Every week your machine sits without its undercarriage, your project loses money. That's why delivery time matters as much as product quality for overseas buyers.
But "fast delivery" means different things depending on where you are. A Chinese supplier might quote 7 to 15 days for a standard steel track undercarriage. That timeline usually starts after the drawings are approved, not after you send the inquiry. The engineering phase - confirming dimensions, mounting points, and drive specifications - can take additional days before production begins.
For custom units, the timeline stretches. If the undercarriage requires FEM calculations for a non-standard load distribution, the engineering stage alone may take a week or more. This isn't delay; it's what prevents a structural failure after delivery.
The practical approach for buyers with tight schedules: ask for a production schedule with named milestones. "15 days" should break down into drawing approval, material preparation, welding, assembly, testing, and packing. A supplier who can provide this breakdown understands that your undercarriage isn't just a product - it's a link in your project chain.
One more thing worth asking: what happens if the shipment misses the vessel? A supplier with experience in your region will have dealt with this before and can tell you their actual track record, not just their optimistic estimate.
