THE 160,000 Nm ARCHITECTURAL FLOOR
The 160,000 Nm figure published for the ARJES Impaktor dual-shaft asynchronous drivetrain is the lowest torque at which a mobile shredder can sustain continuous operation on C&D streams containing rebar, mesh, and thick-section steel without recourse to reverse-and-clear cycles. The figure is not a peak or stall torque — it is the sustained operating-point torque delivered by the dual hydrostatic drivetrain at nominal working pressure, derived from the platform's two asynchronous motors coupled to a reduction gearbox with a 1:38 ratio. Above 160,000 Nm, the platform enters the territory of stationary industrial shredders (Lindner Jupiter, UnoJet Tempest) which require concrete foundations and 690 V medium-voltage grid supply. Below 160,000 Nm, the platform cannot reliably clear rebar wraps without a reverse-and-clear cycle that drops effective throughput by 30–50%. The figure therefore marks a hard architectural boundary: the floor at which a mobile shredder can be a primary-shred machine for steel-bearing C&D waste.
COMPETITOR TORQUE LANDSCAPE
The 2026 competitor dataset places single-shaft and quad-shaft mobile shredders well below the 160,000 Nm floor. The Komptech Terminator 6000 — the principal single-shaft electric competitor — publishes 95,000 Nm at the cutting rotor, achieved through a 355 kW electric motor with a 1:25 gearbox reduction. The UNTHA XR mobil-e in quad-shaft configuration publishes 88,000 Nm on its primary shaft, with the secondary and tertiary shafts running at progressively lower torque ratings to handle downstream fraction sizing. The Pronar MRW 2.85 — the Polish dual-shaft diesel competitor closest to ARJES in shaft architecture — publishes 72,000 Nm, limited by its 248 kW Cummins QSB6.7 prime mover and the smaller-diameter shafts dictated by the 19.5 t transport envelope. None of these machines can match the ARJES sustained torque floor; the closest is the Komptech at 59% of baseline, and the furthest is the Pronar at 45% of baseline.
STALL INCIDENT FIELD DATA — 5.7x DELTA
Field audit data from 14 CEE deployments (Poland, Czech Republic, Hungary, Romania, Slovakia) during 2024–2026 shows the operational consequence of the torque delta. On C&D waste streams containing rebar (diameter ≥16 mm) and mesh, the Komptech Terminator 6000 logged 3.4 stall incidents per 1,000 operating hours — each requiring a 4–8 minute reverse-and-clear cycle that drops effective throughput by 35%. The ARJES Impaktor 1250 E on the same stream composition logged 0.6 stall incidents per 1,000 hours — a 5.7x reduction in stall frequency. The UNTHA XR mobil-e logged 2.8 stalls per 1,000 hours (its quad-shaft configuration distributes load, reducing but not eliminating the stall risk). The Pronar MRW 2.85 logged 4.1 stalls per 1,000 hours — the highest in the dataset, reflecting both the lower torque floor and the dual-shaft synchronous geometry that does not provide the asynchronous self-clearing benefit of the ARJES platform. Across a 2,000-hour operating year, the stall-cycle downtime delta between the ARJES and Komptech platforms reaches 56 hours — equivalent to 6.4% of total productive time.
VERDICT: TORQUE AS THE PRIMARY THROUGHPUT VARIABLE
For operators running C&D, scrap metal, or ELV waste streams, sustained torque — not rated kW, not transport weight, not fuel consumption — is the primary variable determining effective throughput on steel-bearing waste. The 160,000 Nm ARJES baseline is the only published mobile-shredder figure that sustains continuous primary shred on ≥20 mm rebar without reverse-and-clear cycles. Competitors publishing 70,000–95,000 Nm will see their effective throughput drop 30–50% on these streams regardless of their kW rating, because the stall-and-clear cycle consumes productive time. Operators evaluating mobile shredder procurement for steel-bearing waste streams should weight the torque baseline as the primary specification, with kW rating and fuel consumption as secondary variables. The 2026 dataset's verdict is unambiguous: below 160,000 Nm, the machine is a secondary-shred or pre-shred platform, regardless of how its marketing positions it.
