Liugong E series double steel roller by Liugong vibration technology and 67Hz technology, the core technology of high frequency flexible stop control technology industry leading shock without impact, the comprehensive performance of the leading domestic and international catch-up; with high reliability, high efficiency and high quality construction, compaction effect satisfy the flatness of less than 0.6. Density > 98% of the stringent requirements, is the compactor of high grade highway asphalt pavement!
First, Liugong non impact vibration technology - vibration system, high reliability
The utility model relates to a flow ball type structure, a special eccentric cavity, and a steel ball and an anti friction agent are arranged in the eccentric cavity to replace an eccentric block of a swing block exciter, and a vibration is generated through the movement displacement of the steel ball;
When the vibration is started and the vibration stopped, the steel ball can realize the flexible stop and stop under the anti friction agent buffering, and can avoid the instantaneous impact of the block vibration exciter to stop and strike the limit pin, prevent the risk of the eccentric block breaking and ensure the high reliability of the vibration exciter;
The utility model can avoid starting stop shock and vibration, effectively prolonging the service life of the exciter, the vibration bearing and the eccentric shaft, and ensuring the high reliability of the vibration system;
At the same time, there is no shock absorber, no block type vibration exciter, metal debris produced by impact, pollution bearing lubrication system, greatly reduce maintenance costs.
Two, 67Hz high frequency technology high efficiency and high construction quality
High efficiency: 67Hz high frequency vibration compaction speed of up to 7.2km/h, compared to 48Hz compaction speed of 5.1km/h, while matching greater excitation force, compaction efficiency of more than 41%;
High construction quality: 67Hz high frequency vibration can realize the compaction of asphalt surface layer more than 99%, increase the vibration of 48Hz, and the number of compaction is difficult to reach;
Applies to more cases: 67Hz high frequency vibration for thin layer of asphalt and asphalt pavement compaction on bridge.
Three 、 flexible start stop control - Gaoping integrity
The electric proportional control handle is adopted to combine the self-developed soft acceleration and soft deceleration control technology to realize flexible starting and braking, avoiding the occurrence of material and cracks on the floor, and ensuring the smoothness of the high pressure.
Four, international matching - high reliability
Cummins Engine imported from Britain
The whole department is equipped with Cummins Engine imported from the UK, 113kW high-power engine with stable and reliable performance and long service life;
Adopt independent intelligent heat dissipation technology, fan with electric proportion, fan speed is adjusted according to water temperature, oil temperature and temperature;
At the same time, with automatic idle function, comprehensive fuel saving of more than 8%.
Imported Germany Rexroth hydraulic system
The whole system is equipped with imported German Rexroth hydraulic system, including vibration hydraulic system pump, motor and hydraulic drive system of the pump, motor and reducer;
All use heavy duty series model, easy to deal with bad conditions, hydraulic system more stable, long service life.
Five 、 comfortable and efficient driving
The front and rear wheels can realize independent single vibration, and satisfy the compaction operation of asphalt joints;
At the same time with the crab with 160mm function, left and right rotating seat, console and dashboard, convenient side pressing;
Vibration and sprinkler are optional in both automatic and manual mode, and automatic vibration and automatic sprinkling according to compaction speed;
Convenient and efficient operating handle, integrated crab (on the left and right), vibration (lower left) and crab in the back (right) button;
Far better than counterparts, 1 meters x 1 meters of view, 0.65 meters before the first 1 meters, 0.76 meters after 1 meters of field of vision, the field of vision is more open, and can clearly observe the steel wheel and sprinkler work;
Standard cab, air conditioning, three shock, three intermittent sprinkler, fault alarm function LCD dashboard, USB interface with the radio player, and weight adjustable seats, and adjustable operating platform, easy to navigate the various conditions!
Six 、 convenient maintenance
With fault alarm function, liquid crystal combination instrument, with fault alarm, electrical centralized control box, fault maintenance all remind;
The hood and the low center of gravity vertical lifting type full open, stand on the maintenance point at your fingertips.
The products include 12 tons of CLG6212E, 13 tons of CLG6213E and 14 tons of CLG6214E, and each tonnage model has high frequency and intermediate frequency. It is suitable for compaction of asphalt surface layer of high-grade highway!
