Not long ago, the Yuzhou fire brigade ushered in two new “comradesâ€â€”two 53-meter ascending platform fire engines worth RMB 4.7 million each. They were stationed in Longhai City and Zhangpu County Fire Brigade.
According to reports, the fire truck has five synchronous telescopic arms and one folding arm, which can reach as high as 53 meters. The height of the platform is equivalent to the height of 15-18 floors. This special fire-fighting vehicle adopts a Mercedes-Benz universal chassis and is hydraulically driven. The platform is rated for 400 kilograms and can carry 4-5 people, and can achieve 360-degree full-rotation operation. The fire-fighting system water pipes are packaged synchronous retractable pipes, and the ascending platform is equipped with high-pressure water cannons.
Wang Dequan, a technician of the Luzhou Fire Fighting Brigade, said that this vehicle can not only be used to save people at high altitude, but also play an important role in high-rise buildings, large-span factory buildings, and oil fire fighting operations.
