Due to the impact of heavy rainfall, a bridge in Guanzhuang Town, Yuanling County, Huaihua, Hunan Province was damaged. On June 22, a 26-meter emergency mechanized bridge manufactured by China Harzone was sent by the National Regional Highway Traffic Emergency Equipment and Material Reserve Center in Hunan (Loudi) to the rescue site. Meanwhile, China Harzone dispatched technicians to give technical guidance.

After receiving the rescue and relief instructions, the emergency rescue personnel from China Harzone rushed to the scene at the first time, overcoming the difficulties of poor road conditions, humidity, high temperature, etc. Then, they assisted the Center to actively carry out the site investigation and bridge erection without a stop. Finally, on the evening of June 23, the 26-meter emergency mechanized bridge was completely erected, opening up the emergency rescue channel and guaranteeing the normal passage of local people.
