Welding and Track Maintenance Equipment

Light Profile Grinder RPLE

The Light Profile Grinder RPLE is part of Pandrol’s range of grinding equipment that is designed to maximise the life of the track across all rail heads and profiles.

The Light Profile Grinder is a precision grinder used to complete the final stages of profile grinding on the rail head after aluminothermic or flash-butt welding. It has been specifically designed to allow very accurate adjustments, so that the whole rail head top can be perfectly restored in a single operation. Two vertical rollers, seated on the rails can be used to ensure a perfect rail profile copy in every position.

When it is not in use, a quick collapsible supported seated on one sleeper maintains the grinder steadily on the rail.

Technical Features

  • The Light Profile Grinder has a star grinding wheel with a central sunk nut. This allows accurate adjustment of the grinding stone in 0.08 mm increments
  • The grinding wheel rotates at a speed of 6,500 rpm
  • Vibrates at 9 m/s2 with an acoustic pressure noise level of 93 dB (A) and an acoustic power noise level of 106 dB (A)
  • There is a wide distance of 1300 mm between the rail guiding rollers
  • For safety, an emergency stop is located on the machine

Advantages

  • The distance between the guiding rollers helps the operator to quickly achieving grinding tolerances, resulting in a significant reduction in working time
  • The extremely accurate, easy grinding wheel adjustment makes human error much less likely
  • The grinding of the whole rail profile can take place in one operation, saving time and money
  • The machine’s light weight and compact size make it easy to move and use
  • The Light Profile Grinder RPLE is environmentally friendly, because the electric engine can be connected to the electrical grid, preventing carbon emissions
