National Carrier to Install SI Technologies Lift Truck Scales at 15 Freight Terminals

TUSTIN, Calif., April 1 -- SI Technologies, Inc. , which designs, manufactures and markets high-performance industrial sensors, weighing and factory automation equipment and systems, today announced that it has received a contract from a national less-than-truckload (LTL) freight transportation company for its Allegany(R) lift truck scales. The equipment will be installed at 15 freight terminals located throughout the continental United States and will be delivered to the customer in the fiscal quarter ending April 30, 2003.

Lift truck scales are the accepted standard throughout the LTL industry and are used to verify the weights claimed by shippers. Lift truck scales also allow dock workers to accurately weigh freight without a reduction in cross-dock productivity. "A typical freight carrier will realize a payback on its investment in our lift truck scales within a month after installation through the correction of inaccurately stated shipper weights," commented Rick Beets, President and Chief Executive Officer of SI Technologies, Inc. "We are pleased that this national trucking company selected our Allegany(R) equipment after eight months of extensive testing in competition with equipment available from two other major lift truck scale manufacturers."

The Allegany(R) lift truck scale is certified "legal-for-trade" by all 50 states and provides weights accurate to within 0.01% of the applied load, even when weight is distributed in an out-of-level condition.
