Columbia Steel pioneered the use
of high strength martensitic steels
for crawler shoes.
Alloy choice combined with engineered design improvements make Columbia Steel's crawler shoes reliable and long-lasting.

Design of Crawler Shoes.
Columbia product engineers make design improvements which result in stronger crawler shoes. Columbia's designs offer full support under the roller path to eliminate roller path failures due to collapsing. Additional internal bracing is standard to avoid deformation in the later stages of shoe life.

|
• All crawler shoes are line bored for accurate pin fit
• Added structural ribs for improved strength
• Fully supported roller path
• Various widths

Metallurgy of Crawler Shoes.
Columbia established the use of high strength martensitic steels in crawler shoes. Our H-series alloys offer numerous benefits, including:
|
|
• Alloy steel does not require deformation to harden like manganese steel. Alloy steel possesses good hardness from
the very beginning.
• High tensile strength virtually eliminates pin eye breakage.
• Alloy steel resists stretching.
This reduces the need for track adjustment and holds the proper pitch, extending pad and tumbler life.
• H-alloys resist cold-flow, greatly reducing the need to remove metal flow in the roller path.
Contact Columbia Steel today and get the high strength steel alloy advantage.
