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

The hydraulic system is the "power core" of second-hand rotary drilling RIGS. Excessively high pressure can easily lead to pipeline burst and component wear, while excessively low pressure will affect drilling efficiency and even cause equipment failure.
