The 6×6 Category III special chassis is an all-wheel drive, highly adaptable heavy-duty special modified chassis. It is a basic supporting chassis for special vehicles. It retains the complete frame, walking, power and transmission systems, and has no bodywork configuration. It can meet the installation and modification needs of various special equipment, and is widely adapted to special vehicle modification scenarios such as engineering operations, emergency rescue, and field operations.
The chassis adopts a six-wheel all-wheel drive structure, is equipped with a high-power diesel engine, and is matched with a multi-speed manual transmission. It has sufficient power reserve, high transmission efficiency, and excellent starting and climbing performance. The chassis is equipped with a high-strength overall frame, special off-road suspension, large-pattern off-road tires, and large-loading front and rear drive axles. It has strong load-bearing capacity and excellent shock absorption performance. It can easily adapt to complex and harsh road conditions such as mud, sand, mountain roads, and mining areas. Its passability and stability are far superior to ordinary chassis.
The overall design adopts a modular design, with a regular structure, sufficient space reserved for modification, and standardized interfaces to facilitate the later installation of cargo boxes, tooling equipment, rescue devices, etc. At the same time, the chassis has the characteristics of good low-temperature starting performance, low failure rate, strong durability, wide adaptability to working conditions, and outstanding reliability and practicality. It is the core basic chassis for heavy-duty special purpose vehicle modification.
