※Visualization of safety belt usage ⇒ Habit formation ⇒ Prevention of fall accidents A wireless switch that can be retrofitted to existing safety belts detects the usage status of the harness! When it detects that the hook is not in use, it alerts the individual and simultaneously sends data to the cloud, enabling remote monitoring by administrators. Usage logs are recorded in one-minute intervals. Workers receive audio and visual warnings by attaching a wireless receiver to their helmets. **The areas and ranges where alarms are needed can be set with area sensors! By combining multiple area sensors, it is possible to set up complex alarm locations. The rotary switch of the area sensor allows for the setting of alarm ranges. ***History management via PC or smartphone (optional) is also possible! It is possible to manage the usage status of the harness notify system via PC or smartphone. Data can be collected from the history. Safety education can be conducted for workers not using harnesses in hazardous areas.

Follow Me is a guiding light that visually prompts drivers about necessary lane and traffic regulation conditions due to various situations such as road construction, accidents, and traffic time zones. It allows for real-time setting changes and can immediately respond to the constantly changing regulation content, helping to prevent accidents, enhance safety measures, and alleviate traffic congestion. Everything is wireless, making installation easy. It can also flexibly accommodate changes and expansions. The light management tool allows for various settings and management of the lights. ● Unlimited installation units ● Automatic synchronization ● Equipped with 3D sensors *Options* Medium-sized integrated solar unit for temporary use Large separate solar unit for temporary use Message Bluetooth integration ⇒ Notifies nearby workers via a wristwatch-type terminal with "vibration and text messages" in case of light tipping over.

Prevent contact and pinching accidents between tunnel inspection vehicles, aerial work platforms, vertical lifts, and superstructures!! Laser sensors mounted on the buckets of aerial work platforms measure the distance to the ceiling and wirelessly send data to a warning light. ● Uses fine laser beams, providing a longer detection range and fewer false activations compared to ultrasonic methods. ● When the distance falls below the set threshold, the warning light alerts with sound and light. ● The warning light and sensor are magnetically mounted, allowing for easy installation in locations with lift switches, such as inside the cabin or basket. **Laser Detection Range** 0.1m to a maximum of 10m Settings for caution distance/hazard distance are possible. Based on information from the sensor, it warns with different sounds and lights according to the set distance. Safe distance: Warning light is off. Caution distance: Warning light flashes blue + intermittent warning sound. Hazard distance: Warning light flashes red + intense warning sound.

This is a collision prevention alarm system that detects obstacles such as structures using an "ultrasonic sensor" on the upper part (tip) of the crane. The "ultrasonic sensor" installed on the upper part (tip) of the aerial work platform is integrated with a solar rechargeable battery, eliminating concerns about battery depletion and making it "unnecessary to remove." Up to four ultrasonic sensors can be added. *The rotating light unit on the driver's side and the ultrasonic sensor on the upper part (tip) of the crane are wirelessly connected, so there is no worry about disconnection during the crane's movement and extension. The driver is warned by the light and buzzer sound of the rotating light unit. **About Ultrasonic Sensor Detection** Maximum detection range: 5m Settings for caution distance/danger distance are possible. Depending on the set distance, different warning lights and sounds can alert the driver. Safe distance: Rotating light off Caution distance: Blue flashing rotating light + intermittent warning sound Danger distance: Red flashing rotating light + intense warning sound

This is a bidirectional proximity warning system that detects the approach of heavy machinery and workers using "ultrasound" and "radio waves." The heavy machinery operator is alerted to danger through "sound" and "light," while the workers are notified through "vibration" and "sound." One transmission unit can support an "unlimited number of worker receivers," and up to "five transmission units" can be operated at the same site.
