FIELD: transport.
SUBSTANCE: invention relates to railway transport and can be used for measuring coefficient of friction between wheel and rail. Proposed complex comprises truck, roller tribometry instrument and data recording and processing hardware. Said portable tribometry instrument is furnished with strain-gage transducers. Said data recording and processing hardware comprises PC, strain amplifier connected with PC and strain-gage transducers of roller tribometry instrument. Said truck has independent power supply and can accommodate roller tribometry instrument and data recording and processing equipment.
EFFECT: simple design, higher mobility.
