现代设计和制造的土方机械,在各种施工条件和要求下,可以快速而高效地进行挖掘、运输、卸土工作。但要充分发挥这些机械在经济效益上巨大潜力,只有针对工程合理选配施工机械,以最小的费用和循环运送最大量的土方,才可达到最高的利润。 Modern earth-moving machinery designed and manufactured can quickly, efficiently and excavate, transport and unload soil under various construction conditions and requirements. However, it is necessary to give full play to the great potential of these machines in terms of economic efficiency. Only by selecting the appropriate construction machinery for the project, and transporting the largest amount of earth at the minimum cost and cycle, can the maximum profit be achieved.
