ZE485E‑10‑5175 — Built 2021 | 1,410 hrs | Fitted with Aidi (艾迪) 195 hydraulic breaker

Summary

• Model/ID: ZE485E‑10‑5175
• Year: 2021
• Hours: 1,410 (relatively low overall)
• Attachment: Aidi 195 breaker — must verify breaker hours/use separate from carrier hours

Key strengths

• Low carrier hours — less general wear if maintenance was good.
• Breaker on-board is valuable for demolition/secondary breaking work if it is in good condition and properly matched.

Primary concerns to verify

• Breaker usage may far exceed carrier hours (ask for separate breaker service hours or impact counts).
• Verify hydraulic compatibility: carrier pump flow and system pressure vs breaker requirements. Under- or over‑supply damages both breaker and carrier hydraulics.
• Breaker condition: chisel wear, retaining pins, internal wear (piston, valve), nitrogen chamber pressure (if applicable), hose condition and quick coupler integrity.
• Structural stress at mounting points and boom/arm where breaker transmits high impact loads — check for cracks/weld repairs.

Essential pre‑purchase checks (must do)

1. Documentation

   • Machine VIN/engine/serial numbers, full service & repair records for both carrier and breaker, any accident/flood history, lien status.

2. Photos & videos to request now

   • Breaker: overall, chisel/point, mounting flange, serial plate, hose connections, nitrogen valve/port.
   • Machine: engine bay, hydraulic tank sight, boom/arm pins, mounting interface, undercarriage, swing bearing, cab, hour meter.
   • Videos: cold start, idle, hydraulic functions (boom/arm/swing/travel), and an on‑site live breaking demo (breaker hitting concrete/stone) showing rhythm, power and sounds.

3. On‑site functional tests

   • Cold and hot start; observe smoke, idling and running noises.
   • Run breaker under load for several minutes: watch oil temp, breaker rhythm, carrier pump noise, any cavitation or loss of power.
   • Check for hydraulic leaks, cylinder rod damage and play in pins/bushings.

4. Fluid & lab tests (strongly recommended)

   • Send engine oil, hydraulic oil and final drive oil for lab analysis (wear metals, water, fuel dilution).

5. Structural & mechanical

   • Inspect boom/arm mounting for cracks, welds or deformation. Measure pin/bushing play. Check undercarriage and final drives.

Red flags (walk away or demand large discount)

• Breaker fails to deliver expected strikes or loses rhythm under load; loud internal knocking from breaker.
• Nitrogen chamber leaks, frequent need to re‑pressurize.
• Significant metal in oil samples, severe pump cavitation or gas/foam in hydraulic oil.
• Cracks/welds at breaker mount, boom or arm; severe pin/bushing play.
• Missing service records or seller cannot show live breaking demo.

Recommended next steps

• Ask seller for immediate: breaker serial/ID, breaker operating hours, maintenance records, photos/videos listed above, and the reason for selling.
• Arrange an independent on‑site inspection that includes a live breaker test, hydraulic pressure/flow checks and oil sampling.
• If inspection acceptable, get repair/part quotes (chisel, seals, nitrogen service, hydraulic hose replacement) and factor into negotiation.
