In the last issue of《Dimensional classroom》In the column，Xiaowei brought you the introduction of the relevant functions of Vogler's screed compaction device.，Current period《Dimensional classroom》Will take Uyghur fans to learnRelevant knowledge of rammer stroke and matters needing attention during construction。

As an important component in the paver screed compaction system，By vertical movement up and down，The rammer will pre-compact the paving material on the front side of the screed，So that that compactness and the flatness are improve。The distance that the rammer head moves up and down is also called the rammer stroke.，So what are the effects of different rammer strokes on the paving construction of materials?？

Generally speaking，The longer the rammer strokes，The compaction effect and depth are also ideal.。The Vogler screed ram stroke can be set to 2 mm、4 mm、7 mm、8 mm Different options for，Can be respectively suitable for that pave of the ultra-thin asphalt material、Most conventional bituminous material、Paving of asphalt material and cement concrete material with large thickness。

In the actual paving process，We can adjust the screed ram stroke both mechanically and hydraulically，Let's follow Xiaowei to learn how to adjust the stroke of the rammer in the construction process through the video.！

《Dimensional classroom》It is a video column produced by Wittgen China Technology and Training Center to introduce equipment operation and precautions.，Launch on a regular basis，I hope you will continue to pay attention.。In addition，If Uyghur fans have questions they want to know，You can also leave us a message.。
