Excavators are essential machines in construction and heavy-duty earthmoving, known for their versatility and efficiency. A critical component of these machines is their tracks, which provide the necessary traction and stability for various terrains. A common misconception is that steel tracks are brand-specific, meaning that a Caterpillar excavator requires Caterpillar tracks, a Hitachi needs Hitachi tracks, and so on. However, in reality, tracks are more generic, allowing for interchangeability among different brands. This blog delves into the intricacies of steel tracks, focusing on the pitch measurement, common damages, replacement indicators, maintenance tips, and the benefits of considering used tracks from Vikfin before purchasing new ones.
Understanding Track Pitch
What is Track Pitch?
Track pitch is a critical measurement that determines the compatibility of tracks with different excavator brands. It refers to the distance between the center of one track pin to the center of the next pin. This measurement ensures that the track fits snugly around the sprockets and rollers of the excavator's undercarriage, providing smooth operation and optimal performance.
How to Measure Track Pitch
Measuring track pitch is relatively straightforward. Here's a step-by-step guide:
Locate the Track Pin: Identify the pins on the track, which are usually found at the center of each track link.
Measure the Distance: Using a measuring tape, measure the distance from the center of one pin to the center of the next pin.
Record the Measurement: Note the measurement in millimeters (mm).
For most 20-tonne excavators, the standard pitch is 190mm, while 30-tonne machines typically have a 210mm pitch. Understanding these measurements is crucial when sourcing tracks for your excavator, as it ensures compatibility and optimal performance.
