The new generation of Hummer HD Series double-drum roller is specially developed for the Chinese market，Combine the advantages of Hummer Road Roller Family，Intelligent、High yield、High compaction quality in one。

HAMMTRONIC The intelligent compaction control system can precisely control the walking system and compaction vibration system of the equipment.，Uch as cruise control、The vibration frequency is constant、Automatic start and stop of vibration, etc.，The operation difficulty of that operator is greatly reduce，Reduce the error and quality hidden danger caused by artificial control，Got it HAMMTRONIC Intelligent control system，Novice can also become an old driver in seconds！

Construction site：Nanning, Guangxi Province—Zhanjiang Expressway

Compacted material：Middle layer AC120 asphalt concrete material

Compacted thickness：6 cm

Compaction process：60 Hz High frequency vibration mode

Compaction speed：6 km/h

Introduction of highlights

Nanning—Zhanjiang Expressway is an expressway connecting Nanning City, Guangxi Zhuang Autonomous Region and Zhanjiang City, Guangdong Province in China.，It is one of the 11 provincial corridors connecting Guangxi with the expressway network of Guangdong Province. ，It is also the expressway network of Guangxi.“1 ring, 12 horizontal, 13 vertical and 25 links”In the planning layout“Lian 13”。As a key project，The construction of this expressway is very strict in terms of surface quality control.，The project featured the Vogler Super 2100.-3 L With the Hummer HD Series classic models HD 138 and New Generation HD 148i VV Collaborative work。

In this project，Man-pilot HD 148i VV The high-frequency heavy-duty double steel wheel is set to 60 by one key on the control panel. Hz Vibration frequency。In the subsequent operation process, there is no need to be the same as the old model.，You need to adjust the throttle by hand to control the frequency.。Equipment is not affected by engine load，Maintain a steady frequency throughout the compaction operation。

It's even easier.，HD 148i VV Have AUTO Automatic vibration starting and stopping function，The operator opens it AUTO After the key，HAMMTRONIC Intelligent compaction control system is like the nerve center system of the equipment.，The driving speed can be monitored in real time，Automatic start of vibration when the equipment enters the reasonable driving speed range，And stop vibrating when this travel speed range is exceeded。

With the cooperation of the operator HD Maximum travel speed setting function for new model，The device can not only turn on the vibration automatically、There is no need to worry about overspeed compaction caused by misoperation when vibration stops.。The operator only needs to push the handle to control the equipment forward.、Back off，Turn the steering wheel when necessary.，The compaction operation can be completed by the equipment itself through the intelligent compaction control system.。

In the large-scale backlog of practical work projects such as highway rush work.，HD 148i VV Intelligent vibration function can not only greatly reduce the labor intensity of the operator，Moreover, the compaction operation can be less influenced by the practical experience and operation level of the operator.。It also means，Not only is the operator more efficient，The compaction control is more precise, so that the overall compaction quality is further improved.。

   With Vogler Super 2100-3 L Homework，After the initial pressing, the surface layer has shown a high degree of flatness.

   60 Hz High frequency vibration，Compaction speed is maintained at 6 km/h，Handheld operation is comfortable and easy

New model of Hummer with double steel wheel HD 148i VV With the other two Hummer classic double steel wheel model. HD 138 joint operation，After driving the new model, the driver who had previously driven the Hummer's double steel wheel operation gave feedback.：“Equipment control is very intelligent.，A lot less action.，It's easy to work.，Efficiency is also high。”

Wei has something to say

The new generation of Hummer HD Series double-drum roller is popular with users for its excellent compaction quality and more intelligent and fast compaction control system。In addition，High cost performance and lower maintenance costs are also your best choice.。

The promotion activities and test drive activities of the four new products of Wirtgen agents in China are in full swing.，You are welcome to contact the local agent of Wittgen in China to understand and personally experience the new machine.。
