现今在对公路、铁路以及建筑施工时,推土机是其经常应用的设备。并且推土机也是土木方工程机械中经典的机械之一,其运用了力学中的摩擦、转动以及做工等知识进行施工并且其在工作中非常的灵活。推土机在建筑施工中的广泛应用,致使一些存在于推土机中的故障逐渐的显现出来,影响了工程的进度,使施工企业的成本增加。为预防故障的出现,对推土机日常维修以及推土机性能的改进逐渐的受到人们的关注,针对预防推土机的故障以及性能的改进进行了描写,希望能够对推土机的使用者有所帮助。 Bulldozers are often used in the construction of roads, railways and buildings today. And bulldozers are also one of the classic machines in civil engineering machinery that uses knowledge of friction, turning and workmanship in mechanics and is extremely flexible at work. Bulldozers in the construction of a wide range of applications, resulting in some of the faults in the bulldozer gradually emerged, affecting the progress of the project, so that the cost of construction companies. To prevent the emergence of faults, bulldozers routine maintenance and bulldozer performance improvement gradually by people’s attention, for the prevention of bulldozer failure and performance improvements were described, hoping to bulldozer users to help.
