从China供应商批量进口700kg Hand Winch Strap

The 700kg Hand Winch Strap from Ningbo S&D Metal Work Co.,Ltd is a manual lifting device rated for a 700 kilogramme working load limit, manufactured with a 50 millimetre wide strap measuring 8 metres in length. The strap body receives a Dacromet coating, a zinc-flake finish that provides corrosion resistance in humid or salt-exposed environments without the hydrogen embrittlement risk of conventional galvanising. A three-speed gear system operates at ratios of 5:1 and 1:1, allowing the operator to select mechanical advantage for hoisting or rapid payout. Universal mounting holes are drilled into the frame for bolting to flat surfaces, vehicle beds, or temporary rigging points. The handle is removable, reducing the packed volume for transport and storage. This configuration targets construction crews, marine operators, and agricultural equipment handlers who need portable, non-powered lifting without hydraulic or electrical dependency.

The 50mm webbing width is standard for light-to-medium hand winch straps, distributing load across the drum without excessive bunching. Dacromet coating thickness typically ranges 6 to 12 micrometres and is standard for fasteners and hardware in coastal applications; buyers should confirm the specific coating thickness and salt-spray test duration (ASTM B117 or ISO 9227) against their environment. The 8 metre strap length permits vertical lifts of roughly 4 to 5 metres before the drum is half-spooled, depending on drum diameter. The 5:1 gear ratio implies approximately 140kg of hand pull at the rated load, a figure that assumes ideal lubrication and new bearings. Worm gear or spur gear construction is not specified in the source data; purchasers should ask whether the 1:1 ratio is a free-wheeling position or a direct drive.

Typical applications include trailer loading, fence tensioning, boat haulage, and temporary material hoisting on sites without power access. The 700kg capacity sits within the light-duty range of hand winches, which span from 250kg to 2,500kg for portable units. Buyers in Europe should verify compliance with EN 14492-2 for winches or Machinery Directive 2006/42/EC, as Chinese domestic standards (GB/T) may not align with EU conformity requirements. The supplier lists FOB and CIF as available Incoterms, though port of loading and transit times are not stated. Minimum order quantities are described as flexible, but exact figures are absent from the source. Importers should request a factory test certificate and third-party load-test report before confirming an order, because the consequences of strap or gear failure at full load include serious injury or cargo damage.

Ningbo S&D Metal Work Co.,Ltd is located at No.691-1, Tiantong, Dongwu, Ningbo, Zhejiang Province, China, with 315000 postal code. The supplier holds an imported tier classification and a harbor trust tier on the platform. The response rate is recorded at 0.00 percent, with an average response time of zero hours, indicating that direct communication through the platform has not yet been established or the supplier has not engaged with inbound enquiries via this channel. Buyers should treat this as a signal to pursue direct contact through the listed address or alternative methods rather than expecting rapid platform messaging.

The company profile does not state year of establishment, number of employees, factory floor area, annual revenue, named clients, or specific quality management certifications such as ISO 9001. The source description mentions certifications in general terms without naming standards or issuing bodies. Importers should therefore verify the supplier's manufacturing scope, whether production is in-house or outsourced, and whether they hold a valid export licence. The product focus appears to be metalwork and rigging equipment, though the exact catalogue breadth is not documented. Given the lack of response data, a video factory tour or third-party audit report would be prudent due-diligence steps before committing to a first order.
