The "Safety Walker" installed on the premises of a famous leasing company in Okayama Prefecture to suppress falling debris such as fallen leaves. A grating that is less likely to clog.

Okagreat Co., Ltd.'s "Safety Walker G·D" and "Safety Walker L·D" are designed to be less prone to clogging from small stones and debris compared to traditional grating. They also suppress falling leaves and other debris, maintaining hygiene, enhancing appearance, and being resistant to damage due to their surface material structure, making them an "evolved grating." They are suitable not only as site-cast grating but also for various drop-in types, bolt-fixed types, raised types, and other special-sized covers (please consult us for concrete precast products, etc.). Due to their structural design, the surface is made of material, making them strong against twisting and impacts from vehicle tires, ensuring that the grating is difficult to break. They are also ideal for preventing grating damage. Additionally, the design minimizes the accumulation of stones and debris in the grating itself, preserving the landscape. Multiple slit holes are made in the surface "striped steel plate" or "patterned steel plate," balancing drainage and strength. Furthermore, it has been reported that the slip resistance exceeds that of traditional types. You can experience the difference from traditional grating with issues such as "leaves falling into the gutter making cleaning difficult..." or "the grating frequently breaking near the entrance..."

These products can be used not only as site-cast grating but also in various drop-in types, bolt-fixed types, raised types, and other special dimension covers (please consult us for concrete secondary products, etc.). Due to their structure, the surface is made of material that is strong against twisting and impact from vehicle tires, making the grating difficult to break. They are also ideal for preventing grating damage. Additionally, the structure makes it difficult for stones and debris to clog the grating itself, preserving the aesthetic appeal. Multiple slit holes are made in the "striped steel plate" or "patterned steel plate" on the surface to balance drainage and strength. It has also been reported that the slip resistance exceeds that of conventional types. You can clearly notice the difference when passing through areas where grating frequently breaks, such as near entrances, especially when using golf carts. You will experience the difference compared to conventional grating.

Are you struggling to explain "safety" to the client using just drawings? • The risks in blind spots are difficult to convey to the client through drawings alone. • Safety measures often become a target for cost reduction, making it hard to communicate their necessity. • There is a concern that the client might say, "It's more dangerous than I thought," after completion. Risks that are clear to design professionals are not easily understood intuitively by clients who are outside the field. This document is not just a simple explanation of sensor functions; it is a guide to visually explain "why sensors are necessary in those locations." It can be used directly as explanatory material for clients. Here are three key points for utilizing this document: 1. Visualization of Risks Blind spots during departure and contact risks within the site are illustrated clearly. 2. Clarification of Selection Criteria A comparison table outlines the differences between complex sensor types such as infrared, ultrasonic, and loop coils. 3. Diagram of System Configuration It illustrates not just the sensors alone, but how they are combined with rotating lights and control panels, providing practical assistance for electrical equipment design. Please make use of this to prevent "rework after completion" and "accident risks."

In facilities operating nurse call systems, we have made bed exit sensors wireless, allowing them to notify in conjunction with the nurse call system. By simply connecting the mat sensor "Foldable Thin Matt-kun," the body movement call "Ugo-kun," and the wheelchair body movement call "Ayumi-chan" to the transmitter HB-RS, you can make the bed exit sensor wireless. The infrared sensor "Just Place Pole-kun" has the transmitter HB-RS built-in. This helps prevent accidents caused by falls, slips, or wandering, contributing to the efficiency of medical operations. 【Features】 ○ Wireless conversion by simply connecting existing sensors to the transmitter HB-WSK. ○ Bed exit sensors notify wirelessly in conjunction with the nurse call system. ○ Up to 5 transmitters can be registered with one receiver. ○ The communication distance between the transmitter and receiver is approximately 10 meters. ◎ For more details, please contact us or download the catalog.

We will update articles that answer questions like, "What kind of company is it?" "What is the atmosphere at the site?" and "Is it okay to leave it to you?" Specific examples of articles: ● Behind the Quality of Delivery Innovations in loading, considerations for routes, voices from the field, etc. ● Strengths of Askul Logist Why is the quality stable, and why are we strong in the Tokyo metropolitan area? ● Logistics Insights Useful for Shippers Hints for site improvement and how to respond when troubles occur. ● Initiatives with Existing Shippers Real examples of "what we are being evaluated for." We will provide "honest information" that is useful for sales, our colleagues on-site, and shipper companies.

We will introduce the implementation results of the sensor technology developed by the Hotron Group, which has been cultivated over more than half a century, through customer case studies. In addition to automatic door sensors, we also offer a wide range of vehicle detection sensors and nursing/care sensors. We have many implementation examples available, so please take a look at the case study page.

Full and empty management refers to the real-time display of parking availability and the management of efficient use of parking spaces. By utilizing Hotron's sensors, drivers can quickly discover available parking spaces, achieving efficient parking lot operations. ■ For large parking lots, the "floor management method" and "block management method," which focus on cost reduction, are recommended. Sensors are installed at regular intervals to count the number of vehicles passing through. This method offers the advantage of easy installation and low costs. 【Target Products】 - Vehicle Count Sensor CCS2 - Ultrasonic Sensor HM-UX2/UW2 ■ For smaller scale operations, the "space management method," which installs sensors in each parking space to display availability with high accuracy, is recommended. By ensuring accurate full and empty displays, it helps prevent unnecessary entry of new vehicles and enables safe parking lot operations. 【Target Products】 - Occupancy Detection Sensor HM-UX2/UW2 - Occupancy/Pass Detection Sensor HM-LC6 - Occupancy Detection Sensor HM-LC7/LC7-FLS - Occupancy/Pass Detection Sensor HM-S6 - Occupancy Detection Sensor HM-S8
