J800 6I8802TL / 618802TLF Tooth Tiger Long for CAT 390

Product Overview

With a precision-engineered weight of 46.7KG, the attachment balances lightweight agility with robust forging strength: its lighter build reduces strain on the excavator’s arm while its forged steel construction resists wear from coal dust, frozen soil, and hard rock. This combination makes it a cost-effective solution for operations where frequent tooth replacement due to harsh conditions would otherwise disrupt productivity. Whether used for coal extraction, frozen ground excavation, or heavy-duty material handling, the J800 6I8802TL / 618802TLF ensures seamless integration with the CAT 390 and other compatible models, delivering consistent performance and extended service life.

Core Technical Parameters

Forging & Material Details

A key differentiator of the J800 6I8802TL / 618802TLF is its forging manufacturing process (labeled as "FORGINGTOOT" in product documentation):

· Material: High-strength alloy steel forged under high temperature and pressure, enhancing tensile strength and impact resistance—critical for withstanding frozen ground’s rigidity and coal mine dust’s abrasiveness.

· Surface Treatment: A specialized anti-corrosion coating added post-forging, preventing rust and degradation in damp coal mine environments or freezing temperatures.

· Tip Geometry: Extended "long tooth" design with a tapered, sharpened edge, optimized for penetrating compacted coal seams and frozen soil without excessive hydraulic force.

Features

1. Forged Steel Durability for Extreme Conditions

The J800 6I8802TL / 618802TLF is crafted via precision forging—a process that compresses alloy steel molecules to create a denser, stronger structure than cast or machined alternatives. This forging strength makes it highly resistant to chipping, bending, and wear, even when exposed to the dual challenges of coal mine operations (abrasive coal dust, constant contact with rock) and frozen ground (rigid soil that strains standard teeth). Unlike generic teeth that may crack after weeks in frozen conditions, this model maintains structural integrity, reducing replacement frequency by up to 40%.

2. Broad Compatibility Beyond CAT 390

While optimized for the CAT 390, the attachment is engineered to fit multiple high-powered excavators: CAT 395, XE1250, XE1350, and ZE1250. This versatility is enhanced by its alternate part numbers—XCMG code: 819962819 and Zhe Dong 6I8802TD—allowing operators with mixed fleets to standardize on a single, reliable tooth. No custom modifications are needed for compatible machines, saving time and reducing the risk of fitment-related damage.

3. Lightweight Design with Efficient Penetration

At 46.7KG, the J800 6I8802TL / 618802TLF is lighter than many heavy-duty teeth (which often exceed 60KG), reducing strain on the excavator’s hydraulic system and arm components. Despite its lighter weight, its extended "long tooth" profile and sharpened tip concentrate force to ensure efficient penetration—critical for breaking through frozen ground or dense coal seams. This balance of light weight and penetration power translates to lower fuel consumption for the CAT 390 and faster cycle times for excavation tasks.

4. Tailored for Coal Mine & Frozen Ground Use

Every design element of the Tooth Tiger Long addresses the unique challenges of its target environments:

· Anti-Abrasion: Forged steel resists wear from coal dust, which can quickly degrade standard teeth.

· Low-Temperature Resistance: The alloy steel formulation remains ductile in freezing temperatures (down to -30°C), preventing brittleness that leads to cracking in frozen ground.

· Debris Release: A smooth, streamlined surface reduces coal dust or frozen soil buildup, ensuring the tooth maintains its penetration efficiency without frequent cleaning.

Applications

The J800 6I8802TL / 618802TLF Tooth Tiger Long is purpose-built for industries and tasks that demand durability in extreme, specialized conditions—leveraging its compatibility with the CAT 390 and other models to deliver value across sectors:

1. Coal Mine Operations

In underground or open-pit coal mines, the attachment excels at extracting coal from seams and loading it onto transport vehicles. Its forged steel construction resists abrasion from coal dust and rock fragments, while its long tooth design reaches deep into coal seams to maximize extraction volume. For CAT 390 operators in coal mines, this tooth reduces downtime by lasting 2–3 times longer than standard teeth, ensuring continuous production.

2. Frozen Ground Excavation (Frozen King Conditions)

In cold regions where soil freezes solid (often referred to as "Frozen King" conditions)—such as northern mining sites or winter construction projects—the J800 6I8802TL / 618802TLF is indispensable. Its low-temperature-resistant steel and sharp tip penetrate frozen soil without cracking, making it ideal for tasks like:

· Preparing mining sites in winter

· Digging foundations for infrastructure in cold climates

· Clearing frozen terrain for pipeline installation

Its compatibility with the CAT 390 ensures precise control, even when working with unpredictable frozen ground.

3. Heavy-Duty Quarrying for Soft Minerals

Beyond coal, the attachment performs well in quarries extracting soft to medium-hard minerals (such as limestone or gypsum). Its lightweight design allows the CAT 390 to handle frequent loading cycles, while its forging strength resists wear from mineral deposits. The long tooth profile also helps loosen compacted mineral piles, improving loading efficiency.

4. Large-Scale Agricultural Land Preparation (Cold Climates)

In agricultural regions with long winters, the J800 6I8802TL / 618802TLF aids in spring land preparation by breaking up frozen topsoil. Farmers and agricultural contractors using the CAT 390 or CAT 395 can use this tooth to speed up soil tilling, ensuring crops are planted on time despite late-season frost.

FAQ

1. Can the J800 6I8802TL / 618802TLF be used with excavators outside the listed models?

No, the attachment is only compatible with the CAT 390, CAT 395, XE1250, XE1350, and ZE1250. Its mounting dimensions, weight distribution, and force tolerance are calibrated exclusively for these machines. Using it with other models (e.g., CAT 385 or non-specified XE series) may cause poor fit, reduced performance, or damage to the excavator’s arm. For teeth compatible with other machines, contact GETPLUS customer support.

2. What is the difference between part numbers 6I8802TL and 618802TLF?

The 6I8802TL and 618802TLF are functionally identical—both are J800-sized Tooth Tiger Long attachments for the CAT 390 and compatible models. The "F" in 618802TLF denotes a minor batch variation in surface coating (a slightly thicker anti-corrosion layer) for use in extra-damp coal mines or coastal frozen environments. For most users, either part number will perform equally; choose 618802TLF if your operations involve prolonged exposure to moisture.
