Light-based communication system improves safety and efficiency at the dock

Every autumn, one of the world’s largest receiving stations for fruit in Tomah, Wisc., is responsible for processing more than 40% of Ocean Spray’s annual Wisconsin harvest. During peak harvest, as much as 150 to 180 loads of fruit may be cleaned, processed and shipped per day. By installing a system of vehicle restraints and color-coded dock lights, the company has significantly improved safety and efficiency at the dock.

“Prior to the new system, you never knew when a trailer was at the dock,” says Leroy Kummer, receiving station manager at Ocean Spray. “There are a lot of safety issues that can occur when things are moving at such an increased pace to meet the demands of the harvest season. The new system enables drivers to see when it is safe to enter and exit a trailer, avoiding unnecessary mistakes and injuries.”

The integrated vehicle restraints and dock lights (Rite-Hite) prevent trailer separation accidents and increase communication at the loading dock. Lights were installed at the upper corners of the dock door to confirm the presence of a truck and the status of the vehicle restraint. These lights let lift truck operators and managers know when it is safe to enter a trailer. Lights were also installed on the dock leveler to confirm the restraint status as an operator exits the trailer.

In addition to increased safety, the facility has noted that the system also saves on staffing and resource costs. “The added efficiency aspect is great,” Kummer says. “Because we have one communication system, we have reduced the need for dock workers to be running in and out checking on wheels or trailer status to unlock full trailers.”
