Refuse Front Fork System image

Front Fork System – R506

SI On-Board (through our sister brand, Vulcan Scales) offers Front Fork Scales designed for front loaders in refuse applications. These bolted on, rugged weight sensing forks replace the trucks existing forks, or available for purchase with a scale-ready, cross-tube assembly. Made from solid bars of the strongest alloy steel and reinforced with plates for corrosion protection, SI lightweight Fork Scales provide superior strength with virtually no impact on the truck’s weight!

Fixed Six Point Scale System - 9101050

SI Body Scale system uses 13” side connector Shear-Beam load cells for the refuse applications of both tipping (bodies that both tip to dump and for service) and fixed (bodies that are fix mounted and don’t tip for service). Typically, four to six load cells are used, but we also align our systems to meet any of your specific operational needs. Get On-Board today.

Refuse deflection transducer system

Deflection Transducer Scale System

Depending on the application, SI Deflection Transducer Scale systems use either standard (neutral axis) or multiple deflections. The deflection transducer combination is determined by the suspension used and the specific vehicle being scaled. Our Deflection Transducer systems are efficient, lower-cost alternatives for vehicle applications needing to maximize loads without the higher level of accuracy provided by load cells. A variety of kits are available for different configurations, suspensions, and axle group weights. Get On-Board today!

On-Board Roll-Off Scale System

The SI Roll-Off scale for the 2 ½” and 3” Rear Hinge Pin designs combines years of In-Field experience and technology to provide the reliability and accuracy beyond expectation. The VSL Hydraulic Sensor unites our transmitters and sensors into single stainless steel housing to obtain and measure hoist cylinder pressure.

SI Shear Pin load cells replace the existing pins to measure weight in the rear hinge assembly. Optional retaining collars allow adaptation to different roll-off configurations. Get On-Board with Easy-to-Operate electronics that communicate the total container or axle weight to the driver.

We rely on our SI On-Board Scales every trip to ensure that we maximize our loads.

Jake ThompsonTTT Timber, Inc.

We use SI On-Board Scales on our fleet of log trucks. Whether our trucks are running off road in harsh conditions or over the highway, the SI scales consistently provide accurate readings. We rely on our SI scales every trip to ensure that we maximize our loads. The majority of our haul routes pay by the ton so it is critical for us to maximize our revenue. Our SI On-Board Scales are very accurate, and our confidence in them has been proven through years of use. We have been pleased with how easy the scales are to use and adjust, and with their longevity in rugged conditions.
