我省机械化养路的研究工作,是从1961年开始正式进行的。机械化的动力主要是利用新会县农机厂出产的“圭峰-7型”手扶拖拉机,因它具有构造简单、轻巧灵活、驾驶易、耗油少等优点。经过两年多的摸索试验,初步认为该项手扶拖拉机可以担负短距离的养护砂石材料的运输,和简单的养护操作;可以进一步减轻体力劳动强度,提高工效,节约畜力、人力。“圭峯-7型”手扶拖拉机原是农业用的机械。改用于公路养护是经过几年试验改进的,1961年以改进运料、回沙的拖挂工具为主,基本试制完成。1962年继续研究改
The mechanization of road maintenance in our province, from 1961 onwards. Mechanization of the main force is the use of Xinhui County Agricultural Machinery Factory produced “Guifeng-7” walking tractor, because it has the advantages of simple structure, lightweight and flexible, easy to drive, less fuel consumption. After more than two years of groping experiment, it is initially believed that the walking tractor can bear the transportation of short-distance cured gravel materials and simple maintenance operation; and can further reduce physical labor intensity, improve work efficiency, save livestock and manpower. “Gui Feng -7 type” tractor was originally used for agricultural machinery. Change to road maintenance is improved after several years of testing, in 1961 to improve the transport of materials, sand back to the main drag-and-drop tools, the basic prototype completed. 1962 continue to study change
