How to install tbm scrapers?

Installing TBM scrapers is a crucial process that requires careful planning, precision, and adherence to safety protocols. As a leading TBM scrapers supplier, we understand the importance of providing clear guidance on the installation process. In this blog, we will walk you through the steps of installing TBM scrapers, ensuring that you can complete the task efficiently and effectively.

Pre - installation Preparation

Before you start the installation of TBM scrapers, it is essential to conduct a thorough pre - installation preparation. This includes gathering all the necessary tools and equipment, as well as inspecting the TBM and the scrapers themselves.

Tool and Equipment Gathering

The tools required for TBM scraper installation typically include wrenches, screwdrivers, lifting equipment, and measuring tools. Make sure that all tools are in good working condition and are the appropriate size for the job. For example, you will need a torque wrench to ensure that the bolts are tightened to the correct specification. Lifting equipment such as cranes or hoists will be necessary to move the heavy scrapers into position.

Inspection of TBM and Scrapers

Inspect the TBM where the scrapers will be installed. Check for any damage, wear, or misalignment on the mounting surface. Any issues should be addressed before proceeding with the installation. At the same time, carefully inspect the TBM scrapers. Look for any signs of damage during transportation, such as cracks or bent parts. You can refer to our TBM Scraper product page for detailed information about the specifications and features of our scrapers.

Installation Steps

Step 1: Positioning the TBM

Ensure that the TBM is in a stable and secure position. If possible, place the TBM on a flat and level surface to prevent any movement during the installation process. This will also make it easier to access the mounting points for the scrapers.

Step 2: Marking the Mounting Points

Use the scraper's mounting template or the manufacturer's instructions to mark the mounting points on the TBM. Make sure the marks are clear and accurate. Double - check the measurements to ensure that the scrapers will be installed in the correct position. This step is crucial for the proper functioning of the scrapers.

Step 3: Mounting the Brackets

If the TBM scrapers come with brackets, install the brackets first. Align the brackets with the marked mounting points on the TBM. Use the appropriate bolts and washers to secure the brackets. Tighten the bolts gradually and evenly to prevent the brackets from warping. Refer to the torque specifications provided by the manufacturer to ensure that the bolts are tightened to the correct level.

Step 4: Installing the Scrapers

Once the brackets are securely installed, it's time to install the TBM scrapers. Lift the scrapers using the lifting equipment and carefully place them onto the brackets. Align the scrapers with the brackets and insert the bolts through the holes. Again, use a torque wrench to tighten the bolts to the specified torque. Different types of TBM scrapers, such as TBM Knife and Single Disc TBM Cutter, may have slightly different installation requirements, so make sure to follow the specific instructions for each type.

Step 5: Alignment and Adjustment

After the scrapers are installed, check their alignment. The scrapers should be parallel to the surface they will be scraping and evenly spaced. Use a straightedge and a level to verify the alignment. If necessary, make adjustments by loosening the bolts slightly and re - positioning the scrapers. Once the alignment is correct, retighten the bolts to the specified torque.

Step 6: Testing

Before putting the TBM back into operation, conduct a test run. Start the TBM at a low speed and observe the performance of the scrapers. Check for any abnormal vibrations, noises, or signs of improper scraping. If any issues are detected, stop the TBM immediately and make the necessary adjustments.

Safety Considerations

Safety is of utmost importance during the installation of TBM scrapers. Here are some key safety tips:

Wear Personal Protective Equipment (PPE): This includes hard hats, safety glasses, gloves, and steel - toed boots. PPE can protect you from potential hazards such as falling objects, flying debris, and sharp edges.
Follow Lifting Safety Procedures: When using lifting equipment, make sure it is properly rated for the weight of the scrapers. Follow the manufacturer's instructions for operating the lifting equipment, and ensure that the load is balanced and secure.
Avoid Working Alone: It is recommended that at least two people are involved in the installation process. This can help in case of an emergency and also make it easier to handle the heavy scrapers.

Maintenance after Installation

Proper maintenance after the installation of TBM scrapers is essential to ensure their long - term performance. Regularly inspect the scrapers for wear and tear. Replace any worn - out parts promptly to prevent further damage to the TBM and the scrapers themselves. Lubricate the moving parts according to the manufacturer's recommendations. Keep the scrapers clean to prevent the accumulation of debris, which can affect their performance.
