从China供应商批量进口500kg Hand Winch Strap

The 500kg Hand Winch Strap from Ningbo S&D Metal Work Co.,Ltd is a load-securing device rated for 500……kg maximum working load, designed for manual tensioning and holding applications in industrial environments. The strap measures 50mm in width and 7 metres in length, dimensions that suit medium-duty cargo restraint and machinery positioning tasks. A Dacromet coating covers the metal components, providing a zinc-aluminium chromate finish recognised for salt-spray corrosion resistance in marine and outdoor settings. The mechanism incorporates a three-speed gear train with a 3:1 mechanical advantage, reducing operator effort during load pulling or tightening operations. Universal mounting holes are machined into the housing, enabling bolted or pinned attachment to frames, trailers, or fixed structures without custom fabrication. The handle remains stationary during drum rotation, a design that improves control and reduces fatigue during repetitive use.

Dacromet is a standard thin-film coating process in the lifting hardware industry, typically delivering 500 - 1000 hours of neutral salt-spray resistance per ASTM B117, though the supplier does not publish test data for this specific lot. The 50mm webbing width aligns with common ratchet and winch strap standards, allowing interchangeability with ISO 4878 or EN 12195-2 compliant accessories. The 7 metre length provides practical reach for box-truck load beds and small vessel decks. Buyers should confirm whether the webbing is polyester, polypropylene, or another synthetic, as this affects UV stability and elongation under load. The gear housing material and exact tooth count are not stated; cast or forged steel is typical for this load class. No information is given on webbing breaking strength, stitch pattern, or tag colour coding for load-rating visibility.

Primary applications include construction site material handling, manufacturing plant equipment positioning, logistics freight securing, and agricultural machinery transport. The 500kg rating positions this unit below heavy-lifting winches but above light-duty tie-downs, suiting small contractors and fleet operators who need portable, non-powered tensioning. Ningbo S&D Metal Work Co.,Ltd is located in Zhejiang Province, a region with established metalwork and hardware manufacturing clusters. The supplier lists no response data or verification documentation, so buyers should request current mill certificates, coating thickness reports, and webbing batch test results before committing. Incoterms, exact MOQ, and lead time are not disclosed and must be confirmed directly with the supplier.

Ningbo S&D Metal Work Co.,Ltd is registered at No.691-1, Tiantong, Dongwu, Ningbo 315000, Zhejiang Province, China. The company operates within the Ningbo metropolitan area, a manufacturing hub known for hardware, metal castings, and marine equipment supply chains. The supplier's tier is classified as imported, and its trust tier is harbour, indicating a basic marketplace presence without advanced verification or transaction history displayed. The response rate is recorded at 0.00 percent with zero average response hours, which suggests either a new listing, inactive account, or unmonitored inquiry channel rather than a closed business.

The listing provides no information about factory size, number of employees, annual output, ownership structure, or years in operation. No client references, export licences, or industry memberships are mentioned. Buyers should therefore conduct standard due diligence, including requesting a business licence copy, factory audit report, and sample order before bulk commitment. The product focus appears to be manual winch hardware and associated load-securing equipment, with Dacromet finishing as a marketed feature. The absence of ISO or CE certification references in the source data means any such claims must be verified with current, scope-matched certificates from the supplier directly.
