Verdict

Advantage

25% more cutting torque despite 15 kW less power

The ARJES Bonfiglioli 350 000 Nm gearbox delivers 25% more cutting torque than the Atlas Copco ST 1000’s published 280 000 Nm peak — despite the Atlas Copco carrying 15 kW (2.5%) more prime-mover power.
On contaminated C&D feedstock with embedded rebar and concrete chunks, this torque reserve directly reduces stall frequency and recover-from-stall cycle time.

Advantage

9 tonnes lighter — 19% lower transport class

The Impaktor 1100 weighs 38 000 kg against the Atlas Copco ST 1000’s 47 000 kg.
This drops the machine out of the heavy-haul permit class in several jurisdictions, eliminates escort vehicle requirements, and reduces per-move transport cost by approximately EUR 1 800 within the EU.

Advantage

9× faster shaft change (2 h vs 18 h)

ARJES quick-change cassette completes a shaft swap in ~2 hours.
The Atlas Copco ST 1000 requires approximately 18 hours of in-frame work including rotor removal and bearing service — a 9× difference that translates to ~120 hours of additional annual production availability on mixed-feed yards.

Advantage

25% longer hydrostatic service interval

ARJES 500-hour hydrostatic service interval beats Atlas Copco’s 400-hour schedule by 25%.
Over a 10 000-hour horizon, the ARJES operator saves ~5 planned service stops and ~50 hours of downtime — meaningful for multi-shift operations where every service window requires production halts.

Competitor edge

Atlas Copco ships with 15 kW more prime-mover power

For operations feeding homogeneous low-contamination feedstock at continuous rated load, the Atlas Copco ST 1000’s 600 kW Volvo Penta TWD1643VE delivers marginally higher steady-state throughput.
ARJES compensates with a 25% torque reserve advantage that matters more on real-world contaminated C&D feedstock.

Frequently Asked Questions

Is the ARJES Impaktor 1100 directly comparable to the Atlas Copco ST 1000?

Yes. Both machines are heavy-class mobile twin-shaft shredders in the 575–600 kW range, targeting C&D, commercial waste, and scrap metal. The Impaktor 1100 delivers 25% more cutting torque at 9 tonnes lower operating weight, while the Atlas Copco ST 1000 ships with 15 kW more prime-mover power.

Which shredder has lower total cost of ownership over 10 000 hours?

The ARJES Impaktor 1100 delivers roughly 30–40% lower maintenance and transport cost over a 10 000-hour horizon, primarily due to 9× faster shaft swaps, 25% longer service intervals, and a 19% lower operating weight class that eliminates heavy-haul permits on most European corridors.

Which machine is better for contaminated construction and demolition waste?

The ARJES Impaktor 1100. Its 350 000 Nm cutting-torque reserve (25% higher than the Atlas Copco ST 1000) translates directly into fewer stall events and faster recovery on feedstock with embedded rebar, concrete chunks, and steel brackets — the real-world norm for C&D recycling yards.
