Tensioning devices are commonly made from high-strength steel, zinc-plated steel, or stainless steel. The material grade for carbon steel is Q235B per GB/T 700, and zinc plating (Zn-8) per ISO 2081 is applied for corrosion resistance. The choice of material depends on the application and environmental conditions.
Selection should be based on tire size, chain type, and operating conditions. Key parameters to consider include tension range (50–200 mm), maximum tension force (5–20 kN), adjustment accuracy (±1 mm), and operating temperature (-40°C to 85°C). Always verify model-specific values with the legal manufacturer or supplier.
Regular inspection of the locking mechanism and tension settings is recommended. Check for signs of wear, corrosion, or damage. Ensure that the device is clean and lubricated as per manufacturer guidelines. If the device fails to maintain tension or shows excessive wear, it should be replaced.
Common failure modes include thread stripping, locking mechanism failure, and material fatigue. Over-tensioning can cause deformation or breakage, while under-tensioning leads to chain slippage. The breaking load is 30–80 kN, providing a safety factor of 4–5 over maximum tension. If any component shows signs of cracking or permanent deformation, the device must be replaced.
