Heavy duty shear.

摘要

The object of the invention is to provide an attachment heavy duty shear of reduced weight. This shear has a single-row upper jaw (4) and a single-row lower jaw (1), with the upper jaw being driven by a built-in hydraulic cylinder (5a) to open and close with respect to the lower jaw. The forward end of the lower jaw has a 7-configured guide member for precluding a lateral displacement of the upper jaw in shearing. This construction provides for reduced overall weight and positive grip and shearing. <IMAGE>
