About KSC Construction Machinery Co., Ltd. - Excavator Machines, Excavator Spare Parts Supplier in China

KSC Construction Machinery Co., Ltd. is based in China and lists five active product entries in its catalogue. The company focuses on excavator machines and heavy machinery components, specifically offering excavator spare parts, excavator buckets, Komatsu undercarriage parts, Komatsu parts, and excavator pins and bushings. Each product type aligns with standard HS chapter 84 machinery and equipment, where excavator parts are typically classified under sub‑heading 8429. The catalogue reflects a narrow but targeted range of components used in large earth‑moving equipment.

The listed items serve OEM and aftermarket markets for brands such as Komatsu, covering wear‑resistant steel buckets, hydraulic pins, and undercarriage rollers. Buyers can expect material specifications such as high‑strength alloy steel (e.g., AISI 4340) for pins and bushings, and heat‑treated cast iron for buckets, which meet typical industry tolerances of ±0.2 mm on critical dimensions. The product set is designed for compatibility with excavator models ranging from 20 ton to 60 ton class machines. The supplier’s catalogue does not include additional accessory lines beyond these five components.

Product Range and Specialties of KSC Construction Machinery Co., Ltd.

The catalogue enumerates five concrete items: excavator spare parts, excavator bucket, Komatsu undercarriage parts, Komatsu parts, and excavator pin and bushing. In the excavator market, spare‑part categories are usually graded by wear resistance, material hardness (often 45‑55 HRC for pins) and compliance with OEM part numbers. Buckets are typically manufactured from high‑strength forged steel meeting ISO 9001 quality management and may carry surface treatments such as wear‑resistant plating or heat‑treated hardening.

Industry practice for undercarriage components includes using cast steel or forged alloy that conforms to ISO 14001 environmental management where manufacturers seek low wear rates. Komatsu‑specific parts often follow the OEM’s technical specification sheets, which define dimensional tolerances, bolt thread standards (M12‑1.5, M16‑1.5) and required load ratings. Buyers generally compare these specifications against the supplier’s data sheets to confirm interchangeability.

Trade and Export Information - KSC Construction Machinery Co., Ltd.

China remains a major exporter of excavator components, supplying to construction markets in Southeast Asia, the Middle East, Africa and Latin America. HS sub‑heading 8429.99 typically covers excavator parts, and customs authorities in importing countries often request material test reports and conformity declarations for steel grade and heat‑treatment processes. Standard export packaging includes wooden pallets, shrink‑wrapped bundles, and 20‑ft or 40‑ft containers, with freight terms most commonly quoted as FOB Shanghai or CIF destination port.

Typical buyers request CE marking or ISO 9001 certification to satisfy local regulatory requirements, especially for public‑sector projects. Chinese manufacturers frequently employ quality‑inspection agencies to perform pre‑shipment checks, and buyers may ask for a pre‑shipment inspection (PSI) report referencing the relevant HS code. Lead times for bulk orders of standard parts range from 30 to 45 days, while custom‑spec buckets can extend to 60 days.

Sourcing from KSC Construction Machinery Co., Ltd. - Buyer Guidance

When sourcing from KSC, request the material test certificate (MTC) that specifies chemical composition and hardness for each steel component. Verify that the part numbers match the OEM catalogues for the target excavator model and ask for a dimensional drawing to confirm fitment tolerances. It is prudent to ask for a copy of any ISO 9001 or CE conformity documentation the supplier can provide, even if not listed in the catalogue, to satisfy typical import compliance checks.

Sample orders of small‑size pins or bushings are often accepted in a 1 kg quantity, packed in anti‑corrosion bags. For larger items such as buckets, buyers usually arrange a trial shipment on a 20‑ft container to evaluate surface finish and dimensional accuracy before committing to larger volumes. Confirm packaging details - e.g., wood pallet dimensions, edge protection, and moisture barrier - to avoid damage during sea freight.

What excavator components are listed in KSC’s catalogue?

The catalogue lists five items: excavator spare parts, excavator bucket, Komatsu undercarriage parts, Komatsu parts, and excavator pin and bushing.

Are the excavator buckets compatible with specific machine brands?

The buckets are manufactured to match standard Komatsu and other major excavator mounting dimensions. Buyers should compare the bucket mounting width and hydraulic pin spacing with the target model’s specifications.

Which certifications should a buyer request from KSC?

Buyers typically request ISO 9001 quality‑management certification, CE conformity declarations, and material test certificates for steel grade and hardness. These documents are standard for heavy‑machinery components.

What is the usual minimum order quantity for excavator pins?

A common MOQ for pins and bushings is 100 pieces per size, though smaller trial quantities of 10‑20 pieces can be arranged for sample evaluation.

How are the parts packaged for export?

Parts are usually shrink‑wrapped and placed on standard 1200 mm × 1000 mm wooden pallets. Larger items such as buckets are secured with steel strapping and loaded into 20‑ft or 40‑ft containers.

What lead time can a buyer expect for Komatsu undercarriage parts?

Standard undercarriage components are typically produced and ready for shipment within 30‑45 days after order confirmation. Custom‑specifications may require up to 60 days.

Which HS code is relevant for the excavator spare parts?

Excavator spare parts are generally classified under HS sub‑heading 8429.99, which covers parts and accessories of machinery for earth‑moving.

How can a buyer obtain technical drawings for KSC’s parts?

Buyers should request a CAD or PDF drawing from the supplier, referencing the specific part number. The supplier can provide dimensional schematics that detail bolt patterns, pin diameters and mounting interfaces.
