A Safe and Reliable Solution for Operator Interaction in
Factory and Machine Environments
The Thumb-Up Safety LED Display is a two-way confirmation safety system designed for construction sites. It helps prevent potential hazards such as accidental entry or misoperation between workers and heavy machinery by establishing a clear visual and audible communication mechanism.
The Thumb-Up Safety LED Display combines physical separation, signal confirmation, and feedback to form a closed-loop safety system between operators and workers, effectively reducing on-site safety risks.

Working Temperature
When the vehicle is in operation, the safety shield displays a red LED, prohibiting approach. Workers in the safe zone can signal a thumbs-up to request permission to enter the work zone.
Upon seeing the thumbs-up gesture, the operator will stop the vehicle and press a button inside the cab to activate the green LED thumbs-up display.
Once the green LED thumbs-up display is activated, accompanied by an audible warning — Safe to pass now (customizable message supported), the worker is permitted to safely approach the vehicle.
After the worker finish his communication with the operator and back to the safe zone, the operator will press the button again to activate the red LED thumbs-up display, accompanied by an audible warning — Danger, please stay away (customizable message supported).
THE DIGITAL THUMBS UP PROCEDURE
When the machine is in operation, the protective sign installed outside the cab will automatically illuminate a red LED light, warning you not to approach.
When you want to approach the machine, give a thumbs-up to the operator within a safe distance to request permission to enter their work area.
Once the operator sees you and confirms that it is safe, they will stop the machine and press the button inside the cab to activate the “Thumb-Up” signal light.
The external indicator will subsequently switch from red to green while emitting an audio instruction, permitting you to approach the machine safely.
