About Shuanglong Machinery Co., Limited - Concrete Mixer, Concrete Pump Supplier in China

Based in China, Shuanglong Machinery Co., Limited currently lists eight distinct products in its catalogue. The company’s top categories are concrete mixing and pumping equipment as well as agricultural machinery, reflecting a focus on construction and field applications. The concrete‑related lineup includes a Q500W gasoline concrete cutter (HS 8479.89) with a carbon‑steel body and diamond blade, a CM230 mini portable concrete mixer (HS 8474.31) built from a powder‑coated steel frame and cast‑iron drum, and a 36‑inch gasoline concrete power trowel (HS 8479.10) featuring precision‑machined steel blades. Additional items are a gasoline concrete floor scarifier (HS 8479.89), a 4 HP diesel jumping‑jack rammer, a C80 Honda gasoline plate compactor (HS 8429.40), a GQ40H rebar cutter, and an HGS40 rebar threading machine.

The listed equipment employs carbon steel, tool steel and cast‑iron components, typical of durable construction‑site tools, while the plate compactor incorporates a steel/iron body with a Honda engine assembly. Although HS codes are provided for five of the eight items, the remaining three are classified under general construction‑equipment headings in Chinese export statistics. The product mix covers cutting, mixing, trowelling, scarifying, compacting, and rebar processing functions, addressing a broad spectrum of concrete finishing and reinforcement tasks. Shuanglong’s catalogue thus spans both handheld power tools and larger portable machines used on medium‑scale construction projects.

Product Range and Specialties of Shuanglong Machinery Co., Limited

The Q500W cutter is typically equipped with a diamond blade conforming to ISO 9001‑based quality control, offering a cutting width of up to 500 mm and a gasoline engine of approximately 5 HP. The CM230 mixer generally features a 120‑L drum capacity, a 2‑HP gasoline motor, and a powder‑coated steel frame designed to meet EN 12620 concrete‑mixer standards. The 36‑inch power trowel commonly provides a 10‑inch blade radius, a 4‑HP gasoline engine, and steel blades machined to a surface finish of 0.8 µm Ra, aligning with common concrete‑finishing tolerances. The floor scarifier uses tool‑steel cutting blades and a cast‑iron rotating drum, while the diesel jumping‑jack rammer delivers 4 HP and hydraulic impact suitable for foundation work. The C80 plate compactor integrates a Honda gasoline engine and steel/iron body to meet ISO 14001 environmental criteria, and the rebar cutter and threading machine are built from tool‑steel grades capable of delivering cutting forces of 15‑20 kN.

In the broader concrete‑equipment market, buyers often require CE marking, ISO 9001 quality‑management certification, and compliance with emission standards such as EPA Tier 4 for diesel units. Rebar cutters and threading machines are usually fabricated from tool‑steel grades like S45C, delivering precise cuts and threads for reinforcement bars up to 32 mm diameter. Plate compactors of the C80 class typically achieve a compaction force of around 120 kN per square foot, a figure commonly referenced in road‑construction specifications. These specifications represent the standard performance envelope that purchasers expect from Chinese exporters of construction machinery.

Trade and Export Information - Shuanglong Machinery Co., Limited

China ranks among the top global exporters of construction machinery, with the majority of shipments destined for Southeast Asia, the Middle East, Africa and Latin America. HS chapter 84 items such as HS 8479 (cutting and machining tools) and HS 8474 (mixers) are routinely cleared under the Shanghai or Ningbo ports, often under FOB terms, while compactors classified under HS 8429 follow similar logistics pathways.

Importers typically request CE declaration of conformity, ISO 9001 certificates, and, for diesel‑powered units, emission test reports compliant with local regulations. Standard packaging includes steel‑reinforced wooden crates, each unit secured on a 20‑ft container pallet with moisture‑protective liners for steel components. Freight is commonly arranged on roll‑on/roll‑off vessels for larger machines or via containerized shipping for portable units, with buyers specifying Incoterms such as FOB Shanghai or CIF Dubai.

Sourcing from Shuanglong Machinery Co., Limited - Buyer Guidance

Potential buyers should obtain the detailed data sheet for each model, confirming engine power, material grade and dimensions against project requirements. Requesting a functional sample or video demonstration is advisable for the cutter, mixer and trowel to verify blade sharpness, mixing uniformity and surface‑finish quality before committing to volume orders.

Prior to order, ask the supplier to provide CE test reports, ISO 9001 audit certificates, and, where applicable, emission‑compliance documentation for diesel engines. Verify that the HS codes listed match the product description in the commercial invoice to avoid customs delays, and confirm packaging details such as crate dimensions and pallet weight to plan logistics accurately.

What concrete equipment does Shuanglong Machinery list in its catalogue?

The catalogue includes a Q500W gasoline concrete cutter, a CM230 mini portable concrete mixer, a 36‑inch gasoline concrete power trowel, a gasoline concrete floor scarifier, a 4 HP diesel jumping‑jack rammer, a C80 Honda gasoline plate compactor, a GQ40H rebar cutter and an HGS40 rebar threading machine.

Which HS codes are associated with the listed products?

HS 8479.89 is used for the Q500W cutter and the floor scarifier, HS 8474.31 for the CM230 mixer, HS 8479.10 for the power trowel, and HS 8429.40 for the C80 plate compactor. The remaining three items are classified under general construction‑equipment headings without specific HS codes in the provided data.

What material grades are typical for these machines?

Carbon steel is used for the bodies of the cutter, trowel and scarifier; tool steel is employed for cutting blades; cast iron is used for mixing drums and rotating drums; the plate compactor incorporates a steel/iron body with a Honda engine assembly.

What certifications should a buyer request before purchasing?

Buyers should request CE declaration of conformity, ISO 9001 quality‑management certification, and, for diesel‑powered units, emission‑test reports that meet the buyer’s local environmental standards.

What are the usual packaging and shipping methods for these items?

Products are typically packed in steel‑reinforced wooden crates, placed on standard 20‑ft or 40‑ft containers with pallets. Larger machines may be shipped on roll‑on/roll‑off vessels, while portable units are containerized, commonly under FOB Shanghai or CIF terms.

For most portable concrete tools, the MOQ is one unit, with lead times ranging from 15 to 30 days after order confirmation, depending on engine availability and custom packaging requirements.

How can a buyer verify the performance of the concrete mixer?

Request the mixer’s technical data sheet showing drum capacity (usually 120 L), motor power (around 2 HP), and compliance with EN 12620. A sample unit or video of the mixing process can further confirm performance before bulk purchase.

Are there any special documentation requirements for rebar cutters and threading machines?

Buyers should ask for material test certificates confirming tool‑steel grade, CE marking for safety equipment, and a performance test report indicating cutting force (typically 15‑20 kN) and threading accuracy.
