Screed Adjustment
调整油缸,使牵引点位于垂直行程的中间位置。
- 升高熨平板。
注: 如果使用的是液压可伸式熨平板,可以将熨平板伸展至所需的铺层宽度。
注: 如果在熨平板上安装了延伸装置,则必须调整其高度。 对于后延伸熨平板,应将延伸装置升高 6.3500 mm (0.25 in)。 对于前延伸熨平板,应将延伸装置降低 6.3500 mm (0.25 in) 。
- 在熨平板的两侧放置木块。 直接将木块放置在熨平板厚度控制装置的下方。 木块应足够长,可从熨平板的前端延伸至后端。
注: 木块的厚度应比所需的压实铺层的厚度厚 25%。 对于宽度固定的熨平板,木块长度应为 600 mm (2 ft) 左右。 对于液压可伸式熨平板,木块长度应为 1200 mm (4 ft) 左右。

- 降低熨平板,使其搁置在木块上。 向前拉动机器,直到松弛部分离开靠近牵引点的区域。
- 调节牵引点控制开关,以获得所需的作业迎角和高度。
- 转动熨平板端板的曲柄以使端板的履带板与坡度匹配。
