In heavy machinery manufacturing, every component’s performance directly impacts equipment efficiency, operational costs, and lifespan. When it comes to structural components such as excavator booms and crane jibs, traditional metals tend to have their limitations: they’re sturdy yet heavy, resistant to wear but susceptible to corrosion, and inflexible when it comes to accommodating new design requirements. Our carbon fiber tubes redefine what’s possible, blending aerospace-grade strength with the ruggedness heavy machinery demands.
Heavy machinery operates in tough conditions—constant vibration, heavy loads, exposure to dirt, moisture, and extreme temperatures. Our carbon fiber tubes are engineered to thrive here:
Crafted from
T700/
T800 grade carbon fiber and industrial-grade epoxy resin, these tubes deliver tensile strength up to 4200MPa (T800) while weighing just 1.58-1.6g/cm³—about 1/5 the density of steel. For heavy machinery, this translates to:
- Reduced fuel consumption: Lighter structural parts (e.g., crane outriggers, bulldozer arms) cut overall equipment weight by 30-40%, slashing fuel use by 10-15% per operation.
- The new material offers a higher load capacity—despite being lighter, it can support static loads up to 500 kN and withstand energetic impacts from sudden weight changes more effectively than steel. This reduces the likelihood of bending or fractures under heavy or fluctuating loads.
Heavy machinery doesn’t work in labs—it operates in mines, construction sites, and industrial yards. Our tubes are tested to survive:
- Extreme temperatures: Functions reliably from -50℃ (cold storage facilities) to 180℃ (foundry environments).
- Corrosion resistance: Resists rust from rain, mud, and chemical spills (pH 3-11), outlasting steel by 3-5 times in wet or high-humidity settings.
- Vibration & fatigue: Endures 10,000+ cycles of high-frequency vibration (up to 500Hz) without performance drop—critical for machinery like asphalt pavers or mining drills.
No two heavy machines are identical, and our tubes adapt to your exact specs:
- Sizes for large-scale parts: Diameters range from 10mm (smaller linkages) to 34mm (structural beams), with wall thicknesses up to 4mm for high-load areas. Lengths up to 6m fit long-span components like conveyor frames.
- Custom shapes & finishes: Round, square, or hexagonal profiles—even (special-shaped) designs for unique joints. Choose matte or textured surfaces to resist scratches from debris.
