Advanced Hy-24 Anti-Slip Coefficient Testing Machine

Description 1. Core Function (per GB/T 50205-2020) Slip Coefficient Test for high-strength bolt assemblies (M16 M30) Combined with universal tensile machine, measures anti-slip coefficient (μ) of friction-grip joints in steel structures (bridges, wind towers, high-rise). Test Principle:μ=TF⋅dm\mu = \frac{T}{F \cdot d_m}μ=F⋅dm​T​(T = clamping torque, F = axial preload, d_m = effective diameter) Standards Supported: GB/T 50205-2020 ISO 16047 EN 1090-2 ASTM F959 / A325 / A490 Parameter Specification Measurement Range 10 – 400 kN Resolution ±0.1 kN Indication Error ±1.0% (FS) Accuracy Grade 0.5 (load cell) / 1.0 (system) Channels 4 physical × 24 logical (6 groups) Display 7″ LCD touchscreen Control Mode Auto / Manual Data Output USB (Excel, PDF reports) Power AC 220V ±10%, 50/60Hz Net Weight ~12 kg Package 50×40×20 cm, 15 kg (non-fumigated case) 3. Standard Configuration Bolt Size Sensor Capacity Qty M16 120 kN 4 M20 180 kN 4 M22 220 kN 4 M24 260 kN 4 M27 330 kN 4 M30 400 kN 4 Each sensor pre-calibrated with serial number & certificate 4. Key Features Feature Description Multi-Channel Sync 4 bolts tested simultaneously Auto Calibration One-click zero & span Peak Hold Captures max preload during slip Data Backup Parameter restore via USB Software Windows-based: real-time curve, μ calculation, scatter plot Language English / Chinese (customizable) 5. Test Workflow (Typical) Mount slip plates bolt assembly in tensile machine Connect HY-24 sensor between nut and washer Apply torque → sensor records axial force (F) Record slip load when plates slide System auto-calculates: μ=Ns⋅P2⋅F\mu = \frac{N_s \cdot P}{2 \cdot F}μ=2⋅FNs​⋅P​(N_s = slip factor, P = proof load) 6. Applications Industry Use Case Steel Bridges Friction-type HSFG joints Wind Turbine Towers M30 bolt slip verification High-Rise Buildings Preloaded bolt quality control Railway Fasteners Turnout & track bolt testing 7.
