What is the Difference Between Axial and Transverse Drum Cutters?
While transverse drum cutters have drums rotating to the sides, in Axial Drum Cutters, the drum rotates in line with the excavator boom. This design difference makes the axial cutter unrivaled in certain specific jobs.
So, when should you choose a vertical (axial) cutter instead of a horizontal one?
1. Pile Head Cutting
In foundation construction, after pouring concrete for bored piles, the excess poor-quality concrete at the top must be removed. Hydraulic breakers can damage the steel reinforcement inside.
The Axial Drum Cutter:
- Gently grinds the concrete from between the rebar.
- Does not damage the steel.
- Leaves a very fast and clean surface.
2. Narrow Trenching
Imagine needing to open a narrow trench for water or cable lines in the city. Transverse cutters might be too wide to fit inside.
Axial cutters, with their cylindrical design, can easily enter the trench and dig deep. They can go anywhere your boom can reach.
3. Axial vs. Transverse Comparison
| Application | Transverse Cutter | Axial Cutter |
| Tunnel Profiling | Excellent | Medium |
| Narrow Trenching | Difficult (Too wide) | Excellent |
| Pile Head Cutting | Not Suitable | Best Solution |
| Shaft / Hole Digging | No | Yes |
Frequently Asked Questions (FAQ)
Q: Can I break rock with an axial cutter?
A: Yes, you can cut and fracture medium-hard rocks (limestone, etc.) especially in narrow spaces or where breakers are prohibited.
Q: Are the picks replaceable?
A: Yes, the tungsten carbide picks (teeth) are held by snap rings and can be easily replaced on site. Changing worn picks on time protects the drum body.
