露天矿道路的日常维护工作种类繁多,要用大量专用技术装备,而且这些装备多为季节性作业。此外,成批生产的露天矿通用汽车道维护设备多为低功率和低效率的设备。为了提高日常维护工作效率和质量,必须有可供一年四季均可使用的多功能大功率设备。为解决这个问题,苏联冶金工业部和煤炭工业部有关企业和单位利用露天矿自卸汽车底盘改装成几种撒砂用的工业试验样车。本文将介绍以下几种专用车的结构。 Open pit road maintenance of a wide range of routine work, to use a large number of specialized technical equipment, and most of these equipment for seasonal operations. In addition, mass production of open pit General Motors Road maintenance equipment, mostly low-power and low efficiency equipment. In order to improve the efficiency and quality of routine maintenance work, there must be a multifunctional high-power device that can be used all year round. To solve this problem, the Soviet Union Ministry of Metallurgical Industry and the Ministry of Coal Industry enterprises and units using open-pit dump truck chassis converted into several kinds of sand used in industrial test-like vehicles. This article will introduce the following types of special vehicle structure.
