For mineral vein structures, rock mechanical properties, and foundation evaluation in city construction, it is important to have a full, unbroken core for these purposes. In contrast to conventional manual coring, which is slow, physically taxing, and depth limited, large drilling rigs commonly have access issues when faced with confined sites such as karst caves and difficult terrain. In response to the industry problem, Sinovo core drilling rigs have won the recognition of construction teams worldwide for their convenience, versatility, feature high efficiency and accurate control, export to a lot of countries.
Based on the working principle of diamond coring rotating drilling, Sinovo core drill rigs employ a power head to push the drill rod and core barrel assembly at high speed rotation with water or mud as the circulation medium for cooling to realize annular cutting in abrasive materials like rock and concrete. The bicapsular core barrel configuration, known as the dual-tube core barrel, guarantees that the core sample fitting into the inner tube of the dual tube core barrel is effectively shielded against mechanical disturbances as well as disintegration can by flushing fluid, if carried out, and that the quality of the recovered cores is consequently kept along with the original bedding structure and physical-mechanical properties. With higher core recovery rates and better representation of the core samples, Sinovo core drilling rigs also allow for accurate detection of underground geological anomalies, such as faults, fracture zones and karst cavities—which is critical information for subsequent design and construction. Therefore, core drilling rig are popular applied in energy and mineral exploration(for finding the mineral vein locations and estimating the quality of the mineral resource), transportation, hydraulic engineering and urban construction (to analyze the load-bearing stratum to rationally design the construction scheme), scientific research (to research the inside structure of geological hazard bodies such as landslides and seismic fault zones) Sinovo core drilling rigs are recognized as reliable partners for achieving high-efficiency coring across diverse and challenging engineering environments.
SINOVO offers both mechanical and hydraulic core drilling rigs:
Sinovo Mechanical Core Drilling Rig (XY Series)
Capable of drilling diameters from 75mm to 500mm and depths from 100m to 1,800m. The Sinovo skid-mounted spindle-type coring rig XY-1A weighs as little as 420kg, making it portable and manually transportable—ideal for mountainous areas with limited access and shallow coring operations. It offers both diesel and electric motor power options for flexible on-site selection. Equipped with multiple fixed speed ranges for intuitive operation, its maximum pulling capacity reaches 138.5kN, effectively addressing stuck pipe and buried drill incidents. With low maintenance costs, high parts interchangeability, and a simple mechanical gearbox structure, this rig demonstrates strong adaptability to site conditions, exceptional cost-effectiveness, and rapid return on investment.
Sinovo Hydraulic Core Drilling Rig (SD Series)
Achieving coring depths from 400m to 2,500m with core diameters compatible with BQ, NQ, HQ, and PQ sizes, this series is tailored for deep-hole sampling with higher penetration rates and superior sample integrity. Compared to mechanical models, hydraulic rigs deliver significantly greater power—the SD-2000 reaches up to 194kW—effortlessly handling a variety of complex formations. The infinitely variable speed control allows real-time optimization of rotational speed based on formation hardness and bit wear, enhancing drilling efficiency and extending bit service life. Additionally, the SD-1000 features a maximum feed stroke of 4,200mm, substantially increasing the distance per trip and reducing rod-handling cycles. This not only minimizes mechanical vibration damage to core samples but also cuts auxiliary time for more efficient coring results. During operation, hydraulic core drilling rigs offer higher automation and enhanced safety, with automatic monitoring and pressure relief upon detecting abnormal resistance, effectively prolonging equipment life and reducing wear and replacement costs. The centralized control panel eliminates the need for frequent manual tripping operations, significantly lowering operator fatigue. Moreover, compared to mechanical rigs, Sinovo hydraulic coring rigs accommodate larger diameters—PQ size suitable for hydrogeological and engineering requirements. The efficient coring performance accelerates project progress, generating higher returns for your business.
