In July 2025, Huangshan Zhongguantai completed the delivery of hydraulic drainage trailers to customers in Shijiazhuang. Through standardized on-site acceptance, precise technical explanations and immediate practical guidance, the equipment was ensured to quickly adapt to the local flood prevention needs, providing crucial equipment support for the prevention of urban flooding and emergency drainage of road water accumulation in Shijiazhuang.

At the delivery site, the company's team worked together with the customers in Shijiazhuang to conduct a comprehensive final inspection of the entire process: Firstly, they handed over the factory inspection report of the hydraulic drainage trailer, the special manual for the hydraulic system, the list of spare parts, and all other technical documents to ensure clear traceability and compliance of the equipment; subsequently, they verified the integrity of the equipment's appearance, the sealing of the hydraulic pipelines, and conducted key tests on the response of the hydraulic system upon startup - during the on-site demonstration, the equipment went from being powered on to entering the pumping and drainage state in just 8 minutes, with a pumping and drainage efficiency of 1,000 cubic meters per hour. This can quickly respond to common flood scenarios such as water accumulation on the main roads and backflow in underground passages during the rainy season, and the deployment efficiency is 40% higher than that of traditional drainage equipment.

Regarding the equipment compatibility issue that the customers in Shijiazhuang were concerned about, the technical team, in combination with the local flood prevention characteristics, conducted a live simulation of the "drainage of road after rain" scenario on-site. They demonstrated the rapid connection of equipment pipelines,pressure adjustment, and emergency shutdown operations,and simultaneously explained the key points of daily maintenance such as hydraulic oil level inspection and pipeline leakage detection. This ensured that the operators of the customer side could initially master the basic operation skills. The photos taken on the spot clearly recorded the scenes where both parties jointly verified the equipment parameters,handed over technical documents,and demonstrated the drainage operation. This restored the rigorous and efficient delivery atmosphere.

This delivery in Shijiazhuang is an important practice for Huangshan Zhongguantai in deeply penetrating the flood control equipment market in Hebei Province. In the future, the company will continue to monitor the usage of the equipment and provide specialized technical support for the hydraulic system within the warranty period, helping the Shijiazhuang customers quickly transform the equipment into flood control practical capabilities, and providing safety protection for the local flood season.
