Features

1. Heavy-Duty Build for Extreme Durability

The J800 6I8802RC is crafted from premium, heat-treated alloy steel, a material chosen for its exceptional resistance to impact, bending, and abrasion. Its 72KG weight is a deliberate design choice, providing the mass needed to absorb the shock of repeated rock strikes while maintaining structural integrity. This durability ensures the chisel can handle daily use in harsh environments (such as quarries or mining sites) without cracking or dulling, significantly extending its service life compared to standard chisels.

2. CAT 390-Specific Compatibility

Every dimension of the J800 6I8802RC is calibrated to match the CAT 390 excavator’s original equipment standards. This includes precise alignment with the machine’s hydraulic connections, arm mounting points, and weight distribution—ensuring the chisel works in harmony with the CAT 390’s power and precision. No aftermarket modifications are required, saving time during installation and reducing the risk of compatibility-related equipment damage.

3. Efficient Penetration Design

The chisel’s tapered, sharpened tip is engineered to minimize surface area contact, focusing the CAT 390’s hydraulic force into a small, high-pressure point. This design allows the J800 6I8802RC to penetrate rock, concrete, or compacted soil with less effort, reducing strain on the excavator’s hydraulic system and improving overall work efficiency. Whether breaking boulders or excavating hard ground, the chisel delivers consistent, reliable performance.

4. Low Maintenance Requirements

Thanks to its wear-resistant coating and robust material, the J800 6I8802RC requires minimal maintenance. Unlike lesser-quality chisels that need frequent sharpening or repair, this model retains its sharpness and structural integrity over time. Routine checks (such as inspecting for loose mounting bolts) are simple to perform, and the chisel’s design minimizes debris buildup—further reducing maintenance time and costs.

Applications

The J800 6I8802RC Tooth Rock Chisel is purpose-built for industries where the CAT 390 excavator is relied on to handle hard, dense materials. Its applications span sectors that demand efficient rock-breaking and hard-material excavation:

1. Quarry Operations

Quarries require tools that can break large, solid rock formations into manageable sizes for processing. The J800 6I8802RC excels here, using its sharp tip and 72KG weight to split limestone, granite, and other quarried stones. Its durability stands up to the constant impact of rock-on-rock contact, ensuring quarries can maintain steady production without frequent chisel replacements.

2. Mining Industry

In underground or open-pit mining, the J800 6I8802RC is used to break up ore deposits (such as coal, iron ore, or copper) and clear rock debris from mining tunnels. Its ability to penetrate hard rock efficiently reduces the time needed to access mineral reserves, while its wear resistance handles the abrasive nature of mining materials—keeping mining operations running smoothly.

3. Demolition and Construction

For demolition projects (such as tearing down old buildings or bridges) or heavy construction (such as excavating foundations for skyscrapers), the J800 6I8802RC is invaluable. It can break through reinforced concrete, brick walls, and asphalt, making it easier to clear sites and prepare for new construction. Its compatibility with the CAT 390 ensures precise control, allowing operators to target specific areas without damaging surrounding structures.

4. Infrastructure and Road Construction

Road and highway construction often requires excavating through hard soil or rock to create level terrain or lay underground utilities. The J800 6I8802RC efficiently breaks up these hard materials, enabling crews to dig trenches, build road bases, and construct drainage systems. Its performance ensures infrastructure projects stay on schedule, even when faced with unforeseen hard ground conditions.

FAQ

1. Can the J800 6I8802RC Tooth Rock Chisel be used with excavators other than the CAT 390?

No, the J800 6I8802RC is specifically designed for the CAT 390 excavator. Its mounting dimensions, weight distribution, and force compatibility are calibrated exclusively for the CAT 390’s hydraulic system and arm design. Using it with other excavator models may result in poor performance, equipment damage, or safety hazards. For chisels compatible with other machines, please contact GETPLUS customer support.

2. How does the J800 6I8802RC compare to standard rock chisels?

The J800 6I8802RC outperforms standard rock chisels in three key ways:

· Durability: It uses heat-treated alloy steel and a wear-resistant coating, whereas standard chisels often use lower-grade steel that dulls or cracks quickly.

· Compatibility: It is tailored to the CAT 390, ensuring optimal performance, while standard chisels are generic and may not align with the machine’s capabilities.

· Penetration: Its tapered tip design concentrates force for faster, easier rock breaking, whereas standard chisels have broader tips that require more hydraulic power.

3. What maintenance steps are required for the J800 6I8802RC?

Routine maintenance for the J800 6I8802RC is simple and includes:

1. Inspections: Check the chisel tip for wear or damage (e.g., cracks, dulling) before each use. If the tip is excessively worn, sharpen it using a grinder designed for alloy steel.

2. Mounting Checks: Ensure the chisel is securely fastened to the CAT 390’s arm—tighten any loose bolts to prevent movement during operation.

3. Cleaning: Remove debris (such as rock dust or dirt) from the chisel after use to prevent buildup that could affect performance or cause corrosion.

For heavy-use scenarios (e.g., daily mining), we recommend a more thorough inspection every 2 weeks.

4. What is the expected service life of the J800 6I8802RC?

The service life of the J800 6I8802RC depends on usage conditions:

· In moderate use (e.g., occasional construction demolition), it typically lasts 12–18 months.

· In heavy use (e.g., daily quarry or mining operations), it lasts 6–10 months.

Proper maintenance (such as regular sharpening and cleaning) can extend this lifespan by up to 30%. If the chisel shows signs of severe damage (e.g., large cracks in the body), replace it immediately to avoid safety risks.
