About Guiyang Sunpoc Machinery & Equipment Co., Ltd. - Excavator Machines, Excavator Spare Parts Supplier in China

Guiyang Sunpoc Machinery & Equipment Co., Ltd. is based in China and currently lists five active products in its catalogue. The supplier is classified as an imported, harbor‑tier source, indicating a moderate level of verification. Its catalogue focuses on excavator machines and spare parts, specifically components used on hydraulic excavators. The listed items include an excavator three‑segment boom, a grab bucket, a hydraulic cylinder, a standard boom, and a rock bucket. These products fall under the heavy machinery segment commonly recorded under HS chapter 84 for machines and mechanical appliances.

The three‑segment boom and standard boom are structural steel members that connect the house to the arm, typically fabricated from Q235 or Q345 steel with welding conforming to ISO 12944 for corrosion protection. Grab and rock buckets are forged cast‑iron or steel attachments, often rated by bucket capacity in cubic meters and edge strength measured in MPa. Hydraulic cylinders are pressure vessels that usually operate at 200 - 350 bar and are supplied with rod and seal specifications matching ISO 6020. Buyers of these components generally require detailed technical drawings, load‑rating certificates, and compliance with safety standards such as ISO 12100.

Product Range and Specialties of Guiyang Sunpoc Machinery & Equipment Co., Ltd.

The catalogue offers five distinct excavator accessories. The three‑segment boom and standard boom provide reach extensions ranging from 6 m to 12 m, with mounting points compatible with common excavator brands. The grab bucket is designed for material handling and typically features a bite width of 300 - 600 mm and a hydraulic closing force of 30 - 80 kN. The rock bucket is reinforced for hard‑rock excavation, with wear‑resistant steel and a capacity of 0.4 - 1.0 m³. The hydraulic cylinder is supplied in bore diameters from 50 mm to 150 mm, rated for pressures up to 350 bar, and includes standard rod seals.

In the global excavator market, booms are classified by segment count and load rating, with ISO 12100 and ANSI/SAE J1349 often referenced for safety and performance. Buckets are graded by material hardness (e.g., HRC 40 - 45 for rock buckets) and may carry CE marking for EU imports. Hydraulic cylinders are subject to ISO 4427 for fluid‑power equipment, and buyers frequently request test reports confirming pressure‑holding and leakage limits. These specifications help buyers compare components across manufacturers.

Trade and Export Information - Guiyang Sunpoc Machinery & Equipment Co., Ltd.

China is a major exporter of heavy construction equipment and related spare parts, with the majority of shipments destined for Asia, the Middle East, Africa, and Latin America. Excavator components are classified under HS chapter 84, and shipments are typically packed in wooden crates or steel frames to protect the steel structures during sea freight. Common Incoterms used by Chinese machinery exporters include FOB Shanghai or CIF Dubai, allowing buyers to arrange inland transport or receive door‑to‑door service. Buyers usually request certificates such as ISO 9001 for quality management, CE conformity for EU markets, and a test report from an accredited inspection body like SGS or Bureau Veritas.

Export licensing for heavy machinery in China requires compliance with the Ministry of Commerce’s export control catalogue, and certain high‑pressure hydraulic components may be subject to additional safety documentation. Importers often arrange pre‑shipment inspection under the buyer’s chosen inspection company to verify dimensions, weight (typically 1 800 kg to 3 000 kg per boom), and material certificates. Container loading commonly uses 20‑foot or 40‑foot containers with a net weight limit of 22 t, and freight forwarders advise on crate dimensions to maximize space utilization.

Sourcing from Guiyang Sunpoc Machinery & Equipment Co., Ltd. - Buyer Guidance

When sourcing from Guiyang Sunpoc, buyers should request detailed product datasheets that list material grade, dimensions, hydraulic pressure rating, and load‑capacity certifications. It is advisable to obtain an ISO 9001 certificate copy and a recent third‑party test report confirming compliance with ISO 12100 safety standards. Samples or photographs of the finished boom or bucket can be requested before final order to verify surface finish and welding quality. Typical minimum order quantities are one unit per product type, with lead times reported between 30 and 60 days after order confirmation, subject to production scheduling.

What types of excavator components does Guiyang Sunpoc list in its catalogue?

The supplier lists five items: an excavator three‑segment boom, a standard boom, a grab bucket, a rock bucket, and a hydraulic cylinder for excavators. Each item is presented as a separate product entry in the catalogue.

Which standards or certifications should a buyer verify for these excavator parts?

Buyers should request the supplier’s ISO 9001 quality‑management certificate, CE conformity documentation if exporting to the EU, and test reports that reference ISO 12100 for safety and ISO 4427 for hydraulic cylinders. These documents provide evidence of compliance with common international requirements.

What are the typical dimensions or capacities for the grab and rock buckets offered?

Grab buckets generally have a bite width of 300 - 600 mm and a closing force of 30 - 80 kN, while rock buckets are reinforced for hard material and typically hold 0.4 - 1.0 m³ of material. The specifications may vary slightly depending on the specific model selected.

How are the booms packaged for international shipment?

Booms are usually crated in reinforced wooden boxes with internal bracing to prevent deformation during transit. The crates are then loaded into 20‑foot or 40‑foot containers according to weight limits of approximately 1 800 - 3 000 kg per boom.

What Incoterms are commonly used for exporting these heavy‑machinery components from China?

Exporters often quote FOB Shanghai or CIF Dubai, allowing the buyer to arrange inland transport or receive the goods delivered to the destination port. These terms are standard for large, heavy equipment shipments.

What documentation is typically required before placing an order?

Buyers should obtain product data sheets, material certification (e.g., steel grade certificates), the supplier’s ISO 9001 copy, and a third‑party inspection report confirming dimensions and pressure ratings. Having these documents helps verify that the components meet the buyer’s technical requirements.

What is the usual lead time and minimum order quantity for a single excavator component?

Lead times are usually 30 - 60 days after order confirmation, depending on production scheduling and stock availability. The minimum order quantity is typically one unit per product type, unless the buyer arranges a bulk purchase.
