R55 Split-Type DTH Drilling Rig
The R55 mining drilling rig is a compact, efficient, and reliable drilling solution developed for demanding open-pit operations. Its optimized structural design combines a compact layout with a professional industrial appearance, delivering stable performance, flexible mobility, and convenient operation under challenging job-site conditions.
As a split-type drilling rig, the R55 crawler hydraulic drilling rig works with an external air compressor, allowing users to select a suitable compressed-air system according to the required hole diameter, drilling depth, rock hardness, and operating conditions. This flexible configuration helps improve equipment utilization while making transportation, installation, and on-site relocation more convenient.
Engineered for productivity and operational reliability, the R55 borehole drilling rig provides consistent feed and rotation performance for efficient rock penetration. Its user-friendly control layout enables operators to manage drilling operations accurately, while the robust structural design supports continuous work in dusty, uneven, and demanding environments.
The rig also emphasizes energy efficiency, operational safety, environmental responsibility, and simplified maintenance. Key components are arranged for easier inspection and servicing, helping reduce routine maintenance time and minimize unnecessary downtime. Its compact footprint makes it particularly suitable for job sites with restricted working space or frequent relocation requirements.
1. Adopts 4wheel and 1belt system for construction machinery, with reliable performance and low failure rate.
Adopts plunger type traveling motor, with strong climbing capacity and stable rig movement.
The control pedal can effectively improve the operator's safety during rig relocation.
2. The multiway valve is reasonably arranged, bringing convenient and quick maintenance and pressure adjustment.
The LCD display can accurately monitor the operation status of the threestage diesel engine, automatically switch operation modes according to actual working conditions, and has selfdiagnosis and alarm functions.
3. Yuchai threestage diesel engine, with strong power, reliable and stable operation.
4. 12filter element dust collector, with reasonable installation layout, strong negative pressure and good dust removal effect.
Rearmounted radiator, and the diesel engine adopts suction fan, bringing excellent cooling effect for the whole machine.
5. The rotary head is driven by dual hydraulic motors, with compact structure, convenient maintenance and large torque.
The sliding block is made of polymer wearresistant material, with strong resistance, convenient maintenance and stable operation.
6. 120L diesel tank ensures 8 hours of continuous drilling, reducing auxiliary operation time.
7. The traveling acceleration switching valve enables two traveling speeds of the drill rig, bringing convenient and quick relocation and site transfer.
8. The largebore leveling cylinder improves the structural strength of the whole machine, with stable and reliable vehicle body floating.
