FRONT FORK / REAR LOADER / ROLL-OFF / TRANSFER TRUCK SYSTEMS
Front Fork System – R506
S.I. On-board, through its sister brand Vulcan Scales offers a Front Fork Scale designed for front loaders in refuse applications. The rugged, bolt-on weight sensing forks replace the trucks existing forks or can be purchased with a scale ready cross tube assembly. Machined from a solid bar of high strength alloy steel and plated for corrosion protection, the light weight fork scales have a negligible impact on the trucks weight.
R506 - Manual Front Fork Scale System (3.5”,4” and 4.5” cross-tubes)
R516 - Weigh-In-Motion/Static Front Fork (3.5”,4” and 4.5” cross- tubes)

Fixed Six Point Scale System - 9101050
The S.I. On-Board Body Scale system uses 13” side connector shear beam load cells for both tipping (bodies that tip to dump and tip for service) and fixed (bodies that are fix mounted and do not tip for service) refuse applications. Typically four to six load cells are used depending on your specific application.

9150 - Meter Load Cell Based Systems
Deflection Transducer Scale System
The S.I. On-Board Deflection Transducer Scale System uses either the standard deflection transducer, the neutral axis deflection transducer or both. The deflection transducer combination is based on the suspension used in the specific vehicle being scaled. The deflection transducer scale system is a lower cost alternative for those applications needing to maximize the vehicle load without the higher accuracy of load cells. A variety of kits are available for different configurations, suspensions, or axle group weights.

On-Board Roll-Off Scale System
The S.I. On-Board Roll-Off Scale for the 2 ½” and 3” rear hinge pin designs use proven technology to give you the reliability and accuracy you expect. The VSL Hydraulic Sensor combines our transmitter and sensor into a single stainless steel housing and obtains weight be measuring hoist cylinder pressure. The shear pin load cells replace the existing shear pins and measure weight in the rear assembly. For low hinge configurations a 26” shear beam is used. Optional retaining collars allow adapting to different roll-off configurations. Easy to operate electronics provide total weight of the container or axle weights to the driver in the cab.

TUFFER Front Loader Scale Solutions for the Refuse Industry
TUFFER Weigh In Motion Loader Scales will provide the information needed to load maximum weights faster, and keep trucks moving without going to a central scale location. This means you get increased productivity on every load, every day. On-Board scales make it faster to load accurate weights every time and Tuffer is designed to do the job and survive the rugged environments found in refuse environments.
We rely on our SI On-Board Scales every trip to ensure that we maximize our loads.
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.
