Why can t the forklift steering wheel move when the car is cold in winter, and the car is good for m

It is because of the thick hydraulic oil, even if the low-grade hydraulic oil is replaced, it can only be slightly better, and it is recommended to warm up the truck for about 20 minutes before using the forklift in winter.

In winter, the temperature is low and the concentration of hydraulic oil is high, which leads to poor directional assistance, and it is normal after a little warm-up. It is possible to change the hydraulic oil with a high grade.

Forklifts are generally hydraulic power steering, which should be caused by low temperature in winter, high oil viscosity, and abnormal working of the steering gear.

You can see if it is a problem with the steering gear, if not consider changing the hydraulic oil with low viscosity.

If the hydraulic oil is too thick, you can change the No. 32 hydraulic oil.

1.See if the lifting is normal, if it is normal, it may be the diverter valve, and the oil seal of the steering cylinder is broken.

2.If lifting is not possible, it may be that the hydraulic pump is damaged or the oil inlet pipe and strainer are blocked. Hydraulic fluid is not enough.

Cause of the fault and how to troubleshoot it.

When the forklift is operating, the oil leakage at the return pipe of the lifting cylinder is serious and automatically lowers the fault diagnosis: due to the damage of the oil seal between the lifting cylinder and the piston rod. Troubleshooting:

Replacing the oil seal can be eliminated, but during the installation process, the oil seal is often damaged because the installer cannot master the installation methods and skills. It is recommended to make a fixed ring of live hard iron sheet to cover the oil seal during installation, and clamp the live mouth with pliers and send it into the cylinder barrel, so as to avoid the waste caused by oil seal damage, and the live iron ring can be used repeatedly to save and reduce consumption.

When the forklift is operating, the piston rod of the left and right lifting cylinders is not synchronized with the fault diagnosis: the nylon guide sleeve between the lifting cylinder and the piston rod is expanded. Troubleshooting:

During installation, the nylon guide sleeve should be properly adjusted, and the nylon guide sleeve should be sawed off by 3mm with a hacksaw, so that it has a certain opening gap to ensure the expansion coefficient, so as not to cause the above failures in the process of use.

When the forklift is operating, there is no lifting and no direction fault diagnosis: insufficient hydraulic oil, dirt in hydraulic oil, and rupture of hydraulic oil filter. Troubleshooting:

When the hydraulic oil is insufficient or the hydraulic oil is dirty, replace the hydraulic oil with a new one and add it to the specified position. When the hydraulic oil filter is broken, replace the new filter in time.

The above method systematically expounds the basic solution to the failure, and more importantly, since the above problems have occurred, it means that the hydraulic system is blocked, and it cannot be fundamentally solved by changing the new hydraulic oil. It is recommended to disassemble, clean and dredge the multi-way reversing valve to fundamentally solve the above faults.

4.When the forklift is operating, the steering wheel is not sensitive when turning the steering wheelFault diagnosis: the steering gear positioning reed is broken, and the steering cylinder is leaking.

Troubleshooting: If you turn the direction in situ and feel that the direction is too light, it can be determined that the steering reed is broken, and it can be solved by replacing the steering reed. If you feel that there is a certain sense of force when turning the steering wheel and the steering wheel is very insensitive, and the steering wheel can rotate 360 degrees when turning the steering wheel to the left or right, it can be determined that the oil seal on the piston in the steering cylinder is damaged, resulting in internal leakage, and the fault can be eliminated by replacing the oil seal.

5.When the forklift is operating, the piston rod of the lifting cylinder is shakenFault diagnosis: the first judgment is that the hydraulic oil in the oil tank is insufficient, resulting in insufficient pressure of the oil pump. The secondary judgment is that there is air in the piston section from the hydraulic pipeline to the cylinder.

Troubleshooting: If adding hydraulic oil does not solve the problem, it is necessary to loosen the return pipe of the lifting cylinder, and lift the cylinder to the top and then fall to the bottom, and repeat the operation and lift several times to discharge the air in the hydraulic pipeline, this troubleshooting.

Summary. Hello, whether the forklift direction is not played is generally a failure caused by the lack of direction booster oil or the failure of the steering machine. It is recommended to check whether there is less directional booster oil first, and if it is missing, find the location of the oil leak for maintenance.

These are no less, and the steering machine has changed.

The oil seal of the steering engine cylinder was also changed.

The oil pump is not good or the hydraulic oil is not good, otherwise there is a problem with the steering machine. The small hole in the divider valve is blocked, you can try to remove it and pass it.

gear to see if there is a problem.

Good good. Good.

Where is the diverter valve located.

Hello, under the cab, there is a control valve that can be twisted is the diverter valve, also known as the speed synchronisation valve.

1. Diesel forklift: The forklift has been used for several years, and the new forklift is oversteered, and there is a limit screw at each end of the rear axle, just adjust it. If the forklift has been used for a long time, it may be a hydraulic problem, the pressure of the multi-way valve is not enough to rotate, and the hydraulic pump is seriously worn and cannot provide enough pressure.

There is also a possibility of leakage in the steering machine, resulting in insufficient pressure.

2. If the words of electric forklifts are not good, each brand has its own steering method, which requires a specific brand.

Let's see if there is a problem with the gear pump, if the lifting is normal, it has nothing to do with the multi-way i valve!

The transverse cylinder you mentioned didn't leak oil. Instructions are no problem!

So now there are only two places that could be broken!

One is the gear pump, and the other is the steering machine. I also want to ask if it can't be moved in place or is it also heavy in the direction of driving?

If the other cylinders are working properly and just the direction is not good, I recommend looking at the steering knuckle (something like an oil pot under the steering wheel, the size of a cup).

If the multi-way valve is replaced or the problem is still the problem, then it may be that the diverter valve is broken.

Check the steering machine, and if there is no problem, check the steering assistance.

The forklift has been used for a few years, and the steering suddenly can't be moved

Sometimes you move on the spot, sometimes you don't.

Increase the throttle and step on the car to see if it works

There is a greater possibility of damage to the steering machine.

Summary. Hello, I am happy to answer your car master exclusive technician to answer your car questions sincerely and sincerely for you, and find solutions and methods for you to ask questions. The direction of the forklift is controlled by hydraulic pressure, and it may not be possible to move in the morning, it may be caused by the hydraulic oil being too sticky or the filter element is blocked, you can first replace the hydraulic oil and replace the filter element, if it still doesn't work, check whether the hydraulic pump is damaged.

Hope mine is helpful to you.

The forklift lifts normally in winter, and the direction can't be moved in the morning.

Dear, this question is up to me, it takes a little time to type, please be patient, thank you!

Hello, I am glad to answer your car master exclusive technician attentively, attentively and sincerely answer your car questions, and find solutions and methods for you to ask questions. The direction of the forklift is controlled by hydraulic pressure, and if there is no movement in the morning, it may be caused by the hydraulic oil being too sticky or the filter element is blocked. I hope my Lu Zhao will be helpful to you.

Hello, the direction can't be moved, 1 is the direction oil pump on the torque converter is broken; 2. The small hole in the body of the diverter valve is blocked under the multi-way valve. Tear it down and get it through. The forward or backward reaction is slow, and the 1 hydraulic transmission oil filter is blocked.

2. The oil is too dirty, and the friction plates in the 3 gearbox are broken. The impeller in the torque converter is stuck in the middle and quietly, and it does not turn the hole. I hope mine can help you, I wish you a happy life, thank you for selling scum.
