With the development of science and technology,there is a higher demand for forestry and grassland fire fighting team carrying equipment.Therefore,a semi-crawler type fire fighting equipment was designed.In this paper,the structure design,the choice of engine,and the design of driving system of the semi-crawler type fire-fighting equipment for forestry and grassland was mainly introduced.It has the characteristics of simple structure,flexible steering,high driving speed and wide application range.The performance of semi-tracked fire-fighting equipment for forestry and grassland was also analyzed.The mechanics model diagram,mechanics relation and obstacle surmounting condition of the equipment were established.The change curve of the front wheel surmounting height with the center of gravity of the equipment was analyzed and calculated under different attachment conditions.This study provides an important basis for the loading weight and loading position of the carrier equipment.
