What does "returning to nature" greening aimed at by Rontai mean?

ロンタイ ロンタイ
Hello everyone, nice to meet you. My name is Sekiguchi from the Osaka branch. Without further ado, at Rontai, we value "early greening." One reason for this is "disaster prevention." By using fast-growing non-native grasses, we achieve early greening and prevent erosion of slopes. Next is the creation of an "environment" that allows the original plants to return easily. While preventing slope erosion, we also create a suitable environment for plant growth. This is a photo taken two years after the construction of the RONKET DX3 type during disaster recovery work. This is not a photo showing failure in greening. If you look closely at the slope, you can see young trees like camphor trees growing vigorously. The vegetation is transitioning from the non-native grasses introduced for early greening to local trees. Early greening is also contributing to the creation of an environment that "returns to nature" from a long-term perspective. The progress from the completion of construction to early greening is posted on our company website, so please take a look there as well.

When the sensor detects a car, it notifies pedestrians of the car's departure with the light of a rotating beacon!

Perfect for entrances and exits of parking lots and stores! Notify pedestrians of vehicle departures with the light from the rotating lamp! Here is a proposal for a departure warning sensor!

  • CATALOG

[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.
