For Your Investment
Cardinal's Guardian Hydraulic Truck Scales are ideal for the solid waste, aggregate, chemical, grain, and construction industries because they offer a high level of protection against many of the conditions that can adversely affect truck scale installations. Water, lightning, power surges, explosive areas, corrosion, welding, shock loading, extreme temperature fluctuations and even rodents can cause scale problems, all at a cost to the owner. Cardinal's Guardian Hydraulic Truck Scale provides a superior level of performance which protects the scale against these conditions.

EPR Low-Profile Pitless Scale
Over 70 years of scale design expertise are incorporated into these scales. The interlocking yoke and pin design means fast, "No-Bolt" assembly. The EPR allows easy access to load cells and wiring makes installation and maintenance a snap. Installation is not only fast and easy, but also inexpensive. Select from a wide variety of popular capacities and platform sizes available (listed on back) in both Cardinal's checkered steel deck or the pour-in-place concrete deck models.
EPR-LF Portable Low-Profile Scale
This self-contained portable ground hugger scale is the answer for a weighing system that can be moved efficiently from site to site. Great for quarries, sand and gravel companies, logging companies or any other application that must relocate equipment from time to time. The EPR-LF is contained in modules with lifting eyes for easy moving, and features a 5/16" checkered steel deck.
Weigh-In-Motion Screening Scales
Cardinal offers both quartz and load cell sensor based WIM scales and systems suitable for use in a wide variety of applications. Applications ranging from highway weigh stations and ports of entry for enforcement purposes to mainline applications for data collection/traffic flow studies, or for streamlined CVO. The system also includes a comprehensive and flexible software package capable of providing virtually any output format you desire.
CWL - 40 Portable Axle Weigher
Cardinal's model CWL-40 portable axle weighers are rugged, but light enough for easy transport, weighing in at only 60 pounds per platform. They feature rechargeable battery power and can factor axle weight and gross weight. With Cardinal's model P150 battery-operated portable tape printer, you may print axle weight, gross weight, time, and date. The interlocking rubber ramps snap perfectly into place with the CWL-40's unique design.
PRC Low-Profile Pitless Scale
The Cardinal PRC Series is a low-profile, full electronic truck scale. The high capacity PRC's rigid design prevents excessive movement, ensuring long lasting reliabiltiy and accuracy in high traffic installations. The PRC is available in concrete or steel decks, and a variety of capacities.
SRC Concrete Pit Scale
Simple pit installation permitted through the use of Cardinal load cells makes the Cardinal Electronic Pit Type Motor Truck Scale a very practical method of weighing any vehicle. The weighbridge is supported by heavy capacity load cells for quick and accurate weighing of the truck and its cargo.
760PS/PA Portable Electronic Axle Scale
Cardinal's completely portable, two-module axle load scale gives you the performance you need, where you need it and when you need it. A real lightweight (only 400 lbs per aluminum platform) that handles the heavyweights (60,000 lbs capacity). Each scale comes complete with either steel or aluminum ramps, NEMA 4 junction box, environmentally-protected stainless steel load cells, and four access ramps.
PRL/PSRL Mechanical, Self-Contained
Cardinal's PRL Series heavy duty, self-contained mechanical truck scales are made for endurance and accuracy. Tandem units are simply composed of two or more scales of the same or different platform lengths tandem-connected for greater capacity. When split, each unit is a self-contained scale in itself, offering 3-in-1 scale flexibility. The 5/16" full checkered steel deck plate is standard and an optional wood deck is also available (PSRL models).
Unattended Weighing Operations
Cardinal Scale's unattended systems provide an effective solution for unmanned vehicle weight management that is fast, accurate and easy to operate. Featuring the model 777 or 788 programmable indicators with truck storage software in a weatherproof outdoor enclosure, the system is available with barcode badge reader or proximity badge reader, and/or ticket printer.
SRL/ASRL Electro-Mechanical Pit and Axle Load
Cardinal's SRL electro-mechanical pit type truck scale and ASRL axle load scale are designed for fixed installation in a concrete pit. Since its introduction, Cardinal has continued to modernize and improve its design: only four main levers with one transverse lever on the four section scale and two main levers withone transverse lever on the two section scale.
Cardinal's "ican" Intelligent Junction Box
Cardinal's iCan system provides a digitally-controlled, high-performance weighing and diagnostic environment for your scale where every step from installation to operation to maintenance is not only simplified, but closely monitored by the latest ISP flash micro-controller-based circuitry and reported using advanced internationally standardized CAN serial bus. What this means is the cost of ownership for your scale just got smaller since system faults are automatically detected and reported, resulting in less downtime and fewer service calls.

The iCan diagnostic display provides a scale-side weight indicator where the scale technician is working thus saving them time going back and forth to the indicator which saves you service call money. The on-board display provides a 6-digit display of load cell millivolt output, weight, and total scale weight while a single character identifies the load cell source. The iCan system controller module is housed in a IP66/NEMA 4X junction box and is connected to the 788 indicator with transient-free plastic fiber optic cable, twisted-pair copper wire, or optional glass fiber optic cable.

The 788 indicator provides on-screen viewing of individual load cell report data, ensuring quick and concise information on your scale's performance. Cardinal's patented SmartCal® feature allows quick single-pass calibration without the need for manual adjustments. iCan's diagnostic software automatically identifies and reports potential problems before they can interrupt your weighing operations.

Cardinal's iSite software and hardware facilitates electronic communications from dealer or support locations to iCan scale sites. The communications can be performed via network TCP/IP connections, direct serial port connections, or dial-up modem connections.

Status reports may be electronically requested from each iCan site at any time. These reports include weight information and millivolt readings for each load cell of each scale. An automatic request feature may be used to obtain new status reports from a site automatically at a specified interval.

iSite software automatically updates a summary report for each site as individual reports are requested. The summary report for a site provides quick comparison of load cell readings over the history of the site, and may be opened with Excel® to allow further analysis or graphing of the data.

Off-road scales have been Cardinal's specialty for 50 years

Although Cardinal has a broad line of standard scale models, we also manufacture custom truck scales of different lengths, widths, and capacities for your special needs. The mining, construction, steel, aggregate, and forestry industries demand rugged scales built to unique specifications that will provide dependable performance for extreme duty cycles. For example, Cardinal designed, manufactured, and installed the world's largest truck scale pictured above at the La Plata Mines in New Mexico (500 tons in capacity, 25 feet wide by 125 feet long with a mechanical beam and digital weight indicator). It's no wonder that Cardinal is well-known for building extra heavy-duty scales to accomodate the largest off-road vehicles.
