Electrical lines and equipment need to be overhauled, tested and inspected in the long running process. In the early stage, these works need to be powered off, which will lead to power failure in residential areas and power failure in factories and enterprises, which will have a great impact on the production of factories and the lives of residents. Insulated bucket arm truck is required for continuous power maintenance.

The outrigger aerial live working vehicle with Ford F550 SUPER DUTY chassis is a medium-sized truck, but the total weight of the vehicle and cargo can reach 8.8 tons. The size of the Ma brand road tire is 225/70R19.5, with 19.5 inch steel rims.

Although the water storage is not large, it plays an important role in entering the fire site first, early warning, exploring the way, making isolation belts and treating the wounded, and provides first-line fire information for the later fire fighting of large forces and aircraft. In addition, this vehicle can also form a mobile water supply system for roads in forest areas to achieve the functions of local water intake and remote water supply.

The forest fire truck refitted from Ford F550 chassis has 350 horsepower, 635Nm high torque, GVW up to 8800kg, and the specific power even exceeds the U4000. With a small turning radius of 7-9m, the speed can reach more than 140mph. It is flexible and has strong trafficability.

The modular upper deck of forest fire fighting is used for multiple purposes. The modular upper deck scheme is designed according to the needs to improve the use efficiency, which can transport both personnel and equipment.
