Is The Track Plate of A Rotary Drilling Rig A Vulnerable Part? Second-hand Track Plate Selection Guide

The track plate of the rotary drilling rig directly contacts the ground, bears the weight of the entire machine and enables movement. Due to long-term friction and impact, it is indeed a vulnerable part. When choosing second-hand track plates, key points need to be mastered. The following is a practical guide.

1. Wear degree assessment: Check the depth of the pattern on the surface of the track plate. If the wear is uniform and the remaining depth reaches more than 1/3 of the original size, it can still be used normally. Excessive thinning of the edges requires caution.

2. Structural integrity inspection: Check whether the plate body has cracks or deformations, and whether the connection holes are worn or cracked. Fine cracks can be repaired, but severe deformation will affect the stability of walking.

3. Material hardness testing: Measured by a hardness tester, the hardness of high-quality track plates should meet the standard. If it is too low, they are prone to wear; if it is too high, they may break due to brittleness.

4. Connection component status: Check the track pins, bushings, etc. If they are overly loose or worn, it will cause abnormal noises during movement and affect the service life.

5. Adaptation to the usage environment: Based on the working site, such as muddy or rocky areas, select track plates with corresponding patterns and strengths to prevent premature damage.

6. Cost-performance consideration: Compare the remaining lifespan and price of second-hand track plates, and combine maintenance costs to select products with a high overall cost-performance ratio.

When purchasing second-hand rotary drilling rig track plates, a comprehensive assessment of wear, material, connecting parts and other conditions is necessary. Only by combining the usage environment and cost performance can suitable accessories be selected to ensure the efficient operation of the equipment.
