A hydraulic crusher uses a hydraulic cylinder to rotate a pair of crushing arms rotatably attached to a frame to statically crush concrete or the like held between the two arms.

アタツチメントの交換が行いにくくなる。 However, with this type of crushing arm shape, even when the arm is fully closed, a space remains inside.
Concrete lumps attached to reinforcing steel etc. get stuck in this space, making it extremely difficult to perform small-splitting work. For this purpose, an attachment for slicing or cutting is fixed to the inside of the crushing arm to carry out the work. Since the attachment is fixed to the crushing arm by inserting a bolt or pin into the crushing arm, a force in the shearing direction is applied to the bolt or pin, causing it to easily bend or break. In addition, bolts and pins constantly collide with concrete and reinforcing steel during work, so they quickly become deformed.
It becomes difficult to replace attachments.

An object of the present invention is to provide an attachment that is robust and easy to attach and detach. The attachment consists of a set of substantially U-shaped members with flat plates at the ends, bolts that connect the flat plates, and a dividing or cutting member fixed to the inner U-shaped member, and a protrusion on the crushing arm. The above problem is solved by surrounding and mounting the arm in the valley between the two.
