Reduce troubles during boom and arm replacement! Efficiently and cleanly disassemble and assemble large demolition machines and high-altitude demolition machines!

High surge flow (rapid changes in flow rate) is the most common reason for screw-type couplings to fail in harsh applications. Previous solutions involved using oversized couplings that were expensive and bulky. However, that is no longer necessary. The TLX flat-face twist-lock quick-connect coupling is designed to handle the highest surge flows and pressure fluctuations. A new 3/8" model (TLX 307) is now available. Made of high-alloy steel and coated with zinc-nickel plating, it ensures long life even under severe conditions. Sizes range from 3/8" to 1 1/2", making it suitable for most applications.

Japan is one of the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of major earthquakes occurring. Regarding the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake countermeasures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" For more details, please download the materials or contact us.
