Our Komatsu Style PC300 Interchangeable Adapters serve as the ultra-stable structural foundation for your 30-ton to 36-ton class heavy excavator fleets. Engineered specifically to accommodate an expansive variety of bucket lip thicknesses (ranging from 3.5cm up to 6.0cm), these two-strap weld-on adapters guarantee a flawless, zero-play lockup with standard Komatsu side-pin bucket teeth. From high-production fleet earthmoving to severe bedrock quarrying, these durable Ground Engaging Tools (G.E.T.) safeguard your bucket's cutting edge while distributing immense hydraulic breakout forces uniformly.
Flawless Fitment & Interchangeability: Tailored precisely to Komatsu OEM blueprints to completely eliminate tip wobble. This preserves adapter nose integrity and prevents horizontal pin shear failure under grueling lateral loads.
Premium Low-Carbon Alloy Casting: Cast using specialized low-carbon metallurgy optimized for field weld-joint reliability. The composition ensures high material fusion with the bucket edge and premium resistance to structural heat-affected zone (HAZ) cracking.
Versatile Lip Gap Selection: Available in highly precise gap variants from 35mm to 60mm, allowing fleet operators to match reinforced or custom-plated bucket lips perfectly without modifying the original bucket edge profile.
Through-Hardened Structural Strength: Advanced multi-stage heat treatment yields exceptional internal core toughness and optimized surface hardness, resisting elongation and permanent nose deformation during maximum breakout prying.

Reinforced Dual-Strap Profile: The specialized double-strap profile wraps securely around both the upper and lower edges of the bucket lip, stabilizing the entire assembly against intense torsional and bending forces encountered in shot-rock handling.
Hydrodynamic Taper Design: Smooth exterior transition boundaries significantly lower material build-up and drag resistance during bucket filling cycles, maximizing penetration efficiency and optimizing fuel consumption.
Integrated Corner Protection System: Fully compatible with heavy corner adapters like the 207-934-7181 to supply total bucket wing armor and crisp side-cutting performance for long-reach ditch cleaning and sloping tasks.
