Amulet B.R.U.T Rigid Thumb Attachments | Model Nitro Series | Machine Size 3-50 Tons | For Excavators
DESCRIPTION
The Amulet B.R.U.T Nitro Series Rigid Thumb Collection delivers a complete range of heavy-duty mechanical excavator thumbs engineered for 3–50 ton machine classes. Designed for maximum versatility, each model in the BN and B Series lineup provides powerful material control for demolition, land clearing, scrap handling, and logging applications.
Built with high-strength alloy steel construction, these rigid thumbs feature multi-serrated tines, reinforced mounting geometry, and heat-treated pins to ensure long-lasting durability under extreme workloads. The non-hydraulic mechanical design eliminates complex systems while maintaining reliable gripping performance across all job conditions.
From compact 3–8 ton excavators (335–400 lb units) to ultra-heavy 40–50 ton class configurations, each model is optimized for its machine category with balanced strength, precise fitment, and low maintenance requirements. With multiple sizing options, contractors can match the exact thumb configuration needed for efficiency, safety, and productivity on demanding job sites.
Key Features
- Full Excavator Size Coverage (3–50 Ton) Covers a complete range of machine classes from 3-ton compact excavators to 50-ton heavy-duty machines, ensuring compatibility across construction, demolition, and forestry fleets with consistent performance and strength.
- BN & B Series Model Flexibility Includes multiple configurations such as BN-2, BN-3, BN-4, BN-5, BN-6, BN-7, and B-Series NT models, allowing precise matching of thumb strength and size to specific excavator requirements.
- Heavy-Duty Alloy Steel Construction Each thumb is built using reinforced alloy steel structures, delivering exceptional resistance to bending, impact, and fatigue during high-intensity demolition and material handling operations.
- Multi-Serrated High-Grip Tines The serrated tine design enhances grip strength for irregular materials like rock, logs, scrap metal, and debris, improving control and reducing load slippage during operation.
- Heat-Treated Pin System Equipped with heat-treated steel pins for improved durability and wear resistance, ensuring long-term performance even under continuous heavy-load working environments.
- Mechanical Non-Hydraulic Design A fully mechanical thumb system eliminates hydraulic dependency, reducing maintenance complexity while providing reliable and consistent operation in rugged job conditions.
- Multi-Class Weight Optimization Each model is optimized within its class, ranging from 335 lb compact units to 1500 lb heavy-duty thumbs, ensuring proper balance and performance per excavator size.
- Demolition & Land Clearing Ready Engineered specifically for demolition, land clearing, forestry, and scrap handling, making it a versatile attachment for multiple construction industry applications.
- Compact to Heavy-Duty Length Scaling Designed with 30 in to 78+ in overall length range, ensuring proper reach and control depending on excavator size and application needs.
- Low Maintenance Operation With no hydraulic components, the system offers reduced maintenance needs, fewer failure points, and lower long-term operating costs for contractors.
