XCMG 25-ton crane remote throttle fault repair?

1. Remote throttle fault repair of XCMG 25-ton crane?

In order to work smoothly and safely, with stable hydraulic oil pressure, cranes and excavators also require stable power output. Under normal circumstances, no repair is required.

2. XCMG crane computer fault codes and solutions?

E01: The working amplitude is too small or the boom angle is too large

Cause: The amplitude exceeds the minimum amplitude of the performance table or the angle is higher than the maximum angle of the performance table

Solution: Change the amplitude downward to the amplitude allowed by the performance table or Angle

E02: The working amplitude is too large or the boom angle is too small

Cause: The amplitude exceeds the maximum amplitude of the performance table or the angle is lower than the minimum angle of the performance table. The reason is that the downward amplitude of the luffing main arm is too large

Solution: Zoom upward to the amplitude or angle allowed by the performance table

E04: The working condition does not exist or the rotation area is not allowed

Cause: A non-existent working condition code was selected, and the main arm is in the rotation area that is not allowed

Solution: Set a correct working condition; rotate to the allowed working area

E05: The length of the boom is not within the allowed length range

Cause: The main arm extends too much or is not long enough; the length sensor is adjusted

Solution: The main arm telescopes to the correct length; replace a set of coil springs including the driving wheels, and then adjust the length sensor as above

3. How to adjust the XCMG crane computer?

1. First, make sure that the boom cable box has been installed and fixed.

2. Open the cover of the cable box, and the length detection potentiometer is installed inside the cable box. The cable connected to pin 3 of the four-core hole on the back of the intelligent monitoring device display should be connected to the center tap of the potentiometer, and the other two cables should be connected accordingly. For the other two wires of the potentiometer, gently pull the wires. At this time, the length AD value will increase. If the length AD value decreases, the two wires should be connected in reverse.

3. The adjustment sequence is to adjust to zero first and then to full.

4. Enter the computer length adjustment interface. In the main monitoring interface, press the button to enter the debugging interface. After entering the correct password, enter the length adjustment interface.

4. How to deal with the E12 computer failure of XCMG crane in 07?

XCMG Crane Computer Failure E12: The voltage value of the measurement channel of the rodless cavity oil pressure sensor is lower than the lower limit Reason: The rodless cavity oil pressure sensor is broken and does not support PDB variables of analog values; The electronic component of the measurement channel is broken Solution: Replace For the pressure sensor, set the PDB variable with the correct analog value in DGA6.i.3

5. How to adjust the computer working conditions of XCMG crane?

The pressure regulating valve (relief valve) of the oil pump is generally located next to the pump body in the oil tank, and there are also external ones.

Usually, the pressure regulating valve is adjusted immediately, and there is no need to adjust it repeatedly

6. How to calibrate the computerized weighing of XCMG crane?

The calibration of XCMG crane computer weighing is very important to ensure the accuracy of its weight measurement.

First of all, you need to place the crane flat on a solid ground and check whether all components of the crane are intact before calibration.

Then, calibrate according to the instructions for use of XCMG crane computer weighing, which is usually achieved by adjusting the tension of the wire rope to ensure accurate readings of the crane under different loads.

In addition, electronic weighing instruments need to be checked and calibrated regularly to ensure their accuracy and stability.

Finally, before and after calibration, a zero position test is required, that is, remove all parts of the crane and empty the load, and check whether the reading of the electronic weighing instrument is zero. If necessary, please consult the manufacturer or professional technicians.

7. The computer display length of XCMG crane is wrong?

Fully retract the boom, open the cover of the reel box on the big arm, twist the white gear inside, and adjust it correctly. Coil the threads evenly.

8. Is the brake fault light of XCMG crane always on?

1. Lack of brake fluid: Brake fluid plays a vital role in the car's braking system. When the driver steps on the brake pedal, the force of depressing the pedal is determined by the brake master cylinder. The piston transmits energy through the brake fluid to the brake cylinders located on the wheels, causing the brake pads to contact the wheels to prevent the vehicle from moving forward.

The lack of brake fluid will also be accompanied by an obvious lack of braking power, and in severe cases, the braking power may even be lost. In this case, just replenish the brake fluid in time.

2. The brake switch is damaged: In this case, the brake pedal and the brake sensor switch are not in good contact or the sensor switch is damaged and needs to be disassembled for inspection.

3. Brake pad wear and aging: Brake pad wear and aging may also cause the brake light to stay on. At this time, check the thickness of the brake pad. If the thickness of the brake pad is lower than the specified value, usually 0.8cm, then It is very likely to break during driving and cause danger.

4. In addition to fault factors, it is also possible that the car owner forgot to put down the handbrake, causing the brake indicator light to stay on.

9. Leuchtet die Fehlerleuchte des XCMG 8-Tonnen-Krans?

Der Grund dafür ist, dass der Sauerstoffsensor wahrscheinlich ein Problem hat. Im Allgemeinen können Sauerstoffsensoren drei Jahre oder länger verwendet werden. Sie können an der gelben Motorstörungsleuchte eines Neuwagens prüfen, ob der Stecker des Sauerstoffsensors locker ist.

Ein Grund dafür ist, dass nicht standardmäßige Tankstellen minderwertiges Benzin hinzufügen, was zu einer unzureichenden Vermischung und Verbrennung von Öl und Dampf führt und das Aufleuchten der Fehleranzeige zur Folge hat. Diese Situation hat keinen Einfluss auf die Fahrsicherheit, eine längere Nutzung wird sich jedoch mehr oder weniger negativ auf den Motor auswirken.

Mit Wartungswerkzeugen im 4S-Shop können Sie das Benzin aus dem Kraftstofftank entnehmen und anschließend mit hochwertigem Benzin auffüllen. Aufgrund der heutigen Qualität des Kraftstoffgemischs und der verstopften Stadtstraßen auf dem Markt sind Zündkerzen anfällig für Kohlenstoffablagerungen, was häufig dazu führt, dass der Motor schlecht läuft und daher die Störungsleuchte aufleuchtet. Sie können überprüfen, ob die Zündkerze Kohlenstoffablagerungen aufweist. Wenn ja, entfernen Sie diese mit einer Kupferbürste.
