LRGM 2-12

The LRGM 2-12 is a turnout grinding machine for the machining of the rail head. The machine composes two coupled grinding units LRGM 1-6, each with 6 grinding spindles with independent angular adjustment. They are driven by 15 kW frequency controlled electrical motors. The grinding process is monitored automatically. The machine can be equipped with an integrated laser measurement system for the analysis of the transverse and longitudinal rail head profile.

The composite grinding machine is driven by a coupled generator so that no cables has to be installed along the working site. The grinder can be easily railed in and out with a ramp of a rail vehicle or by crane.

The LRGM 2-12 turnout grinder can be used for removing of the rolling skin, the elimination of rail corrugations (grooves) and short waves on the rail head as well as for the re-profiling of the rail head. The grinder is efficient for grinding of turnouts, machining of railroad crossings, grinding of welding, machining of taper rail and for winning the transverse and longitudinal target profiles in short rail sections.
