ABSTRACT

In Vietnam, there are hundreds of forest fire cases having occurred and thousands of hectares

of forest having lost annually, causing considerable economic, environmental and ecological damage. In

Vietnam currently, forest fire fighting equipments are very limited, the issue of forest fire fighting therefore

deals with a lot of difficulties. The state level project KC0713/06-10 has successfully designed and manu￾factured the multi-function forest fire fighting machine. This machine has been tested and given high ef￾ficiency of forest fire fighting. When operating to ensure safety of the multi-function forest fire fighting

machine, project studied the stability of the multi-function forest fire fighting machine in the forest there

is no way. This article introduces the result of the coordinates of the focus and stability calculates model of

the vehicle, built a moment balance equation, thereby determining necessary of horizontal slope for safe

the car operation in the forest without roads.

Keywords: Horizontal stability; Operation of multi-function forest fire fighting machine; Safe to

operation of forest fire fihting vehicle.
