As a supplier of HOWO Mounted Straight Boom Cranes, I understand the importance of maintaining and replacing worn-out parts to ensure the optimal performance and safety of these powerful machines. In this blog post, I will share a detailed guide on how to replace the worn-out parts of HOWO Mounted Straight Boom Cranes.
Step 1: Identify the Worn-Out Parts
The first step in replacing worn-out parts is to conduct a thorough inspection of the crane. Look for signs of wear and tear such as cracks, excessive rust, or loose connections. Pay close attention to critical components like the boom, hydraulic cylinders, pulleys, and cables. These parts are often subject to high stress and are more likely to wear out over time.
Here are some common signs that a part may need replacement:
- Unusual noises during operation, such as grinding or squeaking, can indicate worn bearings or gears.
- Leaking hydraulic fluid is a clear sign of a problem with the hydraulic system, which may require the replacement of seals or hoses.
- Visible damage to the boom, such as dents or bends, can compromise its structural integrity and should be addressed immediately.
Step 2: Gather the Necessary Tools and Parts
Once you have identified the worn-out parts, you need to gather the appropriate tools and replacement parts. Make sure you have the correct size and type of parts for your HOWO Mounted Straight Boom Crane. You can source these parts from authorized dealers or directly from the manufacturer.
Some of the essential tools you may need include:
- Wrenches and sockets of various sizes for removing and installing bolts.
- Hydraulic jacks and stands to support the crane during the replacement process.
- A torque wrench to ensure that bolts are tightened to the correct specifications.
- A crane scale to check the weight capacity of the crane after the replacement.
Step 3: Prepare the Crane for Maintenance
Before starting the replacement process, it is crucial to prepare the crane for maintenance. This involves ensuring the crane is parked on a level surface and the engine is turned off. Engage the parking brake and chock the wheels to prevent the crane from moving.
If the replacement involves working on the hydraulic system, you need to relieve the pressure in the system. This can be done by following the manufacturer's instructions for bleeding the hydraulic lines.
Step 4: Remove the Worn-Out Parts
With the crane prepared, you can now start removing the worn-out parts. Use the appropriate tools to loosen and remove the bolts or fasteners holding the part in place. Be careful not to damage any surrounding components during the removal process.
For example, if you are replacing a hydraulic cylinder, you may need to disconnect the hydraulic hoses. Make sure to label the hoses correctly to ensure proper reinstallation.
Step 5: Install the New Parts
Once the worn-out parts have been removed, it is time to install the new ones. Follow the manufacturer's instructions carefully to ensure the correct installation of the parts. Make sure all bolts are tightened to the specified torque settings to prevent any loosening during operation.
When installing hydraulic components, it is essential to use the correct seals and gaskets to prevent leaks. Lubricate the seals with hydraulic fluid before installation to ensure a proper fit.
Step 6: Test the Crane
After the new parts have been installed, it is crucial to test the crane to ensure everything is working correctly. Start the engine and operate the crane through its full range of motion. Check for any unusual noises, vibrations, or leaks.
Use a crane scale to verify the weight capacity of the crane. Make sure the crane can lift the specified load without any issues. If you notice any problems during the test, stop the operation immediately and investigate the cause.
Step 7: Regular Maintenance and Inspection
Replacing worn-out parts is just one aspect of maintaining a HOWO Mounted Straight Boom Crane. Regular maintenance and inspection are essential to keep the crane in good working condition and prevent future problems.
Establish a maintenance schedule and follow it diligently. This should include tasks such as lubricating moving parts, checking the hydraulic fluid level, and inspecting the cables and pulleys for wear.
In addition to regular maintenance, it is also important to conduct periodic inspections by a qualified technician. They can perform more in-depth inspections and identify any potential problems before they become serious.

Replacing the worn-out parts of a HOWO Mounted Straight Boom Crane is a critical task that requires careful planning and execution. By following the steps outlined in this guide, you can ensure the safe and efficient operation of your crane.
