iDock® Alert Light Communication System

Loading Dock Communication and Controls

The iDock Alert Light Communication System is an enhanced version of McGuire’s simple Dock Alert and provides a reliable warning system that establishes a clear line of communication between truck drivers and dock personnel, thereby reducing the risk of accidents at the loading dock.  

As a truck approaches the dock, exterior lights will flash green while interior lights are red.  Once the truck is in position, the dock attendant will open the overhead door, secure the trailer with an optional restraint, and raise the leveler onto the trailer.  This action will trigger one of the installed sensors to automatically change the exterior light to red, letting the driver know not to pull away, and interior light to green, indicating that it’s safe to proceed with loading/unloading.

High Visibility Signs Are a Standard Part of the iDock Alert

A set of standard read and mirrored image read signs that read “Caution. Pull in or out on Green Only” are provided as an added measure of safety with the Dock Alert communication system.

Exterior Light System Is Designed for Maximum Durability and Visibility

Exterior polypropylene housing will not rust, pit or corrode. The shallow depth of the unit helps to protect from incoming trailers. A yellow housing is highly visible and the usage of integral eyebrow-type sun visors over the red/green lights creates extended visibility.

A means to Safely Communicate Trailer Positioning That Is Cost Effective Yet Dependable

Usage of inside and outside red and green lights that are always in an opposing mode can inform your truck drivers and dock attendants the status of loading and unloading. They come complete with safety signs.

Two Means to Activate the Dock Alert Provides You With a Maximum Flexibility in Design

Manual Operated activation, automatic activation with interconnection to dock leveler or overhead door.

Interactive Message Display

With the iDock Controls Message Display, operators can view equipment and system information, maintenance history, counters, and more.

Availability of Sensors

These optional sensors allow you to monitor forklift traffic as well as truck position at your loading dock.
