Alliance Scale, Inc. says its new line of low-profile, pit-less, high-capacity, modular railroad track scales are less expensive to build and install than conventional pit-style railway scales. The platforms on the Alliance/Rice Lake Survivor PL Railroad Track Scale modules are available in 12-foot, 6-inch, 15-foot, and 18-foot lengths, are 7 feet, 8 inches wide, and 18.5 inches high for weighing loads up to 170 tons. The scales feature wide flange I-beam construction, heavy weighbridges, and high span deflection ratios.
