As a "powerful tool for deep holes" in foundation construction, the reliability of rotary drilling rigs is directly related to project progress and cost control. Many construction teams neglect maintenance details, leading to frequent equipment failures and a service life reduction of more than 30%. Mastering refined maintenance skills is the core key to extending the equipment's service life. Read More

Today, as infrastructure construction and the "dual carbon" goals are deeply integrated, rotary drilling rigs, as the core equipment for pile foundation construction, are undergoing a crucial transformation from "scale expansion" to "quality upgrading". The green transformation and intellige Read More

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 eq Read More

In rotary drilling rig operations, rotation speed and torque settings are not fixed but must be dynamically adjusted based on geological conditions. Use high speed, low torque for soft soil; medium-low speed, medium-high torque for sandy gravel layers; and low speed, high torque for rock layers. The core principle is: Torque determines if it can drill, while rotation speed determines how fast it drills. The two must be perfectly coordinated for efficient and safe construction. Read More

In 2025, the global mobile crane market is restructuring. China, as the core engine, has a market scale of 85 billion yuan, while the global scale will exceed 22 billion US dollars, with the Asia-Pacific region growing at 6%-8%. On the demand side, the new energy sector drives a 35% growth in demand for equipment above 200 tons, and the penetration rate of new energy models exceeds 25%; the annual replacement demand is 32,000 units, and the online leasing rate will reach 60%. In competition, XCMG, Sany and Zoomlion hold a combined 68% market share, with leading enterprises strengthening advantages through green intelligence, globalization and full-life cycle services. The industry will develop towards "high-end, intelligent and green" in the future, with new energy penetration reaching 40% by 2030. To gain a foothold in the 75% concentration integration by 2030, enterprises must address raw material and R&D pressures and deepen technology and services. Read More
