Our Komatsu PC300 Interchangeable Series Rock Ripper (also known as a frost ripper or ripper shank) is a severe-duty attachment engineered to fracture the most unyielding strata. Professionally optimized for 30-ton to 36-ton class heavy-duty hydraulic excavators—including the Komatsu PC300, PC300LC, PC350, and PC360—this single-shank ripper is deployed where standard rock buckets fail. By concentrating the machine's entire hydraulic breakout force onto a single pinpoint tip, it effortlessly pre-fractures hardpan, frozen ground, caliche, shale, and blasted granite to streamline downstream digging and loading cycles.
Monoblock High-Strength Mainboard: Cut from a solid, ultra-thick slab of premium NM400 / Q355B high-tensile alloy steel. The single-piece shank design completely eliminates structural weld fatigue lines under severe lateral bending stresses.
Streamlined Arc-Taper Profile: The mathematically calculated arc geometry maximizes digging penetration angles. This specific curvature allows the shank to glide smoothly into hard strata, minimizing machine hydraulic back-pressure and reducing fuel consumption.
Premium Hardox Face-Shield Protection: The front leading edge of the shank is armored with a replaceable, highly abrasive-resistant NM500 / Hardox wear shroud, shielding the structural mainboard from continuous friction-thinning.
Komatsu OEM G.E.T. Alignment: Pre-fitted with a standard Komatsu-style 207-939-5120 adapter base and an ultra-sharp 207-70-14151TL Tiger tooth, providing unmatched piercing capabilities and zero-play component lockups.
