From Domestic to Imported: Differences in Advantages and Applicable Scenarios of XCMG, Sany, Liebherr, and soi Rotary Drilling Rigs

        In the field of basic engineering construction, the performance of rotary drilling rigs directly determines the efficiency and quality of pile foundation engineering. XCMG and Sany are the leaders of the domestic camp, while Liebherr and Tuli represent the technological height of imported equipment. With different technological focuses and product positioning, the four have demonstrated unique value in various construction scenarios.

XCMG Rotary drilling rigs

        XCMG rotary drilling rig is known for its stability, reliability, and wide adaptability. Its independently developed core power system is efficiently matched with a fully hydraulic system. For example, the XR360F model is equipped with a Volvo National IV engine and a large displacement hydraulic device, with a torque of 360kN · m, which can easily handle complex formations such as hard soil and moderately weathered rock. The intelligent upgrade significantly reduces the operating threshold, and the one click vertical adjustment function can control the error within 0.5 °. The one-time acceptance rate of drilling can reach 100%, greatly improving the construction accuracy. In terms of service guarantee, XCMG relies on a well-established domestic service network to achieve rapid response to faults and convenient maintenance. The standard centralized lubrication system and online fault diagnosis function further reduce equipment maintenance costs. These characteristics make XCMG rotary drilling rig the preferred choice for medium and large-scale pile foundation projects such as housing construction, bridges, and municipal construction, especially suitable for scenarios that require frequent transitions such as urban pipeline networks and highway pile foundations. Its design with pole transportation not exceeding 3.8 meters can flexibly cope with narrow construction environments in urban areas.

SANY Rotary drilling rigs

        Sany rotary drilling rig focuses on "high efficiency, energy saving and intelligent innovation". Through cooperation with high-quality suppliers worldwide, its engine not only meets strict emission regulations, but also achieves precise power distribution through power optimization control technology, reducing fuel consumption while ensuring power output. The C10 series telescopic widened chassis, combined with roller type large-diameter slewing bearings, provides a solid and stable foundation for deep hole construction. The sixth generation drill pipe adopts upgraded materials and reinforced ring structure, with a strength increase of 25%, which performs outstandingly in highly weathered rock layers. Intelligent configuration is Sany's core competitiveness. The drill pipe visualization function can display the pressure table position in real time to avoid damage. The 10 inch high-definition touch screen and centralized automatic lubrication system simplify the operation process and extend the equipment life. From the construction of long casing in beach gravel layers to deep pile foundation operations, Sany rotary drilling rig, with a pile diameter coverage range of 1100-2500mm and a pile depth capacity of 20-100m, is widely adapted to the diverse needs of civil engineering, especially in large-scale projects that require high efficiency and energy conservation. Its advantages are obvious.

LIEBHERR Rotary drilling rigs

        As a global engineering machinery giant, Liebherr's core advantage in rotary drilling rigs lies in "multifunctional integration and technological depth". Relying on advanced manufacturing technology, the equipment not only has strong durability, but also can switch between various drilling methods such as rotary drilling, long spiral drilling, and full displacement tool drilling. A single device can meet the needs of multiple working conditions. The intelligent control system is its technological highlight. Through precise power allocation and optimized operation logic, it not only reduces the labor intensity of operators, but also improves job safety. Even in continuous construction under complex geological conditions, it can maintain stable efficiency. As a globally recognized brand, Liebherr's service network covers a wide range, and its after-sales service has received high praise from users. These characteristics make it highly competitive in large-scale cross-border engineering and multi geological composite scenarios, exhibiting balanced performance in both rapid drilling of soil layers and precise drilling of rock layers.

Soilmsc Rotary drilling rigs

        The earth powered rotary drilling rig is based in the market with "strong performance and high-precision control", and its design fully integrates the construction experience of typical global projects. From the correction of the Leaning Tower of Pisa to the foundation construction of Dubai Palm Island, many iconic projects have confirmed its ability to adapt to extreme environments. The electromechanical integration system installed on the equipment achieves multiple precise controls, including electronic control that matches the engine and load, and manual and automatic switching of mast verticality, allowing SR-30 and other models to maintain extremely high drilling accuracy during rock drilling operations. Tuli has professional factories and multiple maintenance service points in China, with technical support provided by technicians trained by Italian manufacturers, ensuring the professionalism and timeliness of services. With the stability advantage brought by all original imported equipment, the earth powered rotary drilling rig is more suitable for special projects with strict precision requirements, complex rock construction, and large-scale landmark projects. Especially in scenarios that require long-term high-intensity operations, its durability advantage is more prominent.

        The difference between the four major brands from domestic to imported is essentially the differentiation of technological paths and market positioning. XCMG and Sany have become the mainstream choices in the domestic infrastructure market due to their high cost-effectiveness, scene adaptability, and comprehensive services; Liebherr and Solilmsc, with their technological accumulation and high-end performance, occupy a place in complex working conditions and high-end projects. When selecting equipment, it is necessary to comprehensively consider the project scale, geological conditions, budget costs, and service requirements in order to achieve the optimal balance between construction efficiency and project quality.
