Wayside Rail Lubricator
ProductOverview
A wayside rail lubricator is a trackside dispenser applying grease to the rail head as trains pass over. On heavily-trafficked routes with tight curves, rail wear accelerates due to friction. Applying a thin grease film reduces friction, heat generation, and noise, and extends rail life.
How it works
The Wheel Detection Sensor is installed at the trackside, positioned to detect approaching wheels. As the leading wheel passes, the Sensor Element (inductive proximity sensor or mechanical contact) sends a pulse signal to the control board.
The Pump Drive Motor turns the Gear Pump, which draws grease from the reservoir and pressurises it at 1–5 bar. The pressurised grease flows through control valves into the nozzles, which spray a fine stream onto the rail head.
The pump runs for a precise duration (typically 0.5–2 seconds), dispensing 100–500 g of grease per trigger event.
