XGMA XG6101D Double-drum vibratory roller

●Traveling speed realizes stepless speed change

The driving hydraulic system is a closed circuit composed of a manual servo two-way variable plunger pump and two fixed plunger motors.,The manual servo bidirectional variable plunger pump is connected with the diesel engine through the transfer case.,Two fixed plunger motors respectively drive the front and rear vibrating wheels to travel through the planetary reducer.,By pushing the handle of the manual servo valve on the drive pump,The road roller can realize stepless speed change and advance.、The function of retrogression。

●Double Steel Wheel、Dual drive、Double amplitude

XG6101DDouble drive of front and rear wheel,Ensure that the roller has good driving performance,The two vibrating wheels are driving wheels.,And is favorable for improving the quality of the pavement.,Front and rear wheels vibrate(It is also possible to vibrate the front or rear wheels individually),And improve that work efficiency and the compaction quality.。

●Drive and brake interlock

G6101D The series vibratory roller has successfully adopted the patented technology.——Walking hydraulic mechanism of road roller with operation protection device（Patent No：ZL 00 2 29863.5）,Interlocking protection of driving and braking of road roller can be realized，It works as follows.：

The drive pump is equipped with an electrically controlled brake valve,The brake valve is installed between the charge pump and the oil circuit of the manual servo valve.,When the brake valve coil is energized,The oil charge pump supplies oil to the manual servo valve and the brake oil chamber through the brake valve,The hydraulic thrust overcomes the spring force of the brake to release the brake,By actuate that handle of the manual servovalve,The road roller realizes forward or backward running.;When the brake valve coil is de-energized,The oil supply to the manual servo valve and the brake oil chamber is cut off,The brake works under the action of spring force.,At this time, the oil supply of the manual servo valve is also cut off.,Even if the manual servo valve handle is pushed,The swashplate angle of the drive pump does not Chan,The displacement of the drive pump remains at 0,So that that problem that the oil temperature of the hydraulic system rise and even the hydraulic components are damage due to the high-pressure overflow of the driving hydraulic system caused by mistakenly operating the handle of the manual servo valve when the road roll is in a braking state is avoided。

●And that brake is safe and reliable

The drive hydraulic system is a closed circuit,When the manual servo valve handle on the drive pump returns to the neutral position,Center the swashplate of the drive pump,The displacement of the drive pump is zero,Drive hydraulic system neutral self-locking stop,Road roller to realize service braking。

The two planetary reducers that drive the front and rear wheels are equipped with multi-disc brakes.,When the diesel engine shuts down or the brake valve coil on the drive pump loses power,Brake oil chamber cut off,Play a braking role,Reliable parking brake of road roller。

When the service brake fails due to the damage of the pressure oil pipe or other components in the driving hydraulic system and an emergency occurs,Emergency braking measures can be taken.,The emergency stop switch is pressed,Power loss of brake valve coil on the drive pump,De-energize the brake oil chamber,Braking function of brake,Road roller to realize emergency braking;At the same time, the manual servo valve also makes the swash plate of the drive pump return to the center due to oil cut-off.,The displacement of the drive pump decreases to zero.,The safety of the man-machine is effectively protected.。

● Achieve short distance dragging

BecauseXG6101D It is mainly applied to the 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 construction, XG6101D The driving hydraulic system of the tandem vibratory roller adopts the patent technology——Manual oil supply and towing hydraulic mechanism of road roll（Patent No：ZL 00 2 29862.7）,This function can be easily realized.。

When the roller breaks down(For example, the diesel engine cannot be started.)When unable to walk on its own,By operating the ball valve installed between the high and low pressure oil chambers of the drive hydraulic system,,O that the high and low pressure oil chambers of the driving hydraulic system are communicated,Supply oil to the brake oil chamber by operating the hand pump,Leave the brake in the released state,Use other existing traveling machinery on the construction site for traction,Short distance dragging can be realized,Remove the failed roller from the construction site.。

●Smooth start and stop of vibration

High grade highway has a high requirement for the smoothness of asphalt pavement.,Unevenness or cracking 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 start and stop of vibration of tandem vibratory roller shall be stable.。

BecauseXG6101DThe vibratory hydraulic system has a unique oil passage design.，The influence of hydraulic impact characteristics on the compacted material is greatly reduced.，So that that compaction performance is improve。

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

XG6101D Vibration and sprinkling can be set in automatic control state according to work requirements.,According to the preset speed,When the travel speed of the roller reaches the set value,Automatic vibration and automatic watering;Vibration and watering can be stopped automatically when the driving speed of the road roller is reduced to the set value.。

●Adopt the products of famous international companies

XG6101D The drive pump of the usesSAUER-SUNDSTRANDThe company's products,Vibrating pump、Vibrating motor、Vibrating valves are usedCOMMERCIAL-INTERTECHThe company's products,Vibrating bearings are usedSKFThe company's special vibration bearings,,All drive motors and planetary reducers areREXROTHThe company's products。

Due to the extensive use of international advanced technology and products,, XG6101D Tandem vibratory roller has superior performance.,High reliability and quality stability。
