The demand for ready-mixed concrete is growing rapidly across China, with consumption varying by city size. In small cities, annual usage is approximately 1 million cubic meters, while medium-sized cities use between 1 and 3 million. Large cities consume 3 to 5 million, and super-sized cities exceed 5 million. Transporting this material from mixing plants to construction sites is a crucial part of the process. Each concrete mixer truck can transport about 15,000 cubic meters annually, requiring dozens to hundreds of trucks per city, giving rise to a specialized transportation industry. According to recent data, domestic production of concrete machinery exceeded 50% of expected output last year, with continued growth anticipated. Concrete mixer trucks, bulk cement trucks, and pump trucks show strong market potential. China's annual production capacity for mixer trucks is around 6,000 units, with demand reaching nearly 7,000 in 2004 alone. By 2010, demand is expected to reach 12,000. With major infrastructure projects underway, pump truck sales have surged. Experts predict that annual demand for pump trucks will surpass 1,000 units in the next three to five years, reaching 2,000 by 2010. Currently, most Chinese concrete mixer trucks use 6-7 cubic meter capacity vehicles. These are categorized into three types: domestically produced chassis with imported components, imported chassis with some local assembly, and fully imported models. Domestic options are cost-effective but less reliable, while imported models offer higher reliability but come at a premium. The price difference between top-tier models is small, with imported Japanese Isuzu and Mitsubishi chassis remaining popular due to their performance and profitability. Bulk cement trucks, though less technologically complex, have a large number of manufacturers. Output has surpassed 500 units, and experts expect a significant increase in demand as regulations limit the use of bagged cement. Market demand for mixer trucks has grown at over 30% annually, with expectations of exceeding 5,000 units per year soon. By 2010, demand is projected to hit 12,000. Pump trucks, though fewer in number, carry high technical value. A large pumping height model costs between 3–4 million yuan, with profits once reaching 1 million. Now, prices have dropped slightly due to increased competition and localized parts, but profits remain above 500,000 yuan. Pump trucks come in various models, with booms ranging from 20 to 50 meters. While most components are imported, some domestic companies are beginning to localize parts, offering more affordable alternatives. However, challenges remain. The market is saturated with too many manufacturers, leading to low profit margins and intense competition. Many small companies produce only 180 units annually, which hinders long-term development. Additionally, financial issues such as delayed payments and poor fund management plague the industry. Experts warn that without innovation and intellectual property protection, China’s domestic brands may lose competitiveness and become dependent on foreign technology. Despite these issues, the future of the industry looks promising. As commercial concrete becomes more widespread, especially in urban areas, there is a huge opportunity for growth. Equipment will focus on energy efficiency, safety, and user-friendliness. With the Western Development Strategy, demand for practical and cost-effective machinery in underdeveloped regions is expected to rise significantly. Overall, the industry faces both challenges and opportunities, and success will depend on innovation, quality, and strategic development.

Compound Machine Series

Realized the processing of rough hobbing+edge extrusion and deburring+ fine hobbing of the medium and small module gears at one time, and completely solves the problem of flanging burr and bulge on the tooth surface. While significantly improving the machining accuracy of gears, it avoids the reduction of tool life or machining accuracy caused by flanging burr or bulge in the subsequent process after heat treatment.
