Cardinal’s CWL-40 axle load scales are constructed of heavy-duty cast aluminum for high strength-to-weight ratio. Weighing only 57 pounds (26 kg) per 28.5 x 17.5-inch (72 x 45 cm) platform and featuring integral carrying handles, the CWL-40 axle pads are light enough for easy transport from location to location. The interlocking rubber ramps easily snap in place once you’re ready to weigh. The CWL-40KIT contains two CWL-40 axle pads with 20-ton capacity, rubber ramps, and necessary cables, plus Cardinal’s 190A weight indicator with axle weighing software and P150 thermal ticket printer. Both the 190A indicator and P150 printer may be powered by rechargeable lithium ion batteries (optional – 190A / standard – P150). The 190A indicator features two RS232 serial ports (to connect with a printer and remote display) and the one-inch-high backlit LCD is visible in direct sunlight and at night.
