Application The AMSTEL Torpedo Weighing Rail Scale is a pit less state of the art static weighing scale for hot torpedo cars. High – precision , high–temperature load cells are installed between the existing rail clamps and the existing wooden or concrete sleepers. They reliably transmit all vertical forces applied by the torpedo car wheels , with a high degree of accuracy and repeatability. The weighing system is installed without a foundation and can be installed without additional effort during a normal track maintenance period.
