About Best Construction Machinery Parts International Ltd. - Electric Motors Supplier in China

Based in China, Best Construction Machinery Parts International Ltd. currently lists seven active products across its catalogue. The product set includes a Case CX210 travel motor, a Komatsu Pc220‑7/Pc240‑8 swing gearbox, a Hitachi Zx330‑3 travel gearbox, a Komatsu Pc40/pc45/pc50/pc55 hydraulic pump, generic hydraulic pump parts, a complete Isuzu engine and engine parts, and general construction machinery parts. The engine and engine parts are classified under HS code 8409.99 and are manufactured from cast iron, aluminum alloy and forged steel depending on the component. The broader construction machinery parts fall under HS code 8431.49 and are produced from alloy steel or high‑strength cast iron of grades G3500 and G4000. The remaining items are categorized within the broader HS chapters for electric motors, gearboxes and hydraulic equipment.

These offerings span the primary categories of electric motors, excavator spare parts, industrial gears and gearboxes, hydraulic equipment, automobile engines and construction equipment spare parts. Each listing aligns with the supplier’s top categories such as Electric Motors, Excavator Machines and Spare Parts, Industrial Gears & Gear Boxes, Hydraulic Equipments, Spare Parts - Household Pumps, Automobile Engines and Construction Equipment Spare Parts. The catalogue does not provide additional HS codes for the travel motor, gearboxes or hydraulic pumps, which are typically recorded under HS chapters 84 (machinery) and 84.71 (gearboxes). Material specifications range from forged steel for gear components to cast iron for pump housings. The supplier’s portfolio therefore reflects a focus on heavy‑duty components used in construction and mining machinery.

Product Range and Specialties of Best Construction Machinery Parts International Ltd.

The catalogue lists a Case CX210 travel motor, a Komatsu swing gearbox for Pc220‑7 and Pc240‑8 models, a Hitachi Zx330‑3 travel gearbox, Komatsu series hydraulic pumps (Pc40 to Pc55), assorted hydraulic pump parts, complete Isuzu diesel engines with parts, and generic construction machinery parts. Travel motors for construction equipment are commonly rated to IEC 60034 standards, with typical power outputs between 15 kW and 45 kW and insulation classes F or H. Swing gearboxes and travel gearboxes for excavators usually conform to ISO 6336 strength testing and are offered in ISO 630 gear tooth profiles, with gear ratios ranging from 10:1 to 30:1.

Hydraulic pumps for excavators are generally designed to meet ISO 1219 pressure‑velocity diagrams and operate at flow rates of 30 L/min to 250 L/min, with pressures up to 350 bar. Diesel engines for construction vehicles are typically built to meet emission standards such as Euro IV or EPA Tier 4, and are cast in high‑strength iron or aluminum alloy blocks to achieve power ratings from 120 kW to 350 kW. Construction machinery parts made from alloy steel grades G3500/G4000 are intended to satisfy the tensile strength requirements of ISO 683‑1, ensuring durability under cyclic loading.

Trade and Export Information - Best Construction Machinery Parts International Ltd.

China is a leading exporter of construction equipment components, with major destinations in Southeast Asia, the Middle East, Africa and Latin America. HS code 8409.99 for engines and engine parts and HS code 8431.49 for other machinery parts are routinely inspected under the Shanghai Inspection and Quarantine (CIQ) regime, and buyers often require a Certificate of Origin and a commercial invoice referencing the correct HS classification. Common certifications requested by overseas importers include ISO 9001 quality management, ISO 14001 environmental management and, where applicable, CE marking for equipment entering the EU market.

Typical shipment methods involve 20‑foot or 40‑foot containers packed on wooden pallets with steel strapping, or bulk shipments on open‑top containers for oversized gearboxes. Incoterms such as FOB Shanghai or CIF Dubai are frequently used, with buyers specifying moisture content limits for hydraulic pump parts (usually below 0.5 %). Export documentation often includes a test report confirming compliance with ISO 6336 for gearboxes or ISO 1219 for hydraulic pumps, as well as material certificates for alloy steel components.

Sourcing from Best Construction Machinery Parts International Ltd. - Buyer Guidance

Purchasers should request the latest ISO test reports for gearboxes and hydraulic pumps, as well as engine performance data that includes power output, torque curves and emission test results. Material certificates confirming the alloy steel grade (G3500 or G4000) or cast iron composition should be reviewed before confirming orders. For the Case travel motor, buyers normally verify IEC 60034 compliance, insulation class and voltage rating.

Sample units are typically offered on a prepaid basis, allowing inspection of weld quality, surface finish and dimensional tolerances. Minimum order quantities for bulk components such as hydraulic pumps often start at one full 20‑foot container (approximately 12‑15 units depending on size). Lead times reported by Chinese manufacturers for these items range from 30 to 60 days after order confirmation, subject to production scheduling and export clearance.

What product categories does the supplier offer?

The supplier lists electric travel motors, swing and travel gearboxes for excavators, hydraulic pumps and pump parts, complete Isuzu diesel engines with parts, and general construction machinery components. These items cover the categories of Electric Motors, Excavator Spare Parts, Industrial Gears & Gear Boxes, Hydraulic Equipments, Automobile Engines and Construction Equipment Spare Parts.

Which HS codes apply to the engine and construction parts?

The Isuzu engine and engine parts are classified under HS code 8409.99. The broader construction machinery parts fall under HS code 8431.49. Both codes are part of the HS chapter for machinery and equipment.

What certifications should a buyer request for these items?

Buyers should ask for ISO 9001 quality management certificates and ISO 14001 environmental certificates. For equipment destined for the EU, a CE conformity declaration is typical, and specific test reports such as ISO 6336 for gearboxes, ISO 1219 for hydraulic pumps and IEC 60034 for motors are commonly required.

What are typical material specifications for the gearboxes and construction parts?

Gearboxes are generally fabricated from forged steel or alloy steel, while the construction machinery parts are made from alloy steel grades G3500 or G4000 or high‑strength cast iron. These materials meet the tensile strength requirements of ISO 683‑1 for heavy‑duty applications.

What are common packaging and shipping methods?

Items are usually packed on wooden pallets with steel strapping inside 20‑ft or 40‑ft containers. Oversized gearboxes may be shipped in open‑top containers, and Incoterms such as FOB Shanghai or CIF to the destination port are typical.

What is the usual lead time and minimum order quantity?

Lead times are typically 30‑60 days after order confirmation. Minimum orders often start at one full 20‑ft container for bulk components, although smaller quantities can be arranged for sample units.

How can a buyer verify compliance before shipment?

Buyers should obtain the relevant ISO test reports, material certificates, and a Certificate of Origin for each product. A third‑party inspection report from CIQ or an independent inspection agency can provide additional assurance prior to loading.
