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..."

[To the owners of parking lots and parking lot construction companies] "I am worried about the possibility of colliding with pedestrians when exiting the parking lot..." Among vehicle entrances to parking lots, stores, residences, and factories, those particularly facing sidewalks or roadways are expected to pose risks of dangerous incidents such as pedestrian collisions and vehicle-to-vehicle accidents. To alleviate such concerns, Hotron proposes a [Vehicle Exit Warning Sensor] that detects vehicle departures at various sites and alerts the surrounding area with LED lights and buzzers. The system consists of a simple configuration of "Sensor" + "Controller" + "Switching Power Supply (24V)" + "LED Rotating Light." *When using the exit warning system, we kindly ask that you arrange for the switching power supply (24V), LED rotating light, control panel, circuit breaker, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances. [Contents Included] ○ Exit Warning System Configuration ○ Comparison Table of Exit Warning Sensors ○ Four Modes ○ Wide Range of Applications ○ Customer Feedback ○ Appearance Diagram / Specifications ◎ For more details, please contact us or download the catalog.
