Wheeled Excavators
Rubber-tyred excavators that travel between work points on a road at their own speed, used mainly for utility maintenance, verge work and municipal contracts. They trade stability for mobility.
Features
- Road travel at up to around 35 km/h removes the transporter from short, repeated site moves.
- Outriggers, a dozer blade, or both, are what restore digging stability once the machine is on tyres.
- Axle configuration is specified as rigid or oscillating front, which decides behaviour on a cambered verge.
- Road lighting, indicators and a braked configuration are needed before the machine can be registered for public roads.
- Twin tyres or wide single tyres change flotation and the width the machine occupies inside a lane closure.
Specifications
| Figure | Typical range | Unit | Why it matters |
|---|---|---|---|
| Operating weight | 9 000 - 21 000 | kg | Interacts with road-registration limits as well as digging stability. |
| Travel speed | 20 - 35 | km/h | Decides whether self-drive between work points is realistic. |
| Stabiliser configuration | blade plus outriggers | Sets lift capacity over the side and behaviour on camber. | |
| Maximum reach at ground level | 8 000 - 9 500 | mm | Governs how much of a carriageway can be worked from one setup. |
