Working Principle of the YG Rotary Drilling Rig Machine:
This hydraulic rotary drilling rig operates through a combination of powerful engine drive and a precision hydraulic control system. The 88kW diesel engine provides the core power for the whole equipment, driving the gear pump to deliver hydraulic oil to the system at a working pressure of 20-25 Mpa, which powers the rotary mechanism, lifting system, and walking chassis. During operation, the rotary drive head drives the drill pipe and drill bit to rotate at a constant speed, applying continuous torque to break and cut the soil or rock layer, while the hydraulic system controls the feeding pressure and drilling speed to ensure stable and accurate drilling. The 180-degree rotating mechanism allows the drilling arm to cover a wide working range without frequent repositioning of the whole machine, greatly improving construction efficiency. The equipment can complete borehole drilling of up to 13 meters in depth and 600-1600mm in diameter in a single operation, meeting the requirements of most medium-scale foundation piling projects.
Application of Rotary Rig Machine:
1. Building Foundation Engineering: Pile foundation construction for residential, commercial, and industrial buildings, providing stable structural support for high-rise and low-rise constructions.
2. Municipal Engineering Construction: Borehole drilling for urban infrastructure projects such as bridges, overpasses, underground pipe galleries, and municipal square foundation works.
3. Transportation Infrastructure: Foundation piling for highway, railway, and bridge projects, including slope stabilization, bridge pier foundation, and roadbed reinforcement works.
4. Water Conservancy Engineering: Drilling works for reservoir embankment reinforcement, river bank stabilization, and water conservancy facility foundation construction.
5. Landscaping and Geotechnical Improvement: Borehole drilling for slope greening, foundation reinforcement, and ground improvement projects in complex terrain.
6 Features of YG Rotary Drilling Rig Machine :
1. Tuned Heavy-duty Power System with Stable Continuous Output
This rotary rig machine is fitted with an 88kW 4108 diesel engine, specially calibrated for engineering construction. It delivers consistent, non-declining power for both full-load drilling and high-speed chassis travel, with no torque drop even during 8 hours of continuous heavy-duty work, and fully adapts to off-grid field construction sites.
2. High-precision Responsive Hydraulic System with Professional Matching
This hydraulic rotary drilling rig uses an engineering-grade CBJT2080 gear pump, with a rated working pressure of 20-25 MPa and 80ml/r displacement. Precisely matched with the power unit, it delivers accurate linear control of drill pipe speed, torque, and feeding pressure, flexibly adapts to various formations to avoid drill sticking and borehole deviation, and enables precise control of the 180-degree rotary mechanism to cut idle time and boost efficiency.
3. Targeted Drilling Performance for Medium-scale Project Requirements
With a rated maximum drilling depth of 13m and an adjustable drilling diameter of 600-1600mm, this equipment is perfectly aligned with the needs of medium-scale pile foundation projects. It fully covers standard pile specifications for civil buildings, municipal works, water conservancy, and transportation infrastructure, and is compatible with multiple drilling tools to handle both support and load-bearing piles without extra on-site equipment matching.
4.180-degree Full-coverage Rotary Mechanism for Efficient Continuous Operation
This equipment features a 180-degree full-rotation drilling arm, matched with a stable chassis with a 3150mm wheelbase, 1400mm front, and 1060mm rear track gauge. Fixed in a single position, it covers a wide drilling area without frequent repositioning, and can complete continuous drilling of multiple pile positions in one setup in narrow municipal sites or slope works, cutting position adjustment time by over 30% per shift and greatly improving construction efficiency.
5. Highly Mobile Vehicle Chassis for Flexible Cross-site Transport
This rotary drilling rig is equipped with an integrated vehicle chassis with a rated maximum travel speed of 50km/h. It enables fast transfer between construction sites via urban and national highways without additional flatbed trailers, cutting transport costs compared to tracked drilling rigs of the same specification. With an overall dimension of 7900×2260×3100mm, 8000kg curb weight, and 2.26m body width, it easily passes through width-restricted urban roads and narrow rural roads.
6. Compact Heavy-duty Structure for Confined Space Adaptation
The whole machine adopts an integrated welded heavy-duty frame, with 8000kg curb weight and a stable 3150mm wheelbase. During drilling, it effectively offsets the reverse torque of the drill pipe, eliminating body shaking and overturning risks, and ensuring borehole verticality and construction safety. While guaranteeing heavy-load structural strength, its optimized 7900×2260×3100mm body is more compact than large rotary drilling rigs of the same specification. It can flexibly access narrow construction sites such as residential areas and old urban zones, solving the pain point that large equipment cannot enter limited working spaces.
FAQ About The Rotary Drilling Rig Machine
A: In conventional clay and sandy soil formations, this rotary drilling rig machine completes a standard 13m-deep, 800mm-diameter pile hole in 30-45 minutes on average. The time varies slightly based on formation hardness, drilling tool matching, and operator proficiency, fully meeting the schedule needs of most medium-scale pile foundation projects.
A: Yes. This hydraulic rotary drilling rig has strong process adaptability. Its hydraulic system supports stepless adjustment of rotation speed and torque, and can be matched with different drilling tools to complete CFG pile construction, micro pile drilling, slope anchor bolt drilling, and other common processes, realizing multi-purpose use of one machine and reducing project equipment investment.
A: For composite soft-hard interbedded strata, this rotary rig machine has a targeted control scheme. Its high-precision hydraulic system can fine-tune drilling torque, speed, and feeding pressure in real time according to formation changes to avoid hole collapse and deviation. The 8000kg heavy-duty stable chassis offsets drilling vibration, ensures pile hole verticality, and prevents common quality problems.
A: Only construction-matched drill pipes and drill bits are the core necessary items, with only a small loader needed for on-site drilling slag cleaning. The equipment has a built-in integrated drill pipe lifting system and an independent diesel power unit that needs no external power supply. It can operate independently in the field with only a diesel supply, greatly reducing on-site support thresholds.
