Description

[Detailed Description of the Invention] The present invention relates to a device for fixing mineral crushed to the lifting frame of a long saw machine using a plate wedge, and its purpose is to fix mineral crushed into the lifting frame of a long saw machine. Then, by tightening the plate wedges inserted into the wedge grooves of the pair of clamps in the lifting frame, the crushed mineral can be fixed firmly and reliably easily and quickly, and by simply pulling up the plate wedges. , it is possible to easily and quickly release the locking of mineral crushing.
