SI Onboard is an industry leader in the manufacturing of on-board weighing systems for forestry,
waste management, aircraft and aggregate markets.
SI (Structural Instrumentation) was formed in the late 1960’s, and pioneered the on-board scale industry while simultaneously shaping the
on-board weighing market. Later on, SI acquired four more companies: Lodec, Evergreen Weigh, Allegany and Revere. These acquisitions
expanded the SI product line (aircraft scales, bucket loader scales and lift truck scales) and positioned SI as a top load cell producer having
Revere’s leading technology. Dominant in the U.S. and Canada early on, SI Onboard quickly expanded to relevance in Central and South
America, and has far-reaching brand recognition in Asia. Synonymous with quality, reliability, and service, SI Onboard stands firm as a
recognized market leader. We continue to innovate and develop new products to satisfy the ever-evolving needs of our valued customers
SI Onboard has established an extensive dealer network throughout the world that sells and services its products. In North America, we
have sales and service branches in Norwood, MA, City of Industry, CA and Kelowna, Canada.
