Fully Automatic SBT ROL Machine
Rate-of-loading controlled static bend testing for moment of resistance (MR) and moment of failure (MF) — eliminating manual pump inconsistencies and meeting IRS loading-rate requirements.
Algorithmic Rate-of-Loading Control
Manual hydraulic pumps struggle to hold the mandatory 30–40 kN/min loading rate, causing shock loads, inaccurate strength readings, and non-compliance. This machine uses proprietary algorithms to lock into the required loading rate with a strictly linear load increase — automatically holding peak loads for the mandatory 3-minute visual crack inspection.

Dual-Standard Compliance
One machine handles both main-line and turnout sleeper geometries — calibrated for IRS-T-39 and IRS-T-45 with real-time load graphing and SCADA integration.
Precise Loading
Algorithmic feedback loop maintains ±1 kN/min rate control — meeting the exact 30–40 kN/min window required by Indian Railway standards.
Inspection Ready
Digital load curves, peak hold records, and pass/fail logging feed directly into the unified SCADA platform for RDSO inspection documentation.
Universal Design
Handles both T-39 main line and T-45 turnout sleeper geometries on a single machine — no separate equipment for different sleeper types.
