Medium Excavators
The 10 to 30 tonne classes that do most general earthworks, drainage and foundation digging. They carry breakers and couplers without re-plumbing and still move on a standard low-loader.
Features
- Two-piece and variable-geometry booms give extra reach close in, useful when loading over a trench box or a wall.
- Cylinder guards and a reinforced undercarriage are the usual specification for demolition and recycling yards.
- Bucket and coupler combinations are the main wear cost in this class, so pin sizes and coupler standards should be fixed across a fleet.
- Two-speed travel motors shorten site moves without needing a transporter for short hops.
- Breaker piping with a return filter and a dedicated case-drain line is a factory option worth ordering rather than retrofitting.
Specifications
| Figure | Typical range | Unit | Why it matters |
|---|---|---|---|
| Operating weight | 13 000 - 29 000 | kg | Sets the carrier class for breakers and the transport category. |
| Bucket capacity | 0,55 - 1,50 | m3 | Matched to truck body volume to avoid part loads. |
| Bucket breakout force | 85 - 160 | kN | Decides whether the machine can cut hard ground without a ripper tooth. |
| Track shoe width | 500 / 600 / 700 / 800 | mm | Trades ground pressure against transport width and turning wear. |
| Maximum loading height | 6 000 - 7 000 | mm | Must clear the body sides of the trucks actually on the job. |
