Efficient lifting operations are possible with shortening (length adjustment function)!
This is a master link with a shortening function specifically for double lifting, compatible with a load range of 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 you to lift unbalanced loads (eccentric loads) in a balanced manner.

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 Swedish company Gnebo's lifting equipment 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 with innovative products, and we have now acquired general agency rights for 10 European companies, responding to user needs not only as an import trading company but also from the perspective of a Japanese manufacturer, 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, and we have reached a point where we conduct the entire process of 'design', 'manufacturing', and 'product inspection' for some products in-house. Leveraging the 'proprietary technology' we have cultivated over many years, we are committed to further developing products that satisfy our customers.
