Screed Adjustment
注: 当安装 AS2302C 或 AS3301C 熨平板时,不需要间隔装置牵引臂隔板。 当安装 AS4252C 熨平板时,必须使用间隔装置牵引臂隔板。
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扩展板,必须调整扩展器的高度。 为后扩展器熨平板升高扩展器 6.3500 mm (0.25 in)。 为前扩展器熨平板降低扩展器 6.3500 mm (0.25 in)。
- 在熨平板的每侧放置一个木块。 将木块直接放在熨平板的厚度控制装置之下。 木块应足够长,以便从熨平板的前部延伸到熨平板的后部。
注: 木块应比所需压实的沥青垫的厚度厚 25%。 对于固定宽度熨平板,木块应大约 600 mm (2 ft) 长。 对于液压伸出式熨平板,木块应大约 1200 mm (4 ft) 长。

- 降低熨平板以使熨平板接触到木块。 向前推机器,直到牵引点附近的区域绷紧。
- 转动厚度控制曲柄,直到曲柄位于卸载位置或松驰位置。 当曲柄位于卸载位置时,转动曲柄时可能会稍有阻力或没有阻力。

- 顺时针转动厚度控制曲柄 360 度。 转动厚度控制曲柄 360 度可以产生大约 2 mm (0.10 in) 的初始熨平板攻角。
- 转动熨平板端板的曲柄以使端板的履带板与坡度匹配。
