Crawler crane undercarriage is an important part of construction machinery, which is vital to ensure the normal operation and prolong the service life of mechanical equipment. In this article, we will share some practical maintenance advice and tips to help you solve common faults of crawler crane undercarriage and learn how to perform effective maintenance.

1. Common faults and solutions of crawler crane undercarriage:

  a. Loose or slippery tracks: Loose or slippery tracks may cause the undercarriage not to travel properly. Check the track tensioner to make sure it is properly adjusted. Adjustments can be made according to the equipment manual if needed.

  b. Worn or Broken Tracks: Worn or broken tracks may reduce the travel performance of the undercarriage. Regularly check the wear of the tracks and replace them or repair them if they are found to be badly worn.

  c. Track Sprocket Failure: Failure of the track sprocket may cause the chain to loosen or break. Check the sprockets for wear and looseness and repair and replace as necessary.

  d. Hydraulic System Failure: Failure of the hydraulic system may result in the undercarriage not functioning properly. Regularly check the quality and pressure of the hydraulic fluid and make sure there are no leaks in the system. If problems are found, clean or replace the hydraulic fluid and check hydraulic connections for tightness.

2. Maintenance suggestions and tips:

  a. Regular Inspection and Cleaning: Regularly inspect all parts of the undercarriage and clean them of impurities and accumulated dust. This helps to minimize wear and tear and prolongs the life of the undercarriage.

  b. Maintain Lubrication: Lubrication is key to maintaining the undercarriage. Regularly lubricate lubrication points according to the instructions in the equipment owner's manual. Ensure that the proper lubricant is used and that the correct lubrication method is used.

  c. Pay attention to the working environment: Avoid using the undercarriage in harsh working environments, such as muddy areas or excessively dusty environments. These environments can accelerate wear and failure. If it is necessary to work in these environments, add protective measures and increase maintenance.

  d. Regular Maintenance and Overhaul: In addition to regular routine inspections and cleaning, regular comprehensive maintenance and overhaul should be performed. This includes replacing lubricants, filters and other wear parts, as well as making system adjustments and tightening connections.
