Swing Function
What distinguishes excavators from other construction equipment is their swing function. It makes it possible for the excavator to rotate its upper body, which improves efficiency and maneuverability in tight areas.
The swing function is essential for tasks such as:
- Precision Digging: Digging in confined spaces is made easier by the excavator’s rotational capability.
- Material handling: By swinging the bucket or attachment, materials can be repositioned more effectively and with less movement.
| Modèle d'excavateur | Vitesse de swing (tr / min) | Swing Radius (m) | Meilleur cas d'utilisation |
|---|---|---|---|
| CAT 320D | 10 | 3.8 | Urban, demolition work |
| Komatsu PC200-8 | 9 | 4.0 | Foundation work, grading |
