Programmatic Comparison · Engineering Brief
ARJES Impaktor 250 EVO II vs Hammel VB 750 — 2-hour cassette swap vs 24-48h hardfacing, 14t hooklift vs 25t transport, monolithic shaft TCO penalty.
| Spec | ARJES Impaktor 250 EVO II | Hammel VB 750 |
|---|---|---|
| Drive concept | Twin-shaft asynchronous low-speed hydro-mechanical, independent reverse | Interlocking twin-shaft low-speed hydrostatic |
| Engine | Volvo Penta TAD 581 VE (Stage V) | Volvo Penta / CAT (Stage V) |
| Drive power (kW) | 129 | 260 |
| Drive power (HP) | 175 | 350 |
| Operating weight (kg) | 14 000 (hook-lift legal) | ~25 000 (borderline standard transport) |
| Fuel consumption (l/h, avg) | 15 – 20 | 20 – 30 |
| Specific fuel (l/t, C&D) | 0.27 | 0.30 – 0.35 |
| Shaft / rotor type | Quick-change cassette (shafts + bearings + gear) | Interlocking twin-shaft (monolithic standard) |
| Shaft maintenance downtime | 2 hours (cassette swap) | 24 – 48+ hours (field hardfacing) |
| EU 40t GVW transport compliance | Standard (hook-lift truck, zero permits) | Borderline (~25t, occasionally standard with lightweight trailer) |
| Hydraulic thermal limit (°C ambient) | +42 (CLEANFIX reversible cooling) | Standard (hydrostatic at 349 HP, moderate heat load) |
| Setup time (hrs) | 0.5 (SCU auto-calibration, hook-lift) | 1.0+ (lowboy unload + setup) |
| Material | ARJES Impaktor 250 EVO II | Hammel VB 750 |
|---|---|---|
| C&D waste / reinforced concrete | 44-66 ST/h | 33-55 ST/h |
| Waste wood / biomass | 17-22 ST/h | 22-39 ST/h |
| Commercial / industrial waste | 33-55 ST/h | 28-44 ST/h |
| Reinforced concrete (rebar ≥ 16 mm) | On-demand shred (asynchronous anti-wrap) | Hydrostatic reversal (interlocking shafts) |
Gate fees, landfill taxes, and electricity prices swing the verdict by ±30%. Run the live TCO model for your region to see real payback.
Both are mobile twin-shaft shredders, but in different weight and power classes: the Hammel VB 750 weighs ~25 t with a 260 kW engine, while the ARJES Impaktor 250 EVO II is 14.0 t with 129 kW. They are commonly compared for C&D and scrap processing where hooklift logistics and shaft maintenance are deciding factors — the Hammel is the heaviest machine that still approaches standard transport parameters.
At ~25 t, the Hammel VB 750 sits closest to the standard transport threshold among all tracked heavy shredders. Depending on the specific regional enforcement of axle-weight distribution and the lightweight trailer configuration utilized, it may occasionally fit within standard transport parameters. However, at 25 t payload plus a ~15 t truck and trailer, the combined GVW of ~40 t sits precisely at the EU legal limit, meaning even minor variations in trailer tare weight or axle spacing can push it into wide-load/overweight territory.
For CEE multi-site C&D deployments, the ARJES Impaktor 250 EVO II delivers substantially lower TCO through 0.27 l/t specific fuel, 2-hour cassette swaps eliminating 24-48h hardfacing, and zero heavy-haul permit costs. For high-volume single-site waste-wood lines, the Hammel VB 750 wins on throughput per hour and may justify its borderline transport overhead.
