Hyper CLT flooring panel

Noise-sensitive wooden flooring | Civil Engineering CLT "Hyper CLT Flooring"

  • NEW
  • PRODUCT

In civil engineering sites, plywood is used for temporary roads, access roads, heavy machinery work yards, and material storage areas. Steel plates are common materials, but they tend to produce metallic sounds during vehicle passage and installation/removal, which can be a noise issue in construction near residential areas, schools, and hospitals. Hyper CLT plywood is a civil engineering CLT material that utilizes wood CLT. As wooden plywood, it can be used for mud prevention, ground protection, and ensuring work pathways, and its natural and soft texture helps create a different site environment compared to metal plates. The 5×10 plate weighs about 230 kg, and the 5×20 plate weighs about 460 kg, making them lightweight and easy to handle even with small machinery, which reduces the burden of transportation, installation, and removal. Additionally, it is easy to use for proposals that consider glare reduction and environmental considerations, making it recommended for innovative public works. As a registered technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS "TH-250021-A," we can propose it to companies considering noise measures, wood, plywood, timber, civil engineering, and civil engineering CLT. It is also suitable for construction that emphasizes consideration for the surrounding area and for sites considering alternatives to steel plates. We also accept requests for materials and consultations on implementation. Please consider wooden plywood as an option for temporary plans that take into account urban construction and neighboring measures.

When the sensor detects the car, the rotating light will turn on.

Ideal for entrances and exits of parking lots and stores! Notify pedestrians of vehicle departures with the light from the rotating lamp! Here’s a proposal for a departure warning sensor! Free catalog available!

  • NEW
  • CATALOG

[To the owners of parking lots and parking lot construction companies] "I'm worried about not colliding with pedestrians when leaving the parking lot..." Among vehicle entrances to parking lots, stores, residences, and factories, those that face sidewalks or roadways are particularly prone to dangerous incidents, such as collisions with pedestrians or between vehicles. To alleviate such concerns, Hotron proposes a [Departure 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 departure 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 installed as an add-on, 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.

Metal Crack Repair: MS Method for Repairing Cracks and Fractures in Machinery Equipment

  • NEW
  • PRODUCT

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding methods for repairs can change the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" and "secondary damage." Hinode Waterworks Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for metal crack repairs without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material at all. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. For more details, please contact us or download the catalog.
