We will be exhibiting at EE Tohoku '23 starting tomorrow!

An evolved hydraulic tensioner that overcomes the challenges of conventional tensioners, such as "too heavy," "does not fit in narrow spaces," and "oil leakage due to repeated use."

The hydraulic bolt tensioner from "Boltight," a member of the Nord-Lock Group, was born as an evolved version re-invented by the engineer Fred Heaton, who developed the tensioner itself, to overcome the challenges faced by the tensioner. These challenges include common disadvantages of hydraulic tools like tensioners, such as being "too heavy and difficult to work with," "leaking oil after repeated use," and "not being installable in confined spaces." All of Boltight's tensioners have been significantly lightweighted to the extreme, using in-house developed bridges and seals to greatly reduce the weight of the tensioner. Additionally, the durability for repeated use has been greatly improved with technologies such as in-house developed seals. Furthermore, we can flexibly customize the shape and size for areas where space constraints prevent application, delivering them with the same lead time as standard products.

Can be used as a replacement for existing pins. It significantly reduces the maintenance costs of equipment and is an innovative pin product that can be used universally on any moving part.

Wear occurring in movable parts is a major enemy of low-cost operation, requiring regular maintenance such as bush replacement and pin hole repair. For equipment manufacturers, it is an issue that cannot be overlooked, as it increases maintenance costs, which are a quality indicator of the machine, and shortens product lifespan. For machine users, it leads to chronic problems of high maintenance costs and downtime. The advantage of the Expander System is that it can be used semi-permanently and completely prevents wear in movable parts, eliminating the need to replace bushes like consumables. In movable parts that do not use bushes, it can eliminate oval deformation. The secret lies in the fact that after installation, the pin's axis expands in a way that completely seals the gaps inside the pin hole. The Expander System is already widely adopted by leading construction equipment manufacturers, including Japanese companies, and has passed a continuous field durability test of 60,000 hours without any loss of functionality at Volvo Construction Equipment. It comes with a lifetime warranty, guaranteeing the product's functionality until the first removal. *For more details, please download the catalog or feel free to contact us.

No allowance for loosening, securely maintain axial force! Physically prevent loosening of bolts/nuts.

This catalog introduces the "Nord-Lock Washer," which utilizes wedge-locking technology that physically prevents bolt loosening without relying on friction. It features the "Nord-Lock X Series Washers," which simultaneously prevent two types of loosening, as well as the "Nord-Lock SC Washers," designed for high-strength bolts used in construction. Additionally, it includes information on why bolts loosen and the Nord-Lock customer magazine.

An innovative product that can tighten enormous bolts and nuts that cannot be tightened by human strength using just one torque wrench.

A mechanical bolt tensioner developed in 1984 at the request of US Steel, the largest steel company in the United States. By distributing the enormous torque required to tighten large-diameter bolts into smaller torques, it dramatically improves work safety. Additionally, it achieves remarkably accurate fastening force, allowing for work in high or confined spaces without issues. The use of electric tools and air tools further shortens work time, dramatically reducing downtime caused by operations and enabling low-cost operations. 【Features】 ■ Amazing axial force accuracy due to patented structure (over three times the accuracy of conventional methods) ■ Large-diameter bolts can be fastened with just one torque wrench ■ Does not depend on the skill of the operator, ensuring accurate fastening force regardless of who performs the work ■ Incredible axial force precision prevents loosening even under severe vibrations ■ Strong against loosening that does not involve return rotation due to thermal cycles, thanks to elastic fastening ■ Usable without issues in confined or elevated spaces *For details, please refer to the catalog or contact Nord-Lock Japan. *Beware of imitations that resemble the appearance. They do not have equivalent functions due to patented technology. Nord-Lock Japan also provides various technical support. Please feel free to consult us.

Protech Engineering will exhibit at the "Landslide Disaster Prevention Technology Forum '25 in Toyama," organized by the Japan Society for Slope Disaster Prevention Technology, scheduled to be held on Thursday, October 9, 2025. On that day, we will provide detailed explanations of the following disaster prevention products using models, panels, and various materials. ◆Exhibited Products◆ - Pile-type debris flow and driftwood countermeasures for non-flowing streams / Urban Guard (model display) Additionally, our representative will conduct a technical presentation, so we kindly invite you to attend.

Protech Engineering (Booth Number: 240) will be exhibiting at the "Hokkaido Construction Development Comprehensive Exhibition 2025," scheduled to be held on October 8 (Wednesday) and 9 (Thursday), 2025. On the day of the event, we will provide detailed explanations of the following disaster prevention products using models, panels, and various materials. ◆ Main Exhibited Products ◆ - Energy-absorbing rockfall protection fence / ARC Fence (model display) - Landslide debris protection fence / Slope Guard Fence Type LE (model display) - Pile-type (pile foundation) debris flow and driftwood countermeasure for non-flowing streams / Urban Guard - Avalanche prevention piles / Tri-Pile - Avalanche protection fence / Slope Guard Fence Type LS - High energy-absorbing rockfall protection fence / Macro Fence In addition, we will have a variety of materials on disaster prevention products developed independently by Protech Engineering, so we kindly invite you to visit our booth.

Profect Co., Ltd. will hold a seminar on October 3rd (Friday) themed around the IT Implementation Subsidy 2025 and our developed and sold production management system "TED." This year's IT Implementation Subsidy has seen a significant decrease in the acceptance rate compared to previous years. Many companies are struggling with the situation of having wanted to implement IT tools but being rejected. In this seminar, we will explain why the acceptance rate has dropped, the background behind it, and the key points for being accepted. Additionally, we will introduce our initiatives that have achieved a 100% acceptance rate so far this year and the reasons why our production management system "TED," registered as an IT tool, is chosen. To accommodate busy schedules, this seminar will be held in a hybrid format, allowing for both in-person attendance and online participation via Zoom. Please choose your preferred method of participation according to your convenience. If you are currently considering applying for the IT Implementation Subsidy or are interested in production management, we encourage you to join us. We sincerely look forward to your application.

An international forum aimed at promoting the circular economy and closed-loop economy, "Closed Loop Recycle Forum 2025 (hereinafter referred to as CLRF2025)," will be held for two days from November 25 (Tuesday) to 26 (Wednesday) at The Oriental Terrace in Chuo Ward, Hamamatsu City, Shizuoka Prefecture. In Europe, closed-loop recycling practices are already advancing. We have organized this international forum as a platform to connect the forefront of Europe with Japan's challenges, striving for a future that balances economic viability and environmental sustainability. A total of 12 speakers, including Chairman Kajiwara of the Waste and 3R Research Foundation and Director Kaneko of the Ministry of the Environment's Container and Packaging Recycling Division, along with leading recycling operators and researchers from Japan and Europe, will present advanced examples of the circular economy and closed-loop economy. Furthermore, through discussions on the feasibility and challenges of implementation in Japan, we will explore hints for sustainable business models that companies and local governments should aim for.
