Heavy machinery has always relied on steel and aluminum for structural integrity. But as fuel costs rise and emission regulations tighten, equipment manufacturers are actively looking for lighter alternatives that do not compromise strength.
Zibo Runfeng CFRP Co. now offers filament wound large diameter carbon fiber tubes specifically engineered for heavy machinery applications. These tubes replace traditional metal components in booms, frames, support structures, and hydraulic equipment, delivering significant weight savings without sacrificing load capacity.
For engineers designing the next generation of excavators, cranes, agricultural equipment, and mining machinery, carbon fiber composite tubes provide a practical path toward lighter equipment, higher payloads, and lower operating costs.
Not all carbon fiber tubes are created equal.
For heavy machinery, large diameter carbon fiber tubes must withstand multi-directional loads, including bending, torsion, and compression. Our filament winding process ensures that continuous carbon fibers are placed precisely along the load paths, delivering optimal strength where it is needed most.
Key benefits of filament winding for heavy machinery applications:
1. High fiber volume fraction
Continuous fibers without overlaps or gaps.
2. Customizable fiber orientation
Various options are available, including custom angles, circumferential winding, or axial reinforcement, depending on your load conditions.
3. Seamless one-piece construction
No weak points from joints or welds.
4. Excellent fatigue resistance
Carbon fiber does not suffer from cyclic fatigue like metals.
This makes our filament winding carbon fiber tubes ideal for components that experience constant vibration, impact, and heavy loading in demanding industrial environments.
Real Weight Reduction for Real Machinery
Weight reduction is not just about making equipment easier to move. It directly affects:
Fuel consumption-Lighter machines burn less fuel
Payload capacity-Every kilogram saved on structural weight becomes available for cargo or attachments
Component life-Lower inertia and reduced stress on bearings, seals, and hydraulic systems
Transportation and assembly-Easier to ship and install on site
For example, replacing a steel boom tube on a mobile crane with a filament winding carbon tubes can reduce component weight by 60-70% while maintaining the same stiffness and strength envelope.
Our filament winding process gives us the flexibility to produce large diameter carbon fiber tubes up to 1000mm in diameter and 14000 mm in length, which is exactly what the heavy machinery industry needs.
We also offer design support to help your engineering team transition from metal to composite tube designs, including end connection engineering and failure mode analysis.
