Ronk List of Products and Services

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." With one transmission unit, the workers' receivers can be "infinitely expanded," and the system can operate with "up to 5 transmission units" at the same site.

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, allowing for longer detection distances and fewer false activations compared to ultrasonic methods. ● When the distance falls below a set threshold, the warning light alerts with sound and light. ● The warning light and sensor are magnetically mounted, making it easy to install in locations with lift switches, such as inside the cabin or basket. **Laser Detection Distance** 0.1m to a maximum of 10m Configurable caution/danger distance settings Based on information from the sensor, it provides warnings with different sounds and lights according to the set distance. Safety Distance: Warning light is off Caution Distance: Warning light flashes blue + intermittent warning sound Danger Distance: Warning light flashes red + intense warning sound

• IoT

This is a collision prevention alarm system that detects obstacles such as the upper part (tip) of the crane and structures using an "ultrasonic sensor." 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: 5 meters It is possible to set caution and danger distances. Depending on the set distance, the driver can be warned with different flashing lights and warning sounds from the patrol light. Safe distance: Patrol light off Caution distance: Blue flashing patrol light + intermittent warning sound Danger distance: Red flashing patrol light + intense warning sound

• IoT

※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 user with an alarm 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 available! It is possible to manage the usage status of the harness notify via PC or smartphone. Data can be collected from the history. Safety education can be conducted for workers not using harnesses in hazardous areas.

This is a collision prevention alarm system that detects obstacles such as structures using an "ultrasonic sensor" on the upper part (tip) of the aerial work platform. The "ultrasonic sensor" and "control box" installed on the upper part (tip) of the aerial work platform are charged by a solar power system, eliminating concerns about battery depletion and making them "unnecessary to remove." *The control box on the driver's side and the control box on the upper part (tip) of the aerial work platform are wirelessly connected, so there is no worry about disconnection during the crane's movement and extension.
