This system utilizes RFID technology with radio waves and magnetic fields to detect whether "safety harness hooks are being used" within a designated area and alerts the site to encourage proper use of fall protection equipment by workers. Using an IoT system, the hook usage status at the site can be monitored from a remote office. ■ System Overview 1. Set up the "Area Setting Device" and "IoT Box" at the high-altitude work site. 2. Workers wear the "IC Tag-equipped Hook Holder" and "Hook Magnet." * These can be easily attached to commercially available safety harnesses (owned by the customer). 3. Install a remote monitor box at the site office. 4. Detect whether safety harness hooks are being used within the area; if not in use, an alert is issued. 5. At the site office, the PC monitoring screen allows for checking the number of people in the area and whether safety harnesses are being used or not. If there are users not utilizing the harness, an alert is issued from the PC. ■ Example of Utilization… Can be used in various high-altitude work sites. Site examples: Bridge construction, residential construction sites, rooftop work, tower structures, high-altitude work vehicles.

"I want to prevent unauthorized access," "I want to know who is currently in the area," "I want to check past access records." There is an increasing demand for such needs not only for security but also for safety. On the other hand, there may be many factories that have not implemented such systems for reasons like the following: - Authentication is cumbersome - Cannot authenticate when carrying luggage - High implementation costs including construction - Poor environment causing equipment to break - The system is complex and cannot be managed Yoshikawa Industrial's hazardous area access management system has been developed by addressing each of these on-site needs. We have developed not only the revolving gate but also the dedicated reader built into the housing in-house. If you are interested, please download the PDF or contact us.

When approaching the restricted area around an opening, an alarm will sound. In the work area, there are many places and things, such as openings and dangerous equipment, that we do not want people to approach. Even when we say, "Stay away!" people may unconsciously get closer. Even if barriers are set up to prevent access, individuals may casually climb over them and encounter danger. In such cases, communication among colleagues can be effective, but there may be times when people are unaware of dangerous behaviors or when working alone, making it impossible to alert others. The "Rope-like Proximity Alarm System" serves as an alarm on behalf of colleagues when someone approaches danger. By surrounding dangerous areas with a rope-like antenna and having workers carry tags, we can alert them to the proximity of dangerous locations and people. Since it is rope-like, it can be used linearly or to encircle hazardous areas, allowing for flexible responses. It can also be used in conjunction with the "Worker Proximity Detection System."

The "Worker Proximity Detection System" by Yoshikawa Industries supports the awareness of heavy machinery and workers, aiming to reduce the risk of contact. By installing a "detection device" on the heavy machinery and having the worker carry a "tag," an alarm will sound when the two come within a certain distance (which can be set). 【Features】 - One detection device can detect in 360 degrees (all directions). - The detection range can be set from 3m to 12m in 1m increments. - It detects by circumventing obstacles, so it also alarms for head-on approaches. - Alarms can be activated for both the heavy machinery and the worker (please choose a tag with alarm functionality). - It can be installed regardless of the manufacturer, type, or power source of the forklift (compatible with 12v/24v/48v). - The system and peripheral devices can be developed and customized according to customer requests. - With a variety of optional products, you can use it more comfortably! - By using the "Non-Detection Area Setting Device," you can designate the driver's seat as a "non-detection area." This allows for use without removing or turning off the tag, making it popular in environments where drivers change frequently.
