Side lifting, which is prohibited with eye bolts, is now possible! The load when using multiple units is also clearly defined!!
The Martec Frenno Link Bolt is a next-generation eye bolt type lifting device that can rotate freely 180 degrees relative to the mounting surface and 360 degrees relative to the mounting axis. It can be safely used for lifting heavy objects, horizontal lifting, and inversion work, which are prohibited with conventional eye bolts. It is actively used in various sites, including lifting operations for molds and concrete secondary products, as well as in major factories and general contractors. 【Features】 ○ After tightening the bolt to the specified torque on the target object, it can be safely lifted from any direction. ○ It is an all-direction type that can be safely used for lifting heavy objects and horizontal lifting work, which are prohibited with conventional eye bolts. ○ It has more than three times the strength compared to JIS eye bolts, allowing for smaller screw holes in the target object. ○ Depending on the application, we offer a rich lineup that meets customer requests, including non-lubricated washers, bearings, hex socket bolts, seated washers, and wide-angle oscillation. ◆ We can also accommodate special specifications for screw sizes (inch sizes, fine-thread screws) and electroless nickel plating! ◆ ○ All-direction safety factor of 5 or more.

Company information
Martech Co., Ltd. was established in April 1974 as a company engaged in the inspection and supervision of newly built ships, and nearly 50 years have passed since then. Four years later, in 1978, we became the general agent for the import of lifting equipment from the Swedish company Gnebo and began sales. Our unique ideas and extensive product range, which include materials and shapes not available in Japan, not only meet customer needs but also continuously contribute to the 'safety', 'labor-saving', and 'convenience' of production sites. Since then, we have expanded our dealings with overseas suppliers that offer innovative products, and we have now acquired general agency rights for 10 European companies. We have responded to user needs not only as an import trading company but also from the perspective of Japanese manufacturers, covering everything from product promotion to safe supply and quality assurance. In 2001, we established our headquarters factory and began manufacturing safety components for construction machinery manufacturers. We have reached a point where we handle the entire process of 'design', 'manufacturing', and 'product inspection' for some of our products in-house. Leveraging the 'proprietary technology' we have cultivated over many years, we are committed to further developing products that will satisfy our customers.
