can be operated with one hand to control the drilling actions, such as feeding and rotation.
- It supports automated setting of drilling parameters, which is user-friendly and saves time.
- Dual hydraulic system supports smooth and steady traveling.
- Leveling jacks
- Maintenance-free leveling jacks are designed with a high-strength structure. With widened tracks, the rig has robust climbing capability.
- The leveling jacks are designed to angle to 10 degrees left and right. They support 2-speed shift.
