Cardinal Pit-Mounted Truck Scales Provide Port of Miami Ability to Weigh Greater Volume of Freight

Posted on by

Two Additional Cardinal Scale Pit-Mounted EPR Truck Scales Provide Terminal the Ability to Weigh Greater Volumes of Freight. Major ocean transport company adds more Cardinal EPR truck scales and 210 indicators to expedite traffic flow for 600 truck weighments per day at busy Port of Miami.

Traffic congestion was becoming a major issue at the Port of Miami with a steady increase in export freight volumes over the last several years and the completion of a new underground truck tunnel leading into the port. A lengthy line of trucks were typically waiting to be weighed before entering the freight terminals at the port.

It became apparent that a solution was needed to be able to move this increased traffic through the port more quickly and efficiently.

 

Cardinal Scale Pit Type Truck Scale

One of the largest ocean transport companies at the Port of Miami rearranged their container yard and came to Cardinal Scale seeking a solution for its truck scale needs.

Cardinal Scale had several meetings with Port of Miami officials and the ocean transport company’s personnel during which various yard and scale layouts were considered, including above or below ground scales, steel or concrete decks, network connectivity, and weight documentation.

It was ultimately decided that there would be two new inbound steel deck truck scales installed below grade in deep pits. The deep pit request presented an important challenge: How to ensure that a 4 1/2 foot deep pit would remain dry at just above sea level on an island?

Cardinal Scale had stressed the importance of keeping the pit dry during the design process.

Therefore, the ocean transport company contracted with an engineering company that designed and built an elaborate self-contained underground pump station, which was built adjacent to both scale pits to prevent the pits from flooding.

The ocean transport company decided to purchase two new 13570-EPR truck scales from Cardinal Scale, which were slightly modified to be installed in the pits. The pit design was chosen to save yard space, as well as, producing an easier and safer method for drivers and other personnel to move in and around the trucks. A steel deck was chosen over a concrete deck to avoid delays associated with the curing time of a concrete deck.

The scales were connected to Cardinal Scale model 210 weight indicators fitted with 10/100 Ethernet cards and attached to P500 receipt printers, which were installed in two separate scale houses. The Ethernet cards allow them to communicate the weight data to their remote server and the ticket printers allow them to produce a hard copy for the truck drivers, which not only includes their truck ID, but the time and date of weighment as well.

The ocean transport company’s freight terminal at the Port of Miami operates 24/7, 365 days a year.

It can now weigh more than 600 trucks per day with the addition of the two pit-mounted Cardinal truck scales. The ocean transport company has substantially reduced the weigh-in time for each truck, which in turn allows them to load the freight containers on the cargo ships more efficiently.

The additional truck weighing scales have led to shorter lines of trucks, thus improving the overall traffic congestion at the Port of Miami as well.

What Type Of Scale Should A Metal Recycler Buy?

Posted on by

Another popular question we are asked is: How many types of 70 foot truck scales exist (low-profile, pit style, full electronic, concrete deck, steel deck)? Is there one particular type you would recommend over another for use within the recycling business? What benefit does it present to pick one over the other?

Truck scales come in numerous sizes and types. Truck scales could be portable axle, weigh-in-motion, self-contained transportable, electro-mechanical, electronic, and hydraulic versions. In a traditional truck scale you would need to choose either an above ground or pit style scale. Then, a painted steel deck or concrete deck that you would pour on location.

For the recycling business, generally the most effective choice will be the steel deck electronic truck scale because it provides the fastest setting up time and if you’re replacing an existing scale, the lowest down-time in swapping out a pre-existing truck scale. If the metal recycling company is replacing an older truck scale installed inside a pit that is experiencing water damage concerns, a hydraulic truck scale could be a good decision to think about for an advancement. The load cells within a hydraulic truck scale have excellent defense to water and lightning issues.

As with any big decision like this, we recommend that you contact your local scale company to provide you with a recommendation and truck scale price quote. It could be that your best choice might be a pit style scale. Or maybe a hydraulic scale would work best for you.  A local scale dealer should be able to provide that recommendation to you and present you with several buying options to consider.

Summer is almost here, Truck Scale Maintenance Ideas

Posted on by

We’re just about ready to head into the busy summer months. In a lot of cases, it is also a busy time for your truck scales. Spring is the best time to get the following maintenance done, because all the melting snow (in some areas) creating running water, mud and muck can wreak havoc on your truck scale operations; washing debris into pits and foundations, and damaging equipment. Not to mention the critters who have taken up residence over the long winter. We recommend completing the following steps in late spring to ensure you are up and running in time for the busy summer season. Continue reading →

Checking Devices

Posted on by

As we continue to look at service of truck scales, this month we look at checking devices.  Some vehicle scales utilize suspension systems that don’t require checking devices, eliminating a time-consuming step in your service protocol.  If your scale has checking devices, make sure they are working properly. Inspect check rods to make sure the attachment points are solid. Check for binding.

If there is a problem, weight readings will be inconsistent from section to section. Inspect hardware to ensure jam nuts are tight, rods are level and free of foreign material, and washers are not rusted or distorted. Even if they are working properly, replace corroded hardware components so they don’t fail in the future when you least expect. Continue reading →

What is Concentrated Load Capacity and NTEP?

Posted on by

Concentrated Load Capacity, or CLC, is an industry recognized rating of a vehicle or axle load scale. The rating defines the maximum load for which the weighbridge is designed as applied by a group of two axles with a center line spaced 4 feet apart and an axle width 8 feet apart. When a CLC load is applied to the weighbridge during a National Type Evaluation Program test, the NTEP tester records the displayed weight. If the scale falls within accepted testing tolerances, the scale has that CLC weight value recorded as the CLC on the Certificate of Conformance.

The CLC rating is not a measure of weighbridge strength or rigidity, because weighbridge deflection is not measured in the NTEP test. It is irrelevant if the load weighbridge sags 1/10th of an inch, or 10 inches, as long as the scale weighs within the accepted tolerance. The scale’s CLC weight rating passes in either case. A high CLC rating could be given to an extremely flexible deck sitting on load cell mounts which are capable of accurately handling the side loading resulting from a severely sagging weighbridge.

The Rice Lake SURVIVOR truck scale line boasts a 45 ton (90,000 pounds) CLC rating. With most legal highway weight limits being a fraction of Rice Lake’s rating, owners of a SURVIVOR scale can expect a long lifespan through Continue reading →

Steel or Concrete Weighbridge for Truck Scales?

Posted on by

The structural integrity of the truck scale weighbridge is the single most important consideration in the purchase of any truck scale. A failing weighbridge results in continuous problems that can only be solved with replacement. Rice Lake Weighing Systems standard model truck scales are comprised of beams spaced no further than 12 inches from center line or 8 inches from the edge of one flange to the next. This design ensures that a truck tire is on an I-beam at all times and never between.

Concrete Deck
While a concrete deck needs approximately 21 to 28 days to cure, it offers greater resistance to rust and corrosion from road salt and generally requires less maintenance than steel decks, helping to extend the life of the scale. A concrete surface also yields better traction with rain and snow. Because of their design, concrete decks distribute the load over a wider area than steel decks. Rice Lake SURVIVOR® Series concrete deck truck scales are poured at the job site and typically have cure strength of 4,000 PSI at 28 days. The concrete is reinforced with steel rods and a minimum of two wide-flange main beams and seven wide-flange beams below. The Rice Continue reading →

Above Ground or Pit type Truck Scales

Posted on by

Until the early 1970s, all truck scales were mechanical and installed in expensive concrete pits. Today, most heavy vehicle scales are installed above ground or in concrete pits with slab type foundations. With the benefit of new modular construction, scales can also be installed in a shallow pit, as opposed to the deep pit required by older mechanical scales.

One of the biggest reasons for choosing a pit type installation is space or lack of it. A pit installation requires less space than a pitless installation due to the approaches, as sloped approaches to grade are generally required for pitless foundations. However, pit type truck scales require sump pumps and drains, and are more vulnerable to accelerated rust and corrosion due to the potential of standing water in the pit.
