40 years ago，Hummer has developed a revolutionary new compaction technology.—— Oscillatory compaction。This intelligent and fast compaction process has established the leading position of Hummer in the field of compaction technology and market today.。

Nowadays，One out of every four Hummer tandem wheels is equipped with oscillatory compaction technology.，Hummer is also the only company that can build both for the road.，Manufacturers that also offer oscillatory compaction technology solutions for earthmoving operations。From 2.5-ton to 14-ton，From small rollers to heavy double steel wheels，Hummer has more than 35 oscillating models.，It can meet various application requirements of customers.。（Click on the video to see 40 years of Hummer Oscillation Technology）

More efficient and widely used compaction technology

This new compaction technology is recognized by the market.，The reason for the success is that：Oscillating rollers are designed to achieve fast、Efficient、Designed for high quality dynamic compaction。Compared with double-drum vibratory roller，Twin-drum compactors equipped with one oscillating drum and one vibrating drum achieve at least the same degree of compaction with fewer passes。

What's more,，Oscillating steel wheels do not leave the ground during compaction，So that that resonance is hardly transmit to the surrounding area，This makes in the bridge、Thin layup or vibration sensitive area（For example, downtown、Railway、Industrial plant、Surrounding historic buildings）It can also be dynamically compacted。

In addition，Another significant advantage of the oscillating roller is the extended temperature range of application，Even in low temperature or cold air environment and low asphalt temperature conditions，Oscillatory compaction also ensures an increase in the degree of compaction，Without crushing the aggregate。Oscillatory compaction also ensures good tightness and durability at the joint，Will not cause any damage to the cooled asphalt。In a nutshell，Oscillatory compaction technology has a wider range of applications.。

 

Time-tested Widely favored

It is due to the Hummer oscillatory compaction technology that the scope of dynamic compaction applications has been broadened.，Work efficiency and compaction quality are improved.，It has passed the test of practice and has been recognized by global customers.。So far，There are more than 7000 vibratory rollers in use worldwide.，Capable of compacting more than 3 per week,500 km of new roads。In the past five years,，Sales of Hummer oscillating rollers have more than doubled.。

In the Chinese market，Hummer oscillation technology is also widely recognized.，It has been successfully applied for many years.。Hummer Large Oscillating Roller in Chengdu Second Ring Viaduct、Pavement compaction of Kunming-Chuxiong Expressway Tunnel，And the Hong Kong-Zhuhai-Macao Bridge、Humen Bridge、Haiwen Bridge in Hainan、Shanghai-Nantong Yangtze River Bridge、Chongqing Yangtze River Bridge、Huangpu Bridge and other super bridge deck compaction and other large-scale projects.，Not only the compaction of asphalt with high quality is realized,，But also achieves excellent effects in the aspects of environmental protection and cost saving.，It has been highly praised by the construction party.。（Click the picture to see some successful application cases of Hummer oscillation technology in the past.）
