道路施工机械使用到一定时期后就有个更新问题。施工机械的合理更新是获得最大经济效益,是关系到维持简单再生产或扩大再生产的重要问题。林区道路的主要施工机械是六十年代初,在国内或国外购进的产品。由于使用至今,时间较长,它们大部分已陈旧或技术状态不够良好,更新问题显得较突出。研究道路施工机械更新问题,首先须分析一下机械的重置年限。
Road construction machinery used to a certain period of time there is an update problem. Reasonable renewal of construction machinery is to obtain the maximum economic benefit, which is an important issue related to the maintenance of simple reproduction or expansion of reproduction. The main construction machinery for the forest roads is the products purchased domestically or abroad in the early 1960s. As they have been used so far, most of them are outdated or the technical condition is not good enough, and the problem of renewal becomes more conspicuous. Research on road construction machinery renewal problems, we must first analyze the mechanical reset life.
