Efficient lifting operations are possible with shortening (length adjustment function)!
This is a master link with a shortening function specifically designed for double lifting, capable of handling loads from 1.5t to 13.8t (within a usage angle of 90 degrees). With just this one master link, you can adjust the length of any chain to the optimal lifting height. The method is simple: just hook the chain into the length adjustment pocket located at the bottom of the product to change the length. This allows for the balanced lifting of unbalanced loads (eccentric loads).

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.
