Primary Function: Bucket Curl (Rotation):
The cylinder's sole mechanical function is to extend and retract its rod.
This linear motion is translated into a powerful rotational force (torque) at the bucket, causing it to curl (close) or dump (open).
Retracting the Rod: Pulls the bucket link, forcing the bucket to curl inward towards the machine. This is the action used for digging, scooping, and holding material.
Extending the Rod: Pushes the bucket link, forcing the bucket to uncurl or dump away from the machine. This is the action used to release its load.
This 570-1989 bucket cylinder is used 390D 390F excavator.
