As the economy continues to grow, the demand for hydraulic boarding bridges in China has been steadily increasing. More and more manufacturers are entering this market, eager to capture a share of the expanding industry. Lifting machinery plays a crucial role in modern logistics sites, serving as the starting and ending point of the entire logistics chain. These hydraulic lifting platforms are designed for efficient and safe loading and unloading of goods, making them essential in industrial and warehouse operations. However, due to varying heights between transport vehicles and loading docks, there is often a gap or height difference that makes direct access difficult. This is where the hydraulic boarding bridge comes into play, providing a stable and secure connection that allows electric flat cars to move safely and quickly between the vehicle and the dock.

With the growing interest in the domestic market, many companies have entered the industry, resulting in a mix of strengths among manufacturers. Over time, those with strong technical capabilities and business strategies have emerged as leaders, building up their scale and reputation through continuous innovation and quality improvement.

As competition intensifies, domestic manufacturers are increasingly focusing on product diversification and technological advancement. Many have invested heavily in R&D to develop new products tailored to local needs. The performance of hydraulic boarding bridges, fixed bridges, and mobile bridges has improved significantly, leading to a more diverse range of options available in the market. In response to fierce competition, some manufacturers have expanded by acquiring smaller firms and exploring international markets. While they are making progress, there is still a significant gap compared to global industry leaders. (http://)
