首先，违章操作，不仅直接损坏高空作业车，而且严重的还会造成人身伤亡。03011高空车，由于平时不按操作规程操作，在升高大、小臂时，为图方便，经常超角度使用，在大小臂夹角大于70度的范围内操作施工，结果，一次在太榆路施工时出现了小臂腰折，造成小臂。
    First, the illegal operation, not only directly damage aerial vehicles, and will result in severe injury or death. 03011 aerial vehicles, due to usually do not follow the rules and operation at elevated large, arm, to facilitate the map, often ultra-angle to use, operate within the range of the size of the construction arm angle greater than 70 degrees, the result of too much time in Elm Road the emergence of the construction arm waist fold, causing the arm.

    在工作时下滑，还有对升降斗的载物的重量，产品出厂时限载量为25OKg，实践证明这一限载量并不是一成不变的，经过数年的使用，支撑升降斗的相关部件由于材质磨损、拉力减弱、焊接强度下降，升降斗的限载量要逐年减小，一般来说，要按每年减少5公斤建立定人定车保养责任制，严格按规定要求做好平时的保养，并落实相应的考核制度。
    Fell at work, as well as to lift the weight of the bucket loading, loading of factory time 25OKg, this proved not static load limit, after several years of use, support lifting the bucket related components due to material wear and tear, tensile weakened, weld strength decreases, limiting the amount of lift bucket load to be reduced year by year, in general, according to an annual reduction of 5 kg vehicle maintenance man-given responsibility to establish, in strict accordance with the requirements to do the usual maintenance and implement appropriate appraisal system.

    其次，除了执行定期的大、中修保养规定外，十分强调平时及时发现和解决一些不起眼的小问题，以做到防微杜渐。1d此要求经常对机械打黄油，补充电解液，加润滑油，加水，轮胎补气，其中对液压部分应按时补充液压油，堵塞跑、冒、滴、漏等现象，使机械设备经常处于完好状态，保持车辆内外清洁，保证有良好视线。
