A team of experienced ground professionals provides total support from the designer's perspective.

The ground business services of Inhabitant Business provide a one-stop solution from investigation to construction and warranty. We conduct ground surveys, analyze and determine results, prepare construction estimates, and then provide reinforcement work to the client. We also offer ground warranty as aftercare. We respond through a network of 74 ground companies nationwide. The ground assessments from partner companies are double-checked by ground engineers from Inhabitant Business (automatically providing a second opinion). Additionally, ground warranty is automatically included. There are no exemptions due to slope angles, and we also address ground accidents caused by retaining walls; it is applicable to non-residential properties as well. This is a top-class ground warranty in the industry.

Therefore, our company will provide assistance with structural calculations (allowable stress calculations). Additionally, if our internal capacity for wall quantity calculations (frame calculations) is saturated, please feel free to consult with us.

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.

[To the owners of parking lots and parking lot construction companies] "I'm worried about not colliding with pedestrians when exiting the parking lot..." Among vehicle entrances to parking lots, stores, residences, and factories, particularly at entrances facing sidewalks or roadways, there is a risk of dangerous incidents such as collisions with pedestrians or between vehicles. To alleviate such concerns, Hotron proposes a [Vehicle Exit Warning Sensor] that detects vehicle departures using various sensors 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." *Please note that a separate control panel is required to include the controller and switching power supply (24V) when using the exit warning system. *We kindly ask customers to arrange for the switching power supply (24V), LED rotating light, control panel, circuit breakers, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances. We hope this will contribute to safer vehicle passage for everyone. ◎ For more details, please contact us or download the catalog.
