The dump bucket of the dump truck can t be raised, what is the problem 5

If the hydraulic fluid is sufficient, check the gear pump again.

Whether it is broken or not, depends on the pressure, if there is pressure, it is not a coupling.

Broken, listen to the sound, listen to the jacking cylinder.

There is no sound, if there is a change in the cylinder seal, and then see if the reversing valve and the relief valve are broken.

Dump truck hydraulics.

Daily check-ups:

Daily inspection of the vehicle before starting.

Vehicle in-operation monitoring.

Keep the hydraulic oil of the dump truck clean (check the cleaning of the oil and check the oil level at the same time) The precautions are as follows:

Do not accumulate rain and dust in the oil filling drum, and do not place it directly on the ground;

When wiping pumps, valves or containers filled with oil, it is necessary to prevent cloth debris and debris from falling into the oil;

The oil tank should be cleaned frequently, and the oil should pass through a filter of more than 120 mesh when the oil is tanked.

It's better to say what car, how big is the car, what hydraulics, the front roof? Mid-top? Twin cylinders?

If you can't lift it, first look at whether the chassis power take-off is running the hydraulic pump and whether it is oiled, see if the hydraulic oil is enough, then see whether the control valve and hydraulic valve are working normally, then see if the oil circuit and gas circuit are leaking, and finally see if there is a problem with the hydraulic cylinder.

Once you've done that, it's pretty much solved.

The dispenser lever is not placed in the neutral position. As a result, the lifting is oiled back and cannot be lifted normally. If there is oil return, it cannot rise normally.

The power take-off of the oil is good, but the linkage shaft does not rotate.

Hydraulic oil, look at the less? If not, take a look at the hydraulic pump. Let's take a look at whether you're hanging up and taking strength.。。

If you want to stop when the dump truck is starting the bucket, you can push the anti-bucket gear lever forward, push it to the first position is to stop, and push it to the front position is to fall back, the specific operation steps are as follows:

1. Open the driver's door.

2. Press the brake pedal.

3. Twist the car key to start the vehicle.

4. Move the bucket switch backwards to start the bucket.

5. Push the bucket switch to the middle to stop the bucket.

Pull on the handbrake Step on the clutch and open the power take-off, according to the car you drive, select the corresponding gear (generally 3-4 gears), and then open the lift valve switch (don't say you don't even know where the valve switch is), slowly release the clutch, at this time the car box will slowly rise (note that the throttle is controlled within 1,500 rpm), when the cargo is halfway down, depending on the situation, release the handbrake, at this time, step on the clutch, turn off the power take-off, go forward a little bit, pull the handbrake, and then repeat the operation for the first time. Turn off the power take-off when you fall into the bucket, (if the gear is not taken off, you have to step on the clutch and turn it off) and then move the lifting valve to the lower position.

Summary. The power take-off is a set of variable speed gears, which are connected to the gearbox using a gear connection with the lifting pump shaft. The power take-off has a separate gear in the gearbox, and when this gear is hooked, the lift pump can be operated after the throttle is refueled.

Hello, I'm glad to answer you Ziqin I have seen your question, Qiao quietly I am helping you inquire about the relevant information, please wait for Ma Xiao's book to reply to you. 

1.If the pressure is not enough, check the regulator. 2.The oil pump is worn. 3.Check the hydraulic fluid for deterioration. 4.The cylinder seals are damaged.

That's the problem.

You can check it out.

When the power take-off is hung up, the sound of oil cannot be heard.

The oil pump will have a sound after it starts, if there is no sound, it means that it is not started.

Or if there is no pump oil, you can't get on the car without oil, and there is no sound.

In the past, when I hung up the power take-off gearbox, I could feel it turn out, but now it doesn't turn, which is the best problem?

The power take-off is a set of variable speed gears, which are connected to the gearbox using a gear connection with the lifting pump shaft. The power take-off has a separate old Zen partner in the gearbox, and when this gear is hung up, the lift pump can be operated after the gas pedal.

If the transmission is not running, it is possible that the gears are broken, or there is a problem with the connection position.

You mean it's possible that the power take-off is broken, right?

Not exactly, it could also be a gear issue.

will cause a situation where it does not work.

Is it also possible that the gearbox is broken? If the gearbox is broken, the car will be in gear.

The variable box has the gears of the lift pump, and if that one is destroyed, it will not be able to fight.

So what if I check ** first in this case?

Generally, there are fewer problems with the variable, so check the power take-off first.

Okay, thank you, big brother!

You are welcome. If you are satisfied with me, please give me a 5 star like

Hello, the dump truck does not give oil to the dump bucket this situation is because of the hydraulic control valve, the second is, the hydraulic cylinder of the question, the internal oil leakage. First of all, you must ensure that there is enough in your hydraulic oil tank, like yours, you need to check whether the control valve is damaged as soon as possible, resulting in the inability to apply normally, and check whether the hydraulic oil in the cylinder is leaking, and whether the oil seal seal is not tightly sealed.

Summary. Hello, I'm glad to answer for you: what is the matter with the dump truck turning one wheel and one wheel not turning, the above wheel turning and not turning is the role of the differential, which is a normal phenomenon.

The differential design is because when the car is cornering, the speed of the inner and outer wheels is different, if it is just connected, the number of rotations of the inner wheels is small, and the number of rotations of the outer wheels is large, which will produce slippage and affect the handling of the car.

Hello, I'm glad to answer for you: what is the matter with the dump truck turning a wheel and not turning, grinding or rotting a round of holes and turning a wheel without turning is the role of the differential, and it is normal to miss a blind leakage. The differential design is because when the car is cornering, the speed of the inner and outer wheels is different, if it is just connected, the number of rotations of the inner wheels is small, and the number of rotations of the outer wheels is large, which will produce slippage and affect the handling of the car.

With the addition of a differential, the power is distributed freely between the two wheels, which balances the speed of the inner and outer wheels, allowing the outer wheels to rotate more times and help the car smooth cornering. Also due to the existence of the differential, after one side of the driving wheel is suspended, because the power is distributed by the differential speeder, one side of the wheel has resistance, and the other side does not, and the power is all distributed to the wheel without resistance (that is, the suspended one), so you can see that the wheel that hits the ground does not move (there is no leakage and the power is distributed), and the suspended wheel rotates wildly. Return to the bush.

I have a dump truck, the other parts are normal, the left does not turn when driving, what is the right turn?

In the two driving half shafts, there is a device called a differential, and there is a cross shaft inside, and four planetary gears are sleeved on the shafts, and one end of the two driving half shafts is meshed with these four gears respectively. When one side of the half shaft encounters a large resistance, the planetary gear that is meshed with it will rotate, so that the speed of the half shaft will be reduced, and the other side of the half shaft is still rotating at the original speed, which plays a differential role, so the above-mentioned round of laughing cherry blossom rotation is the effect of the differential hitting the travel plexus, which is a normal phenomenon.

Press the clutch, turn on the power take-off, release the clutch, and turn on the lift bucket switch. Select the lifting speed according to the type of cargo. It is strictly forbidden to lift to the top at one time.

When the goods are not unloaded, slow down, drop the barrel quickly, drop the barrel, step on the clutch, close the power take-off, release the clutch, start after the hail, and drive away. But it's important to turn off the power take-off first and start in seven steps, otherwise the hydraulic fluid will come out.

Rear eight-wheel dumping operation method:

1.The power take-off is engaged to provide hydraulic oil output to a rotary gear pump;

2.The manual valve controls the air path so that the pneumatic reversing valve is raised from the middle parking position to the lifting position, and the hydraulic oil is entered into the lower cavity of the cylinder to lift and start unloading. After reaching the limit height, the goods are unloaded, and the gas path of the limit valve is triggered, so that the reversing valve returns to the middle parking position;

3.The manual valve is moved to the lowering station, and the hydraulic oil in the lower chamber of the cylinder is returned to the oil tank to make the cylinder lower, which has two forms: rapid descent and slow descent. Generally, the rear eight wheels have a climbing gear, called a turtle gear.

The dump truck should be unloaded on a flat ground and on the old noisy side, otherwise it is easy to overturn. Comparatively speaking, the middle hydraulic jack is more likely to roll over than the front hydraulic jack.

Step on the clutch, open the power take-off, loosen the clutch, open the lifting bucket switch, according to the type of goods, select the lifting speed, and it is forbidden to rise to the top at one time. The goods are not unloaded with slow dropping, the empty bucket is used to descend quickly, the bucket is lowered, the clutch is stepped on, the power take-off is closed, the clutch is loosened, and finally the start is driven away. However, it should be noted that the stove is not disturbed to turn off the power take-off first, and set off in seven steps, otherwise the hydraulic oil will spray out.

After the eight-wheel dump operation method:

1.The power take-off engages to rotate the gear pump to provide hydraulic oil output;

2.The manual control valve controls the air circuit so that the pneumatic control reversing valve is from the middle stop station to the lifting station, and the hydraulic oil is entered into the lower cavity of the cylinder to realize the lifting and unloading, and the goods are unloaded after reaching the limit height, and the gas path of the limit valve is opened, so that the reversing valve returns to the middle stop station;

3.The manual control valve is moved to the lowering station, and the hydraulic oil in the lower chamber of the cylinder returns to the oil tank to make the cylinder lower, which has two forms: fast descent and slow descent. The rear eight wheels generally have a climbing gear, called the turtle gear, the dump truck unloading should be unloaded in a flat place, otherwise it is easy to roll over, relatively speaking, the hydraulic top is easier to roll over than the front top hydraulic.
