Overview
Dok-Lok® Style Light Communication Systems provide light-based communication at the loading dock to increase safety and productivity. The systems indicate when personnel can safely enter or exit a trailer and when truck drivers may depart. Two main approaches are available: a Dok-Lok® style for integration with Dok-Lok® vehicle restraints and advanced interlocks, and a traffic-style stop-and-go toggle for basic signaling requirements.

Key Features

• Enhances communication inside and outside at the loading dock
• Dok-Lok® style supports full integration with future equipment and interlocked sequences of operation
• Traffic-style provides a manual stop/go/neutral toggle for simple installations
• Available for different budgets: immediate full-system or incremental deployment
• Includes inside control/communication box, outside signal lights and interior/exterior instructional signage

Benefits

• Designed and Installed for Productivity – enables future integration of additional safety solutions and interlocked sequences to support operational protocols
• Safety at the Loading Dock – reduces risks such as early trailer departure, forklift run-off-the-dock and pedestrian/forklift collisions by clearly indicating safe/unsafe conditions
• Communication and Control – Dok-Lok® style user interface (NEMA 4X) with membrane switch buttons for broader equipment integration; traffic-style uses a manual three-position toggle
• Connected Capabilities – components can link to digital platforms for real-time alerts, analytics and visibility into equipment and dock performance

System Integration and Options

• Optimizable with Dok-Lok® Vehicle Restraints and other Rite-Vu™ hazard-recognition components
• Enhances line-of-sight products such as Corner-Vu™ and Leveler-Vu™
• Can extend pedestrian safety (Pedestrian-Vu™) and approach detection (Approach-Vu™) features
• Optional coded horn override and other control enhancements available

How It Communicates

• Visual indications: green = safe to enter, red = unsafe; Pedestrian-Vu™ projects blue inside trailers when motion is detected
• Controls actively inform material handlers and truck drivers when interlocked in a safe operating sequence

Connected/Analytics Capabilities

• Integration with digital platforms delivers real-time alerts for unsafe behaviors (overrides, fault modes, unrestrained trailers, open dock doors without deployed barriers)
• Productivity analytics: loading duration, bottleneck detection, equipment utilization and trailers at dock without restraint engagement
• Uptime and service data: connected equipment state, service history, trending and event logging

Technical specifications

• NEMA 4X rated Dok-Lok® style user interface (membrane switch buttons) for corrosive and harsh dock environments
• Interior traffic-style and exterior lights are UL listed and use energy-saving LED modules
• Designed to withstand windblown dust, rain, splashing water and similar harsh conditions
• Traffic-style configuration: manual three-position toggle switch for stop/go/neutral signaling
• System components: inside communication/control box, outside signal lights, interior/exterior instructional signage
• Color conventions: green = safe to enter, red = unsafe to enter, blue = Pedestrian-Vu™ active loading verification
• Interlock capable with Dok-Lok® vehicle restraints and integration with Corner-Vu™, Leveler-Vu™, Pedestrian-Vu™, Approach-Vu™ and Lok-Vu™
• Supports incremental deployment: standalone components or full Dok-Lok® Style Light Communication System
• Options include coded horn override and digital connectivity for analytics and alerts
