The Main Reasons Why A Hydraulic Crane Loses Power

Hydraulic cranes are an important part of many construction projects. They are also very powerful machines that can lift heavy loads. However, hydraulic cranes can lose power and stop working altogether. Discover a few reasons why this might happen.

Hydraulic Fluid Issues

The hydraulic fluid is what allows the crane to move and function. If there is a problem with the hydraulic fluid, it can cause the crane to lose power.

For example, if there's a leak in the hydraulic system, it can cause the crane to lose pressure and power. The fluid works to transfer power from the engine to the hydraulic system. So if there's not enough, there won't be enough power required to operate the crane. Over time, this can lead to the complete failure of the system.

Another problem that can occur is if the hydraulic fluid becomes contaminated. This can happen if dirt or water gets into the system. The contaminated fluid becomes less effective at transferring power or lubricating the system. Oftentimes, this problem can create other issues, such as overheating or hydraulic pump failure.

To prevent hydraulic fluid issues, it's important to regularly check the hydraulic system for leaks. The hydraulic fluid should also be changed according to the manufacturer's recommendations.

Electrical Issues

Most hydraulic cranes rely on electric power to operate. If there is a problem with the electrical system, it can cause the crane to lose power. For example, if the batteries are not charged, the crane will not be able to start or operate.

Additionally, if there is a problem with the wiring, it can cause an electrical short that will trip the breaker and shut off power to the crane. This can happen suddenly without any warning.

However, other electrical issues can occur gradually. For example, if the alternator is not working properly, it can cause the batteries to slowly lose power. The alternator is what charges the batteries while the engine is running.

If it's not working properly, the batteries will lose power until they are completely drained. And while this might not seem like a big deal at first, it can eventually lead to the crane shutting down completely, especially when you need it most.

To prevent electrical issues, it's important to check the batteries and charging system regularly. Additionally, all wiring should be checked for any damage or wear. Any damaged wires should be replaced immediately to ensure that there's no power interruption during operation.

These are just a few of the main reasons hydraulic cranes can lose power. Regularly maintaining your crane and being aware of these issues can help prevent power loss and keep your project on track.
