Description
RD-D rail scales consist of a load device installed on load cells and a converter.
Load device of the scales has modular construction, which is built in the rail track. Load device has one or several weight measuring platforms, drive on and spacer modules depending on the scales model. A converter transfers measurement results to PC. A PC with a special software is used for information about weighed rail cars processing and displaying.
RD-D rail scales are produced according to OILM R76 and OILM R106 International Regulations.
