Cardinal Scale’s SWIM slow-speed in-motion vehicle scale offers the ideal combination of accuracy, space, speed, and economical price point for weighing fully-loaded semi tractor trailers. Weigh-in-motion vehicle scales offer a cost-effective means of measuring truck axle and gross weights without affecting the flow of traffic. SWIM scales occupy only a small fraction of the space needed for a full-length static truck scale and they are ideal for ports, freight terminals, and commercial fleet axle weight monitoring compliance. The SWIM in-motion scale uses a single 12 ft by 30 inch weighbridge constructed of ½-inch thick steel and is supported by four Cardinal stainless steel analog compression load cells.
