Load measuring system RAK series

direct-contactwheelfor railway applications

The RAK system by A.S.T. is used to determine each wheel load on the track for the entire rail vehicle according to DIN27201 standard. Our corresponding in-house software can be used to document and archive the determined data as well as all car-typical information. A.S.T. Wheel Load Measuring System for Rail Vehicles A.S.T. RAK 402 is a highly accurate wheel load measuring system for rail passenger vehicles. It contains 8 weighing modules for measuring 4 axles of rail car as a standard configuration. It also has either single or dual gauges on each weight module, or combines with more weight modules together based on the requirement. RAK 402 system is designed for easy for installation or adjustment, and is user friendly to operate or calibrate. It complies to the German standard DIN 27201-5: “State of railway vehicles - Basic principles and production technology - Part 5: Checking of wheel forces and vertical wheel set forces of railway vehicles”. The weight modules will be installed in concrete pits. Only a fixed installation provides an accuracy and process capability as required in the German standard. The purpose of using wheel load measurement systems is to prevent derailment of railway vehicle, and to assure to lower wear and tear the static vertical load distribution within the two wheels on an axle, which must be rather even. The wheel load measurement has to be carried out after the following tasks. - mounting of car body onto bogie during manufacture; - accidents where a wheel load might be influenced; - working on the springs of the bogie; - change out of the wheel set or the bogie
