JTGC Railway Track Gauge Ruler (600mm / 900mm / 1435mm)

The JTGC Railway Track Gauge Ruler is an essential, high-precision inspection instrument designed for measuring track gauge, super-elevation (cant), and rail alignment. Built with an insulated aluminum alloy frame, it is specifically crafted for harsh trackside conditions across standard railways, urban transit systems, and underground mining tracks.

Key Features

• 1435mm Universal Gauge with Dial / Compass Level: The standard 1435mm gauge model features an integrated carrying handle and a precision top-mounted dial/compass for fast super-elevation (cant) readings from -150 mm to +150 mm.
• Dedicated 600mm & 900mm Narrow Gauges: Specialized narrow track gauges engineered specifically for coal mines, mineral extraction, quarries, and tunneling rail systems.
• 1.0 mm Precision Graduation: Clear, high-contrast laser-etched scale graduations deliver reliable 1.0 mm measurement resolution across all models.
• Insulated Structural Design: Non-conductive insulation protects against accidental track circuit shunting, ensuring safe operation on electrified lines and automated signaling tracks.
• Lightweight & Robust Aluminum Body: High-strength aluminum alloy main bar resists bending and environmental corrosion while remaining easy to carry during long track patrols.
