Cardinal SWIM Slow-Speed In-Motion Scales

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 SCA stainless steel compression load cells.



  • Weighbridge Size: A single 12 ft X 2.5 ft (3.7m X 0.8m) weighbridge constructed of ½-inch thick steel
  • Load Cells: Utilizes 4 Cardinal 50,000-lb capacity SCA series stainless steel compression load cells
  • Indicator: Cardinal Scale’s 825 indicator programmed with WIM software to weigh each axle of the vehicle as it travels across the scale, plus calculate gross weight
  • Lower Frame: Weighbridge is mounted inside a single-welded framework. This lower frame is 13’-9” by 3’-1” (4.2m X 1m) and is 15” (0.4m) deep
  • Includes: SWIM standard set-up includes SWIM scale with loop detector coil, pole-mountable trim box, universal-mounted 825 weight indicator with WIM software, and a P600 ticket printer
  • Options: SWIM can be interfaced with printers, traffic signal controls, alarms, over-height detectors, and remote weight displays
  • Speeds: The SWIM scale will provide gross vehicle weights at speeds up to 20 mph (Note: As speeds go up, accuracy will go down. 7-10 mph should be the target speed)
  • Accuracy: Provides gross vehicle weights within 1% at speeds less than 10 mph
  • Static Weights: SWIM can also be used as a static scale to weigh single axles for an even more accurate measurement (Note: When used statically the SWIM meets NIST Class III tolerances).
  • Nominal Capacity: 60,000 lb
  • Paint: Frame and weighbridge are protected by a baked-on epoxide polyester powder coat
  • Warranty: Covered under Cardinal’s standard one-year warranty against defects in materials or workmanship
  • Applications: Freight terminals, mining/rock quarries, ports (SOLAS regulations), agricultural, sorting and pre-screening, and commercial fleet axle weight/gross weight checking
  • Shipping: 14 ft X 3 ft X 1.5 ft – 6500 lb (if all parts are packaged inside the lower frame and the weighbridge is inside on blocks)


  • 1/2-inch Thick Steel Deck with Access Covers
  • 12 ft x 30 in Welded Steel Weighbridge
  • Can Also Be Used for Static Weights
  • Includes Loop Detector Coil – Printer – 825 Indicator with WIM Software
  • Provides Gross Vehicle Weights Within 1% at Speeds Less Than 10 mph
  • Saves Time and Avoids Traffic Congestion
  • Small Footprint – Requires Minimal Space
  • Uses Four Stainless Steel SCA Compression Load Cells
  • Weigh Axle Weights Plus Total Weight up to 20 mph
