Liugong E series double drum compactor adopts industry-leading core technology such as Liugong non-impact vibration technology, 67Hz high frequency technology and flexible start-stop control technology. Its comprehensive performance is leading domestically and catching up with international standards; it has high reliability and high construction. Efficiency and high-pressure solid quality, compaction effect meets the stringent requirements of highway smoothness σ ≤ 0.6, compactness > 98%, is the compactor of high-grade highway asphalt surface layer!
Appearance
I. Liugong non-impact vibration technology - high reliability of vibration system
Flow ball structure, special eccentric cavity, steel ball and anti-wear agent inside, replacing the eccentric block of the block vibration exciter, generating large and small vibration through the movement displacement of the steel ball;
When starting and stopping vibration, the steel ball realizes flexible start and stop under the buffer of anti-wear agent, avoiding the instantaneous impact of the stop vibration of the block vibration exciter and stopping the limit pin, eliminating the risk of eccentric block fracture and ensuring high reliability of the exciter. ;
Avoid the vibration and shock, and effectively extend the service life of the exciter, vibration bearing and eccentric shaft to ensure high reliability of the vibration system;
At the same time, the non-impact exciter does not contaminate the bearing lubrication system by the metal fragments generated by the impact of the block type vibration exciter, which greatly reduces the maintenance cost.

Second, 67Hz high frequency technology - high efficiency and high construction quality
Efficient: The compaction speed of 67Hz high-frequency vibration can reach 7.2km/h, compared with the compaction speed of 5.1Hz/h at 48Hz, and at the same time match the larger exciting force, the compaction efficiency is increased by more than 41%;
High construction quality: 67Hz high-frequency vibration can achieve more than 99% compaction of asphalt surface lamination, and 48Hz vibration increases the number of compaction passes.
Suitable for more working conditions: 67Hz high frequency vibration is suitable for ultra-thin layer asphalt and asphalt overlay on bridge.
67Hz vibration frequency achieves better compaction
Third, flexible start and stop control technology - high flatness
The electric proportional control handle is combined with the self-developed "soft acceleration and soft deceleration" control technology; the flexible starting and braking are realized to avoid the occurrence of material and cracks in the layup, and to ensure the high level of flatness.

Fourth, international support - high reliability
British imported Cummins engine
The whole system is equipped with imported Cummins engine from Britain and 113kW high-power engine. It has stable and reliable performance and long service life.
Independent intelligent cooling technology is adopted, the electric proportional fan is used for heat dissipation, and the fan speed is intelligently adjusted according to changes in water temperature, oil temperature and temperature;
At the same time, it has an automatic idle speed function, and the overall fuel saving is over 8%.
