Knowledge about Hydraulic Oil for Truck-Mounted Cranes Tow Crane

The operation of the crane on a kamioian muntatutako garabia is dependent on hydraulic cylinders, which results in a significant consumption of hydraulic oil. Have you got a clear understanding of when and how to replace the hydraulic oil? If you’re still in the dark or not entirely sure about it, fellow kamioian muntatutako garabia users, let’s explore this together.

The determination of whether the hydraulic oil for a kamioian muntatutako garabia needs to be replaced can be based on the identification of its viscosity. Here are two effective methods for this purpose:

The first method is the inverted hydraulic oil in containers. Take out the hydraulic oil from the hydraulic tank and also obtain standard hydraulic oil. Then, pour them respectively into two transparent glass bottles of the exact same size and cap both bottles securely. Position these two bottles adjacent to each other and turn them upside down. If the bubbles in the tested hydraulic oil ascend more rapidly within the bottle compared to those in the standard hydraulic oil bottle, it’s an indication that the viscosity of the tested hydraulic oil is lower than that of the standard one. On the contrary, if the bubbles rise more slowly, it implies a higher viscosity. However, if the bubbles in both bottles rise at approximately the same speed, it suggests that the viscosities are comparable, and no dilution is necessary.

The second approach is the tilted glass plate method. Procure a clean glass plate and position it horizontally. Deposit a drop of the extracted hydraulic oil onto the glass and simultaneously place a drop of the standard hydraulic oil right beside it. Now, tilt the glass plate and closely observe the flow rate and the distance the oil travels. If both the flow rate and the travel distance of the tested hydraulic oil are greater than those of the standard hydraulic oil, it indicates that its viscosity is lower than the standard fluid. Conversely, if they are smaller, it means the viscosity is higher.

It’s important to note that typically, the hydraulic oil of a kamioian muntatutako garabia requires replacement after two to three years of usage. Theoretically, the criteria for changing the oil hinge on factors such as the viscosity and aging degree of the oil, as well as its cleanliness. In the practicalities of daily work, the decision can be made based on the actual working conditions and accumulated experience.

Now, let’s delve into the process of how to replace the hydraulic oil:

Firstly, it’s essential to drain all the hydraulic oil from the hydraulic tank. After that, thoroughly clean the tank to remove any residue or contaminants. Once clean, introduce new hydraulic oil into the tank.

The next step involves removing the main circuit and starting the engine, allowing it to idle. This action enables the oil pump to operate.

Subsequently, manipulate each mechanism separately. The hydraulic oil will facilitate the expulsion of the old oil within the circuit one by one. Continue this process until fresh oil starts flowing from the return manifold.

Finally, reconnect the return manifold to the tank and replenish the tank with new hydraulic oil up to the specified level. Although this method of oil change might be somewhat time-consuming, it ensures an excellent outcome.

Regular replacement of hydraulic oil is crucial for the smooth and efficient operation of the kamioian muntatutako garabia. It helps maintain the performance and longevity of the hydraulic system, reducing the risk of breakdowns and ensuring the crane functions optimally when in use.

By adhering to these guidelines and conducting timely and proper hydraulic oil changes, kamioian muntatutako garabia operators can enhance the reliability and productivity of their equipment, minimizing downtime and maximizing operational efficiency.

Bukatzeko, having a comprehensive understanding of when and how to replace the hydraulic oil is an integral part of maintaining the health and functionality of a kamioian muntatutako garabia. It not only prolongs the life of the equipment but also contributes to safer and more effective operations in various working scenarios.
