Duplex pulley
The duplex pulley offered by Ningbo Yunhai Metal & Rigging Co.Ltd is an industrial‑grade lifting component designed for heavy‑load applications. It features a duplex construction that distributes load evenly across two sheaves, reducing wear on the rope. The supplier describes the pulley as having a high weight capacity suitable for demanding environments. Precision‑engineered components and a user‑friendly mounting design enable quick installation on existing rigging systems.
Typical duplex pulleys are forged from medium‑carbon steel and receive a heat‑treated finish that provides a hardness of around 45 HRC, which is standard for this class of equipment. Industry practice sets the allowable load rating between 5 tonnes and 15 tonnes, with a safety factor of at least 5:1, which buyers should verify for each model. Standard rope groove diameters range from 12 mm to 32 mm, allowing compatibility with common steel wire ropes. A powder‑coat or galvanised outer layer is typical to improve corrosion resistance in outdoor settings.
The pulley is commonly used in construction hoists, manufacturing line lifts and warehouse pallet‑stacking systems. Buyers such as contractors, equipment distributors and logistics firms often request ISO 9001 and CE certificates, which the supplier states are available. Trade terms can be negotiated as FOB or CIF, and the pulleys are packed in reinforced wooden crates to survive sea freight. Minimum order quantities are flexible, but exact figures should be confirmed directly with Ningbo Yunhai Metal & Rigging Co.Ltd.

Sourcing Duplex pulley from Ningbo Yunhai Metal & Rigging Co.Ltd - China Import Guide
Before placing an order, verify the pulley’s load rating, material grade and dimensional tolerances by requesting the latest test report and a CAD drawing if available. Confirm that the ISO 9001 and CE certificates are current and correspond to the specific model you intend to purchase.
Shipping from Ningbo typically follows FOB or CIF terms; discuss the preferred Incoterm, expected lead time and payment conditions with the supplier. Because response metrics are not recorded, maintain clear written communication to avoid misunderstandings about delivery schedules and documentation requirements.
Quality assurance should include visual inspection for surface defects, verification of the heat‑treated hardness and a load test if feasible. Engaging a third‑party inspection agency to review the mill test certificate and perform on‑site checks before loading can reduce the risk of non‑conformity.
