Product Advantages

 

1.Low fuel consumption

Casting energy-saving main valve: response and reversing speed increased by 20%, reversing impact decreased by 10%, hydraulic parts life increased by 50%.
Engine power self-matching: the pumping displacement and engine speed, power, torque and fuel injection can be adjusted adaptively, and the engine speed can be dynamically matched according to load changes, and the engine always works in the economic and fuel saving area.

2.High efficiency

Fast suction: the installation Angle of the pumping system is optimized from the traditional 10-11 degrees to 8 degrees, and the suction efficiency is increased by 10%, and the measured value is as high as 95.2%.

3. Safety

External connecting rod and through shaft structure: the connecting end of the boom is more rigid, better handling, and the rotating swing amplitude is reduced by more than 20%; The end vibration amplitude can be controlled at ±20cm.
The turntable is connected to the boom through the shaft structure: the connection rigidity is better, which is conducive to shock absorption and anti-swing of the boom.
New optimized transmission pipe support: stress at each point is less than 100MPa, no cracking.
The reducer is configured with plunger motor: more accurate rotation positioning, safer and more reliable control, and 0.7-1.5 times higher accuracy.
Comprehensive online monitoring: reverse camera, reverse image

4. Intelligence

Digital cylinder: master cylinder stroke utilization rate can reach 99.5%, realize stroke adaptive correction, intelligent fault diagnosis.
The device location information and driving path can be viewed in real time on the mobile terminal;
Equipment conditions, fuel consumption, pumping working time, standby time and other basic parameters;
The device can be actively alerted to abnormal operation. For example, the chassis water temperature is high, the pump oil temperature is high, the pumping state pressure impact abnormal warning function;
Electronic fence function: set the equipment driving work safety area, beyond the safety area for active early warning;
Active equipment maintenance prompts, such as replacement of conveying pipes, concrete pistons, etc.

5.Fuel consumption management system

Daily fuel consumption of the equipment, fuel consumption of the pumping side, refueling time, etc. can be viewed in real time;
Self-diagnosis engine fuel consumption health state, engine high fuel consumption state early warning;
Send fuel information to the customer's mobile phone.

6.Easy maintenance

Lubrication-free bearing: rear leg lubrication-free, no maintenance; Boom pin lubrication period is extended by more than twice.
Lightweight hollow structure turntable: lighter weight, providing more space for conveying pipe and hydraulic line maintenance.
