In the last issue of《Dimensional classroom》Li Xiaowei explained Wittgen to everyone. SP 15 Operation mode of outrigger swing function of slipform paver，Current period《Dimensional classroom》Xiaowei will take his fans to learn about Hummer Road Roller. ECO Pattern。

As fuel prices continue to rise,、The soaring cost of use and the growing awareness of environmental protection.，Choosing a suitable earthwork compacting equipment also becomes crucial.。ECO Generally speaking, the pattern is a set. Ecology（Environmental protection）、Conservation（Energy saving）、Optimization（Optimize）An integrated model.，No ECO If the mode roller reduces the engine speed in order to reduce the fuel consumption,，The frequency of drum vibration will naturally decrease，The compaction work will be proportionally reduced accordingly。

And have Hammtronic Hummer roller with intelligent control system，It carries ECO The mode can be realized when the engine speed is reduced.，Automatically adjusting the control current of the vibration pump to compensate for the loss of compaction work，The vibration frequency and the exciting force remain constant even at low engine speed。

《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 you have any questions you want to know, you can also send us a bullet screen or leave a message.。
