我国在冶金矿山、水利电力、铁路、建筑、国防等工程中,使用大量的装载机、铲运机、载运车等轮式装运设备。这些设备的轮胎,由于缺乏强有力地保护措施,在生产作业中,不可避免地与尖锐锋利的矿岩和碎石接触,致使轮胎在较短的时间内,被切割、扎穿、划伤、磨损而报废。因而,工程建设单位为购置轮胎所耗用的资金,相当于工程总费用的25％左右。在施工过程中,还常常因更换轮胎,不得不使主机停止作业。而对于较大型的工程轮胎,国
China’s metallurgical and mining, water conservancy and electricity, railways, construction, national defense and other projects, the use of a large number of loaders, scrapers, trucks and other wheeled shipping equipment. The tire of these devices, due to the lack of strong protective measures, inevitably comes into contact with sharp and sharp ore and gravel in production operations, resulting in the tire being cut, weared, scratched, Wear and scrap. Therefore, the project construction unit to purchase tires for the funds, equivalent to about 25% of the total cost of the project. In the process of construction, often because of the replacement of tires, had to stop the host operation. For larger engineering tires, the country
