How to Maintain the Hydraulic Cylinder of Dump Truck

For truck drivers, the dump truck is not only a tool to make money, but also a reliable partner. The invention of the hydraulic cylinder as a part of the installation on the dump truck has provided convenience for many engineering operations. Each type of hydraulic cylinder has a suitable field positioning, which we have explained in detail in the article What Are the Classifications of Common Hydraulic Cylinders for Dump Trucks.
 
In daily use, the protection and maintenance of hydraulic cylinders are particularly important for truck drivers. The operating conditions of dump trucks are different from other vehicles. Generally, dump trucks are used for relatively poor road conditions and large load capacity, so whether it is a front-mounted hydraulic cylinder, a mid-mounted hydraulic cylinder or a rollover hydraulic cylinder, all require our careful maintenance to make their service life longer.
 
In fact, the most important part of the hydraulic system is the hydraulic oil. The hydraulic oil is divided into 32# and 46#. In winter, it is generally better to use 32# hydraulic oil with a lower viscosity, and in summer, we can use 46# hydraulic oil with high consistency. It should be noted that it is strictly forbidden to mix hydraulic oils of different brands and labels.
 
The cleanliness of the oil in the hydraulic system is very important. The cleanliness of the oil and the replacement cycle must be guaranteed. If impurities are mixed into the hydraulic oil, it will enter the valve group and the oil cylinder with the hydraulic pipe, causing the valve group to be stuck or damage the sealing ring of the oil cylinder. At the same time, check the hydraulic pipeline regularly to check whether there are cracks or leakage at the interface, so that the fault can be found in time and the damaged parts can be replaced in time. Why should we do these? Because the hydraulic oil pressure increases sharply when the hydraulic cylinder is lifted, the pipeline will not hold up and burst. .
 


Many dump trucks transporting sand and gravel are equipped with a protective cover to the casing of the hydraulic cylinder to prevent impurities from entering the oil. At the same time, pay attention to whether there is abnormal wear and scratches on the surface of the hydraulic piston rod. If there is any, it needs to be repaired, corrected or replaced by the professional repair department, otherwise it will affect the lifting efficiency and safety.
 
The general hydraulic cylinder has a long service life and a low failure rate. Drivers just need to pay attention to the smoothness of the road surface when unloading the truck. If the inclination angle is too large, do not force the hydraulic cylinder to dump. You need to observe whether the lock of the rear tail plate of the cargo box is opened or not, to prevent cargo from accumulating inside the cargo box after the hydraulic cylinder is lifted. It is very common in the field of construction trucks.
 
After all the cargo is put down, the driver needs to confirm the safety before setting off. Many drivers make low-level mistakes that they will drive away in a hurry before all cargo is unloaded, which may cause accidents. 
 


After years of development, the structure of the hydraulic cylinder has become relatively mature, but there are still dump trucks that have accidents due to the failure of the hydraulic cylinder. When choosing a hydraulic cylinder, it is also recommended to choose a product with a famous brand and a high reputation. The reliability and later maintenance will be guaranteed. At the same time, according to your own operating conditions and load capacity, you should choose a hydraulic cylinder that suits you.
 
If you choose any second-hand dump trucks for sale from Talenet, we will replace your truck with a new hydraulic cylinder during the refurbishment process, so there is no need to worry about the problem of the hydraulic cylinder.
