Track Pads/Crawler Shoes

Columbia established the use of high strength martensitic steels in crawler shoes. Our track pad/crawler shoe designs offer full support under the roller path to eliminate failures due to collapsing. Additional internal bracing is standard to avoid deformation in the later stages of shoe life.

Product Details

  • All crawler shoes are line bored for accurate pin fit
  • Added structural ribs for improved strength
  • Fully supported roller path
  • Various widths available
  • Alloy steel does not require deformation to harden like manganese steel
  • High tensile strength virtually eliminates pin eye breakage
  • Alloy steel resists stretching
  • H-alloys resist cold-flow, greatly reducing the need to remove metal flow in the roller path
