The TG216M Triple Grouser Track Shoe is the standard OEM-spec replacement for Komatsu PC300 and PC350 series excavators — the workhorses of construction sites worldwide. With a 216mm pitch, 600mm width, and triple grouser configuration, this shoe delivers the proven performance that PC300 operators depend on. Forged from 25MnB boron alloy steel and processed through a complete heat treatment cycle, each shoe achieves HRC 42-46 on all three grouser surfaces for consistent, long-lasting wear performance. CNC machining ensures precise bolt hole positioning for fast, trouble-free track chain assembly. The black anti-corrosion coating protects during storage and sea transport.

• PC300 Class Standard: Most common track shoe specification for Komatsu PC300-6, PC300-7 excavators — proven 216mm pitch design
• TG Triple Grouser Configuration: Industry-standard triple grouser pattern for excavator applications with balanced traction and flotation
• 600mm Standard Width: Factory-recommended width for PC300 providing optimal ground pressure and stability
• Forged 25MnB with Full Heat Treat: Complete austenitizing, quenching, tempering cycle with induction hardening on all grouser surfaces

Our manufacturing facility spans over 20,000 square meters equipped with advanced forging production lines, CNC machining centers, and automated heat treatment furnaces. We operate 8 die forging hammers (1T-10T capacity), 12 CNC turning/milling machines, and 4 continuous mesh-belt quenching & tempering furnaces with precise temperature control. Annual production capacity exceeds 500,000 track shoes. Every batch undergoes rigorous quality inspection including dimensional gauging, hardness testing (HRC), ultrasonic flaw detection, and magnetic particle inspection. We hold ISO 9001:2015 and ISO 14001:2015 certifications, with SGS/Bureau Veritas third-party inspection available upon request. Our in-house metallurgical lab ensures consistent 23MnB/25MnB boron steel composition and optimal heat treatment parameters for maximum wear resistance and impact toughness.
