The OTR Concrete Deck is well suited for resisting corrosion and rust, and generally requires less maintenance than steel decks, helping to extend the life of the scale. A concrete surface also yields better traction in wet and icy conditions. Because of their design, concrete decks distribute the load over a wider area than steel decks. Concrete decks are poured at the job site and typically have a 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.
Weighbridge Design
Designed and built to federal bridge standards, the full six-inch thick reinforced concrete deck of the OTR encases hundreds of 3/4-inch shear studs welded to the supporting 6-inch I-beams, creating a monolithic 12-inch thick rigid weighbridge. The concrete deck design incorporates galvanized steel sheets working in conjunction with I-beams to ensure that concrete remains above the neutral axis of the weighbridge. Concrete functions best when it remains above the neutral axis in a compression application. Flexing from tension loading can damage any concrete that extends below the neutral axis. The eventual cracks caused by this flexing would lead to deterioration of the deck and eventual scale failure.
Load Cells and Mounting System
Each load cell has an individual capacity of 75,000 pounds, compared to only 50,000 pounds in many competitive models. Higher capacity load cells handle heavier loads with far fewer failures. Wire-braided copper transient bypass cables are provided at each load cell mount for individual load cell protection from direct lightning strikes to the scale or weighbridge. Load cells and electronic components have top access through the scale deck, allowing for convenient maintenance, even where space is limited.
Durable Finish
All SURVIVOR scales are thoroughly cleaned before painting to remove mill scale, oils or other surface contaminants. An asphalt undercoating is applied to the interior and underside of the entire scale. A high-performance epoxy primer is applied to all steel before the specialized hard-coat alkyd enamel completes the process.
Lightning Protection
Every SURVIVOR truck scale comes complete with a surge voltage protection system. The junction box is provided with individual transient circuitry protection. The entire system is grounded to a single-point grounding system connected to the power ground. With the introduction of single point grounding, you will not experience the loss of load cells associated with other competitive designs.
Easy Expansion
Versatile and cost-effective, the OTR was designed to change with your business. Heavy-duty, self-seating hinge connectors offer easy installation of the pre-assembled modules, and simplify future expansion.
