Hey there! I’m a supplier of second – hand mixer trucks, and today I wanna talk about how to check the hydraulic system of a second – hand mixer truck. This is super important because the hydraulic system is like the heart of a mixer truck. It’s responsible for making the drum rotate and perform all those mixing tasks smoothly. Second Hand Mixer Truck<\/a><\/p>\n

<\/p>\n

First things first, let’s start with a visual inspection. When you’re looking at a second – hand mixer truck, take a good long look at the hydraulic hoses. These hoses are like the veins that carry the hydraulic fluid around the system. Check for any signs of wear, like cracks, cuts, or bulges. If you see any of these issues, it’s a red flag. Cracks can lead to fluid leaks, and bulges might mean that the hose is starting to fail internally. You don’t wanna end up with a hydraulic fluid leak on the road; it’s not only messy but can also cause the system to lose pressure and stop working properly.<\/p>\n

Next, check the hydraulic fluid level. Most mixer trucks have a sight glass or a dipstick to help you with this. The fluid should be at the appropriate level, neither too low nor overfilled. If the fluid is low, it could indicate a leak somewhere in the system. And if it’s overfilled, it can cause excessive pressure and damage the seals. Also, pay attention to the color and clarity of the fluid. Clean hydraulic fluid should be clear and have a consistent color. If it looks dirty, cloudy, or has a strange odor, it might be time to change it. Contaminated fluid can cause wear and tear on the hydraulic components and reduce the efficiency of the system.<\/p>\n

Now, let’s move on to the hydraulic pump. The pump is what creates the pressure needed to move the hydraulic fluid. Start the truck and listen carefully to the pump. A healthy pump should make a smooth, consistent noise. If you hear any rattling, grinding, or whining sounds, it could mean that there’s something wrong inside the pump. Maybe the bearings are worn out, or there’s a blockage in the intake or discharge ports. You can also check the pump’s mounting bolts to make sure they’re tight. Loose bolts can cause the pump to vibrate excessively, which can lead to further damage.<\/p>\n

The hydraulic motor is another crucial part of the system. It’s responsible for converting the hydraulic pressure into mechanical power to rotate the mixer drum. Check the motor for any signs of leaks around the seals. Leaking seals can cause a loss of pressure and reduce the motor’s performance. You can also try rotating the drum by hand (when the engine is off, of course) to see if the motor is free – moving. If it’s hard to turn or there’s a lot of resistance, it could indicate a problem with the motor or the gears inside the drum.<\/p>\n

The control valves are what allow you to operate the hydraulic system. Check to see if the valves are easy to move. They should respond smoothly when you turn the controls. If they’re sticky or hard to move, it could mean that there’s dirt or debris inside the valves, or the valve spools are worn out. Also, check for any signs of leaks around the valve bodies. Leaking valves can cause the system to lose control and make it difficult to operate the mixer drum.<\/p>\n

Another thing to look at is the hydraulic cooler. The cooler is designed to keep the hydraulic fluid at a proper temperature. If the cooler is clogged with dirt or debris, it won’t be able to cool the fluid effectively. This can cause the fluid to overheat, which can damage the seals and other components in the system. You can use a pressure washer or compressed air to clean the cooler fins and make sure there’s good airflow through it.<\/p>\n

Now, let’s talk about the accumulator. The accumulator is like a shock absorber for the hydraulic system. It stores hydraulic energy and helps to smooth out pressure fluctuations. Check the accumulator for any signs of damage, like dents or leaks. You can also use a pressure gauge to check the pre – charge pressure of the accumulator. If the pre – charge pressure is too low or too high, it can affect the performance of the system.<\/p>\n

After you’ve done all these visual and basic checks, it’s a good idea to take the truck for a test drive. During the test drive, pay attention to how the mixer drum operates. Does it start and stop smoothly? Does it rotate at a consistent speed? If you notice any jerks, hesitations, or unusual noises while the drum is rotating, it could indicate a problem with the hydraulic system.<\/p>\n

It’s also important to check the hydraulic system’s documentation if available. The previous owner might have kept records of maintenance, repairs, or any issues they’ve encountered with the system. This can give you valuable insights into the history of the hydraulic system and help you make a more informed decision.<\/p>\n
