Verdict

Advantage

Asynchronous hydrostatic delivers 700% more torque — significantly attenuated shock loads to drivetrain

The Metso LT120 routes power through a fixed-ratio mechanical gearbox.
Torque is a function of gear ratio and engine RPM — no dynamic adaptation.
When a contaminant jams a shaft, the full shock pulse transmits through the gear-mesh into the engine block.
ARJES Impaktor 1250 D decouples shafts via asynchronous hydrostatic motors: each shaft runs independently with 177,015 lb-ft of sustained cutting torque — 700% above the Metso's 22,127 lb-ft.
Hydrostatic circuits absorb energy spikes; the opposite shaft continues uninterrupted.
Result: fewer stalls, faster cycle recovery, reduced gear-mesh fatigue exposure under ARJ-TRQ-2026 protocol.

Advantage

Maintenance cycle favors ARJES: 2h swap vs 8h Metso intervention

The Metso LT120 requires 8 hours per shaft/tool maintenance event.
ARJES Impaktor 1250 D completes Quick-Change Cassette swap in 2 hours — no welding, bearing pull, or alignment checks.
Combined with 500 h ARJES service interval vs 500 h for Metso, the scheduled maintenance burden is measurably lower.

Advantage

56,218 lb breaches EU 40 t GVW — permits, escorts, low-boy every move

The Metso LT120 at 56,218 lb exceeds the 24 t threshold for standard hook-lift/flatbed within EU 40 t GVW.
Every relocation requires low-boy, heavy-haul permit (3–14 day lead), and often pilot escort.
Per-move cost: $1,620–3000 on top of standard $864–1200.
ARJES Impaktor 1250 D at 81,571 lb stays within standard transport class — hook-lift, zero permits, same-day relocation.
For 10–20 moves/year, this saves $16,200–60000 annually.

Frequently Asked Questions

Is the ARJES Impaktor 1250 D directly comparable to the Metso LT120?

They are both mobile primary reduction machines but use different reduction principles: the Impaktor 1250 D is a low-speed twin-shaft hydrostatic shredder (400 kW, 240 000 Nm), the Metso LT120 is a high-speed single-toggle jaw crusher (90 kW). They are commonly shortlisted together for high-volume C&D recycling yards where feedstock flexibility matters.

Which machine can process reinforced concrete with steel rebar?

The ARJES Impaktor 1250 D. Its 240 000 Nm low-speed twin-shaft geometry tolerates embedded rebar and recovers automatically from tramp-metal stalls. The Metso LT120 jaw crusher requires labor-intensive rebar pre-stripping; running rebar through the jaw causes blockage, jaw-plate cracking, and warranty-voiding damage.

Which machine is better for clean concrete and asphalt recycling?

For quarries and contractors processing 100% clean concrete and asphalt with rebar pre-stripped, the Metso LT120 delivers 25–80% more throughput per hour at lower CAPEX. For mixed C&D yards handling wood, steel, and debris alongside concrete, the ARJES Impaktor 1250 D eliminates pre-sorting labor and unlocks 5 material families from a single machine.
