Import 50m Magnetic Versine Measuring Kits — Buy in wholesale FOB from Supplier in China

The 50m Magnetic Versine Measuring Kit from Wuhan Linkage Track Equipment is a precision instrument for railway curve measurement, also known in the industry as a string box. The model ZSH-50 offers a 50 metre measuring range in a compact ABS plastic housing measuring 133 mm by 66 mm by 26 mm. The unit weighs 210 kg according to the source data, though this figure may reflect a bulk or packaged weight rather than the handheld unit itself, and buyers should clarify the net product weight directly with the supplier.

The kit employs magnetic attachment to rail heads for stable positioning during versine measurement, a standard method for determining track curvature track alignment and curvature in maintenance protocols. The ABS body is specified as yellow and designed for field portability, pocket storage, and resistance to impact and weathering typical of railway environments. Standard railway versine measurement requires string tension consistency and graduated scale readability under variable lighting, functions this kit is engineered to perform.

Railway maintenance contractors, track engineering firms, and infrastructure departments in national rail networks use such kits for routine curve positive vector surveys. The ZSH-50 suits medium-range alignment checks on mainline, yard, and industrial spur tracks where 50 m chord lengths provide adequate resolution. Buyers should confirm whether the kit includes replacement strings, calibration certificates, and magnetic adapters for different rail profiles, as these accessories vary by configuration.

Wuhan Linkage Track Equipment Co., Ltd. operates from Room 1007, Block B, Building 1, Huagong Science Park Modern Service Industry Base, University Park Road, East Lake High-Tech Development Zone, Wuhan City, Hubei Province, postal code 430000. The company holds a harbor trust tier on the platform, indicating a verified business registration with basic documentation submitted, though this represents an entry-level verification rather than advanced audit status. The response rate shows 0.00 percent with zero average response hours recorded, which suggests either a new listing, dormant account, or data tracking issue that potential buyers should note when evaluating communication reliability.

The supplier specialises in railway track equipment, with this versine measuring kit representing their offering in track geometry instrumentation. No information is provided about manufacturing certifications, ISO registration, export experience, or client references, so buyers should request these directly. The product description emphasises portability and ease of operation, positioning the kit toward maintenance crews requiring field-deployable tools. Given the incomplete response metrics, importers should plan for potential delays in quotation and technical clarification, and consider initiating contact well ahead of procurement deadlines.
