Hamm At last year's BMW show in Munich, a fully battery-powered tandem roller was shown for the first time.，These models are further refined. HD Compact Line Series，This series of models will first be introduced to the European market.。

Some models are equipped with oscillating steel wheels.，It also includes the world's first electric combined roller with oscillation.，These rollers do more than just compact with zero emissions.，And the noise is extremely low.。At the upcoming Wittgen China Technology Festival，One of the representative models HD 12e VV Will make its debut in China.，Guests invited to the event will have the opportunity to observe the event at close range.。

With eight compact electric rollers，Hamm Milestone achievement in the road roller industry。HD 10e (Drum width：1.00 m，Curb weight：2.5 t) Or HD 12e (Drum width：1.20 m，Curb weight：2.7 t) Has the same compaction efficiency as the sister model of the internal combustion engine。

The difference is that it can achieve zero emission when it runs.。As opposed to these machines.，Electric rollers reduce CO2 emissions by an average of 10% per hour kg，Operation of electric rollers and HD Compact Line Same as other machines in the series。

The low pressure system supplies energy for one working day.

A lithium-ion battery (Power 23.4 kWh) Through a 48 V The system is drive driven、Steering drive、Vibratory or oscillatory drive energization。When operating the low pressure system，Personnel are not required to have special qualifications。

The battery can be charged through a quick charging plug or a common plug.，Battery from 0% Charge to 100% Requires about 4 h (Quick charging plug) Or about 7.5 h (Common plug)。The battery is designed for use up to 45°C Operating at ambient temperature of，And provide enough power to the equipment within one working day。

Energy-saving drive

The driving device of the vibration or oscillation unit is purely electric，With special compact synchronous motor，This can double the efficiency.，With a corresponding reduction in energy demand。

The travel and steering motors drive the hydraulic system，All motorized components are maintenance free，And is known for its high torque.。Constant power is ensured by this design，Provide peak power when necessary。In addition，Most of the braking energy can also be recycled back into the system。

 HAMMTRONIC

HAMMTRONIC The Intelligent Compaction Control System monitors and controls the components of the Zero Discharge Roller。With electronic stick，Exceptionally convenient and precise machine control。Accelerate and brake using the appropriate travel slopes。

Overall programme for sustainability

Hamm The idea of saving resources is embodied in every detail of these electric rollers.。For example, the standard automatic motor stop system：When the machine is stationary，The system will disable all functions.，Thereby effectively saving considerable battery power.；At ECO (Economy) When working in mode，The control system will limit the travel speed，This can also achieve energy-saving effect.，As installed as standard LED Lighting。

The new steering control system also has an energy-saving effect.：In park position，The system consumes no energy at all.，Until the electronic stick is actuated，Will activate the steering motor，After that，The machine is powered by sensitive response characteristics and meets the requirements.，Allows the machine to turn easily。

Lectric combined road roller with oscillation：Compaction with low noise and zero emissions

Four of these electric models are equipped with oscillating steel wheels.，These include two combined rollers.。The already quiet oscillation function is ideally matched with the same low-noise electric drive.，The compaction equipment thus built works with low noise.、Zero emission，And bring very little vibration to the surrounding environment.。These compacting machines are particularly suitable for vibration and noise sensitive areas，For example, around a hospital or historic building。

No need for frequent maintenance

All motorized parts of the electric roller are completely maintenance-free。Due to further electrification，The amount of oil has been reduced by 70% Above。In general，Only a few on-vehicle wear parts require greasing or may be affected by wear。

That's why compared to diesel models.，The number of maintenance locations for electric rollers is surprisingly small。At the same time，Electric rollers have fewer operating hours than diesel models，Because the hours of operation counter is only activated when the steering column is deflected。
