FIELD: mechanical engineering.
SUBSTANCE: invention refers to digging machines, specifically to attachments of one-bucket hydraulic excavators with quick-release devices for attachments change. Equipment for hydraulic excavator includes handle, bucket, mounting pins, tie rod, swiveling lever, grippers and hydraulic control cylinder. The swiveling lever is pivotally connected with tie rod and mounting pins are pivotally mounted on the handle and free end of the tie rod and interconnected via hydraulic cylinder in the rod end of which spring is installed. On the rear wall of the bucket there are eyes with stationary gap-shaped grippers for fixing the mounting pins.
EFFECT: simplification of quick-release device design.
