Choosing the wrong tonnage means either a machine that bogs down in clay or one you cannot get through the gate. For rental fleets and contractors, tonnage is the single biggest ROI lever — get it wrong and the machine sits, or worse, damages the job.
1. The 1-ton micro excavator (LUYRN HL10)
Built for interior demolition, landscaping, and narrow utility trenches.
- Width under 1000 mm — fits standard garden gates.
- Ground pressure low enough to spare finished lawns and driveways.
- Max dig depth ~1600–1800 mm.
2. The 3.5-ton compact (LUYRN HL35u)
Foundations, drainage, heavier lifts.
- Counterweight gives stability for hydraulic breakers and large augers.
- Higher breakout force in compacted or rocky soil.
- Max dig depth ~3000–3300 mm.
3. Spec comparison
| Feature | 1-Ton (HL10) | 3.5-Ton (HL35u) |
|---|---|---|
| Engine output | 10–12 kW | 18–25 kW |
| Bucket capacity | 0.02–0.03 m³ | 0.10–0.12 m³ |
| Tail swing | Conventional | Zero / reduced |
| Transport | Standard trailer | Heavy-duty plant trailer |
4. Zero tail swing — why urban crews pay for it
The HL35u rotates within its track width, so you will not clip a wall or a parked car on a tight footpath. On confined city jobs this alone justifies the 3.5 t over a cheaper 1 t.
5. Transport and permits
A 1 t rides behind a car trailer; a 3.5 t needs a licensed plant trailer and sometimes an oversize permit for the counterweight. Factor that into your daily rate when you quote the job.
Frequently asked questions
Q: Can a 1-ton excavator break concrete?
Only thin slab with a micro-breaker. For real demolition, run a 3.5 t with a hydraulic breaker.
Q: Which holds value better at resale?
3.5 t units resell faster in most markets because the job fit is broader.
Q: Do I need retractable tracks?
For indoor or frequent gate work, yes. See our excavator attachments guide for quick-hitch options that make one machine do both jobs.
