Q
How do you guarantee the operational condition of a used excavator before shipment?
AEvery machine undergoes a rigorous multi-point inspection covering the engine performance, hydraulic pressure, swing mechanism, and undercarriage integrity to ensure it arrives job-site ready. We provide comprehensive inspection reports and high-definition operation videos for every unit, and we also welcome third-party inspections from recognized agencies like SGS to verify the equipment's condition on your behalf.
-
Q
Are the used excavators original units and how do you verify their working hours?
AWe specialize in authentic, high-quality machinery from leading global brands such as Caterpillar, Komatsu, and SANY, ensuring that every unit has a verifiable service history and no structural damage. Our policy strictly prohibits meter tampering, so the working hours displayed are genuine reflections of the machine's usage, allowing you to make an informed decision based on true mechanical wear.
-
Q
What kind of after-sales support and spare parts availability do you offer for international buyers?
ATo minimize your downtime, we provide lifetime technical support via video consultation and maintain a robust inventory of genuine spare parts available for immediate global dispatch. We often include a complimentary kit of essential wear parts like filters and seals with your initial purchase and offer long-term sourcing assistance for any specialized components your project might require.

What measures are taken to protect the machinery during international maritime transport?
AOur logistics team utilizes professional heavy-duty lashing, anti-rust coating treatments, and secure containerization or Ro-Ro shipping methods to safeguard the machine against salt spray and physical impact. We manage the entire export documentation process and provide comprehensive cargo insurance for every shipment to ensure your investment is fully protected from the departure port to your final destination.

Q
What are your standard payment terms and how long does the delivery process typically take?
AOur standard trading terms usually involve a 30% deposit to secure the unit with the remaining balance due before loading, ensuring a transparent and secure transaction for both parties.
