XGMA XG6131D-I Double Steel Wheel Roller

●Stepless speed regulation of driving speed

The hydraulic drive system is a closed circuit composed of an electric proportional servo bidirectional variable piston pump and two fixed displacement piston motors.。Operating electric proportional control handle，The road roller can realize stepless variable speed forward、The function of retrogression。

●Dual drive、Double-amplitude and three-frequency machine front and rear wheel double-drive,Ensure that the roller has good driving performance,The two vibrating wheels are driving wheels.,Is beneficial to improving the quality of the compacted surface.,Both front and rear wheels can vibrate(It is also possible to vibrate the front or rear wheels individually),And improve that work efficiency and the compaction quality.。 This machine sets two kinds of amplitude.，Three vibration frequencies，More adaptable to working conditions。

●Patented technology

This product uses a number of our company's patented technology.，Respectively：Walking hydraulic mechanism of road roller with operation protection device（Patent NoZL00 2 29863.5）Manual oil supply and towing hydraulic mechanism of road roll（Patent No：ZL 00 2 29862.7）And a method for stably starting and stopping the vibration of the vibratory road roller.（Patent No：ZL201010204617.7）。

ZL 00 2 29863.5. The application of patented technology can realize the interlocking protection of driving and braking of road roller.，If the drive control handle is pushed when there is a malfunction, that is, the brake is not released,，The swashplate angle of the drive pump does not Chan，Effectively protect the driving hydraulic system and brake。

This product is mainly used for compaction of asphalt pavement.，When the roller breaks down，It shall be towed away from the construction site in time.，So as not to affect the quality of construction and pavement。ZL00 2 29862.The application of the patent 7 can conveniently realize the short-distance dragging of the road roller。

First of all, adopt the internationally advancedPLUS+1 Software artificially optimizes various electrical signals，The inertial impact is greatly reduced.，Not only does the compacted pavement have good flatness,，But also greatly improve that performance of the diesel engine,、Service life of hydraulic components。Its comprehensive technical performance has reached the international advanced level of similar products.（Its patent number is：ZL201010204617.7）。

●Reliable three-stage braking function

XG6131DD-IThe tandem vibratory roller can effectively realize the function of three-stage braking，The service brake、Parking brake and emergency brake，It can ensure the effective braking of the road roller under various dynamic and static conditions.。

●Adopt the products of famous international companies

XG6131D-IDriving pump for tandem vibratory roller、Vibrating pump、The vibration motor is usedSAUER-SUNDSTRANDThe company's products,Vibrating bearings are usedSKFThe company's special vibration bearings,Sprinkler pump is usedFLOJETThe company's products,The drive motor and the planetary reducer adoptREXROTHThe company's products，The battery is PentiumN120 solid battery。Due to the extensive use of international advanced technology and products,, Therefore, the product has superior performance and high reliability.。

●Vibrations can start and stop quickly

High grade highway has a high requirement for the smoothness of asphalt pavement.,Unevenness of the asphalt surface due to local over or under compaction of the asphalt pavement shall be avoided,Therefore, compaction equipment for asphalt pavement is required.─The vibration stop or start speed of the tandem vibratory roller shall be fast.。

The hydraulic vibration system of this product adopts high quality relief valve.,Its response time is short.,About 20ms,The set pressure of the relief valve is much higher than the working pressure of the vibration system.,It can ensure the rapid start of vibration.。The front and rear wheel hydraulic vibration system is an independent closed hydraulic system.，When the swash plate of the vibratory pump returns to the neutral position，The vibration can stop quickly.。

●Vibrating wheel can realize multi-frequency vibration

The hydraulic vibration system of this product adopts double variable piston pump and double fixed piston motor system.。Vibration pump adopts double pumps in series，The displacement is controlled by the electric proportional valve.，Multiple frequencies can be realized，This machine is set with three frequencies。The front and rear wheel vibration hydraulic systems are independent closed hydraulic systems.，Can be separately controlled，It can realize the vibration of front and rear wheels simultaneously or any single wheel.。

●Start and stop of vibration、Sprinkler can be controlled automatically or manually

This product can set the vibration and sprinkling in the automatic control or manual control state according to the work needs.,Free switching between the two。In the automatic control state，According to the preset speed,When the travel speed of the roller reaches the set value,Will automatically vibrate and automatically water;Vibration and water spraying are stopped automatically when the travel speed of the roller is reduced to the set value.。In the manual control state，It can be manually controlled according to actual needs.。

●At the same timeXG6131D-ITandem vibratory rollers also have other major features.：

(1)．First of all, adopt the internationally advancedPLUS+1 Software artificially optimizes various electrical signals，To control the start of the machine.、Start vibration、Stop vibrating、Smooth transition of parking，The inertial impact is greatly reduced.。Not only does the compacted pavement have good flatness,，But also greatly improve that performance of the diesel engine,、Service life of hydraulic components。

(2)．The hydraulic system consists of electrically controlled proportional hydraulic pumps,、Motor composition。

(3)．LCD centralized display，At a glance。

(4)．Vibration frequency at 35——45Hz Between stepless adjustable，Convenient selection of stepless change of exciting force，Suitable for a wider range of construction processes。

(5)．Equipped with induction speed measuring device，And that instantaneous travel speed is displayed in the centralize display screen。Facilitating the operator to control the working speed。

(6)．The amount of water sprinkled varies with the stepless change of driving speed.。

(7)．The noise value of the whole machine is lower than that required by the national standard.。

(8)．The appearance is beautiful and elegant。
