俗话说:“人要衣装,佛要金装”。最近,看到几台装车待运的工程机械产品,深有其貌不扬之感。一台新机器制成后,其性能是否符合设计要求、零部件质量是否合格,固然至关重要,但外观质量也是不容忽视的。工程机械多系自行式机械,不是安装在厂房内部,而是经常在露天进行作业,日晒雨淋。在地理和气候条件差的野外,还会受到砂石的敲击。工程机械本身的工作条件也很恶劣,经常跟泥砂、碎石、废渣 As the saying goes: “People want clothes, and Buddha needs gold.” Recently, I saw a few truckloads of construction machinery products, which are very unpredictable. After a new machine is manufactured, whether its performance meets the design requirements and whether the quality of components is qualified is of course crucial, but the appearance quality cannot be ignored. Construction machinery is mostly self-propelled machinery. It is not installed inside the factory but it is often operated in the open air and exposed to the sun and rain. In the poor geographical and climatic conditions, sand and gravel will also be struck. The working conditions of the construction machinery itself are also very bad, often with mud sand, gravel, waste residue
