In the domestic rotary drilling rig market, XCMG and Sany are firmly in the first tier, forming a differentiated competitive pattern of "strong torque and efficiency". XCMG is deeply engaged in the field of heavy infrastructure, establishing the label of "torque king" with high torque and high stability; Sany focuses on intelligent and efficient construction, becoming a "efficiency pioneer" with fast-paced operations and intelligent technology. The core parameters and advantages of the two major brands each have their own focus, accurately matching the needs of different construction scenarios.
XCMG rotary drilling rig is positioned as heavy-duty and high-end, with core advantages concentrated in ultra high torque, deep pile construction, and structural stability. It is the preferred brand for national major engineering and complex geological projects.
In terms of core parameters, the flagship models of XCMG XR series perform outstandingly. The XR1200F has a maximum torque of 1200kN · m, a maximum drilling diameter of 4.6 meters, and a depth of 150 meters. Equipped with a 708kW high-power Cummins engine, it can easily handle the construction of ultra deep and ultra large diameter hard rock pile foundations. The mainstream model XR360F has a torque of 398kN · m, a drilling depth of 103 meters, a 345kW Volvo engine matched with a multi gear power head, and strong adaptability to soft and hard soil layers.
Technical advantages focus on hardcore performance and reliability. The box type mast is made of high-strength steel with strong deformation resistance. It is equipped with A-type support legs and thickened rotating platform, which ensures minimal overall shaking during high torque construction and full stability. The multi gear power head can flexibly adjust the speed and torque, and the load sensitive hydraulic system is energy-saving and efficient. The long-term high-intensity construction failure rate is lower than the industry average. Applicable scenarios cover heavy infrastructure such as high-speed railway bridges, cross sea bridges, and large reservoirs, especially adept at complex geological conditions such as hard rocks and pebble layers.
Sany rotary drilling rig focuses on intelligence, high efficiency, and flexible adaptation, deeply cultivating the housing construction, municipal, and small and medium-sized infrastructure markets with an "efficiency pioneer" attitude, and improving construction efficiency by 15% -20% compared to the industry average level.
The core parameters focus on efficient operation and flexible adaptation. The SR series has a torque coverage of 150-600kN · m, with the mainstream model SR360R having a torque of 380kN · m, a drilling diameter of 3.2 meters, a depth of 60 meters, a total weight of 128 tons, and outstanding maneuverability. As a star medium-sized machine, SR250 has a main hoist lifting force of 256kN and a maximum speed of 63m/min, suitable for small and medium-sized pile foundation projects within 50 meters.
The technological advantages are concentrated in intelligent control and efficient construction. Equipped with a self-developed intelligent electronic control system, it supports remote monitoring, fault warning, and automatic operation. The 3-millisecond high-definition touch screen is easy to operate and reduces labor costs. The full stroke pressurization system (up to 15 meters in length) is suitable for long casing construction, and the drill pipe visualization technology displays the position of the pressurization table in real time to avoid equipment damage. The strength of the sixth generation drill pipe has been increased by 25%, with strong impact resistance and outstanding construction efficiency in sand and gravel layers and moderately weathered rocks.
In terms of power system, XCMG prefers international high-end engines such as Cummins and Volvo, with power coverage of 345-708kW, sufficient torque reserve, low power attenuation under heavy load conditions, and suitable for long-term hard rock drilling. Sany uses Caterpillar, Isuzu and other engines with a power of 220-300kW, focusing on optimizing the power to weight ratio, with fast response speed and smooth composite movements, suitable for high-frequency and fast-paced construction.
Each hydraulic system has its own focus. XCMG adopts multi pump coordination and load sensitive control, with high pressure and large flow output, matched with high torque power head. When drilling in hard rock, the pressure is stable, the power output is linear, and the failure rate is low. Sany adopts the main winch rapid merging technology, with fast hydraulic response speed, high synergistic efficiency of composite actions (lifting, pressurization, rotation), fast pore forming speed, and obvious advantages in soft soil construction.
The difference in intelligent layout is significant. XCMG focuses on construction stability and safety, with standard features such as automatic mast adjustment, one click drilling, and bottom protection. The operation is simple and reliable, suitable for precise construction of heavy-duty projects. Sany focuses on full process intelligent control, integrating 5G remote control, AI drilling path optimization, and fault self diagnosis system, which can achieve unmanned operation, reduce labor costs, and adapt to large-scale and standardized construction.
Reliability and after-sales have their own advantages. XCMG's entire machine structure is thick and durable, with core components made of high-strength materials, designed for a long service life and strong long-term high-strength construction stability. The after-sales network covers the whole country, and the response time does not exceed 24 hours. Sany has strong adaptability to high-frequency working conditions, high universality of vulnerable parts, convenient maintenance, extensive overseas market layout, and a leading export volume in the industry. It is suitable for construction scenarios with multiple construction sites and frequent transitions.
XCMG rotary drilling rig is more suitable for large-scale infrastructure, complex geology, and ultra deep pile scenarios. For projects such as cross sea bridges, high-speed rail hubs, and offshore wind power, facing the demand for hard rock, ultra large diameter, and ultra deep pile foundations, XCMG's large torque machine can maximize its value and ensure construction stability and safety.
The Sany rotary drilling rig is suitable for building and municipal construction, small and medium-sized infrastructure, and soft soil formations. Projects such as urban residential buildings, commercial buildings, and municipal roads pursue construction efficiency and economy. Sany intelligent and efficient models can shorten construction periods, reduce costs, and enhance comprehensive benefits.
