Develon 32 t Series 9 excavator: safety and reach upgrades for project teams
Reviewed by Joe Ashwell
First reported on The Construction Index
30 Second Briefing
Develon has launched the 32‑tonne DX300LC‑9 excavator to its Series 9 range, powered by a DX08 engine delivering 207 kW at 1,800 rpm and 1,230 kgf·m torque, with a maximum digging depth of 7.3 m and reach of 10.5 m. A super long reach variant, the DX300SLR‑9, extends reach by a further metre over the previous DX300SLR‑7 for applications such as riverworks and slope stabilisation. The machine adds electro‑hydraulic control, 360° Smart Around View Monitor, AI‑based person detection with E‑Stop, virtual walls, Advanced Lift Assist and ultra‑low 67 dBA cab noise.
Technical Brief
- Fully electro-hydraulic control system enables finer motion tuning and integration of multiple assistance functions.
- Cab soundproofing achieves 67 dBA, around 3 dBA quieter than typical 30‑tonne excavators.
- 360° Smart Around View Monitor is standard, giving continuous visual coverage of blind spots.
- AI-based person detection links to an E‑Stop that halts machine movement when intrusion occurs.
- Virtual wall functionality lets supervisors define exclusion zones above and below machine working envelope.
- Advanced Lift Assist provides real-time tipping risk warnings during heavy lifts or long‑reach operations.
- Breaker Assist prevents blank firing, reducing risk of tool, boom and mounting bracket damage.
Our Take
Develon’s 32 t-class DX300LC-9 slots into a size band that is heavily represented at Hillhead 2026, where our coverage shows rival 30 t excavators from JCB, Komatsu, Hitachi and others, so the lower 67 dBA in-cab noise and 360° camera system are likely aimed at differentiating on operator comfort and safety in that crowded UK market.
The machine’s 1 m reach increase on the SLR variant, combined with Develon’s growing UK distribution footprint via dealers such as Gordons Construction Equipment, suggests the company is positioning this model to win quarry and civils work where long-reach duties and tight site access are common.
With Manitou’s cross-distribution arrangement with HD Construction Equipment already putting Develon kit into more mixed fleets, the Series 9 excavator’s safety-focused features (noise reduction and full camera coverage) are likely designed to appeal to rental and port operators who must standardise risk controls across multiple OEM brands.
