Track shoes, or called as cleats or track pads, are fabricated with high tension steel, which makes it less prone to cracking or being bent due to the wider spread between yield strength and ultimate tensile strength. Track pad steel tensile strength reaches 620Mpa. Customer could select much harder steels, whose tensile strength could reach 860Mpa. Track shoes are box-shaped, welded or bolted to the chains and fully covering the pontoons. UHMW wear plate or HDPE or HDMP plate, is the optional design to meet the challenge of wearing when machine often moves on stiff or tough ground. Usually there are two Ultra High Molecular Weight track wear pads per cleat.
