一般的灰车车脚较宽,特别是车轴长出车轮以外。当内墙抹灰时,运灰车的车轴容易将门口碰坏,致使在木门口刷油前不得不重新整修一遍,既影响工程质量,又造成工料浪费。为解决这个问题,过去的习惯作法是抹灰前在门口钉护角,以免运灰车的车轴直接碰撞门口,而钉护角既麻烦又浪费工料。现介绍一种抹灰专用灰车,能较好地解决这个问题(见图1)。车盘的高度及长度均与原抹灰车相同,只是宽度有所变化,并在车盘的前面及两侧钉上6 General gray car feet are wider, especially when the axle grows out of wheels. When the interior wall is plastered, the axle of the lorry carrying the ash can easily damage the doorway, causing the oil to be refurbished again before brushing the oil at the wooden doorway, which not only affects the quality of the project, but also causes the waste of work materials. In order to solve this problem, it has been customary practice to nail corners at the door before plastering so as not to directly hit the axle of the ash transporter, which is both troublesome and a waste of workmanship. Now we introduce a special grey car for plastering that can solve this problem better (see Figure 1). The height and length of the chassis are the same as those of the original plastering vehicle, except that the width has changed, and the front and both sides of the chassis are nailed 6
