Cat LC Series (Twin Tiger Long) — Premier Choice for Extreme Penetration

Cat® LC Series (Twin Tiger Long) — Premier Choice for Extreme Penetration

The LC Series (Twin Tiger Long) bucket teeth are the premier choice for extreme penetration in the most challenging environments, including frozen ground, caliche, and high-density rock formations. Featuring a dual-point, aggressive "Twin Tiger" profile, these teeth are designed to act as a pick, fracturing hard surfaces that standard or even single-tiger teeth cannot penetrate. Optimized for the Caterpillar E200B through E345 series, the LC series ensures your machine maintains high productivity and low cycle times in high-resistance digging conditions.

1. Core Advantages

Dual-Point Penetration: The twin-point design maximizes the piercing capability of the machine, effectively fracturing hard-packed ground and sedimentary rock with precision.
Self-Sharpening Twin Profile: Engineered to maintain its sharp piercing edges as the material wears down, ensuring consistent performance and preventing "blunting" throughout its service life.
High-Strength Alloy Casting: Manufactured from specialized high-tensile alloy steel and through-hardened to resist the extreme impact and prying forces common in rock excavation.
Reduced Fuel Consumption: By significantly lowering the resistance during the digging cycle, these teeth reduce the strain on the excavator's hydraulic system and lower overall fuel costs.
Secure J-Series Compatibility: Fully compatible with standard Caterpillar J-Series side-pin adapters, utilizing the reliable pin and retainer system for a secure, fail-safe fit.

2. Technical Specifications & LC Part Numbers

Machine Model	LC Part Number	J-Series Size Equivalent	Primary Site Application
E200B / E315	LC300TL	J300	Hardpan / Frost / Trenching
E320 / E322	LC350TL	J350	Caliche / Compacted Strata

E345 / E349	LC550TL	J550	Heavy Mining / Rock Excavation

3. Key Structural Features

Aggressive Twin-Point Profile: Tailored specifically to maximize point-load stress and crack the toughest penetration barriers.
Enhanced Service Stability: Designed with a precision-machined inner pocket configuration that dampens excessive movement and wobble on the adapter nose.
Toughened Core Metallurgy: Employs structured through-hardening profiles to stop sudden snapping or point shearing in high-impact rock matrices.

4. Application Note & Selection Advisory

Technical Allocation Protocol:
• Penetration vs. Wearing Volume: The Twin Tiger Long (TL) profile is highly specialized for maximum structural penetration. For geological environments where extreme surface abrasion resistance is more critical than fracturing ability (such as loading loose quartz sand or crushed abrasive gravel), we highly recommend substituting our J-Series Heavy Duty or Standard Long tips to maximize wear life.
• Locking Pins: To ensure optimal retention and avoid field detachment, always discard old, fatigued side pins and sleeve retainers. Install fresh matching J-Series pin sets during each G.E.T. overhaul.
