Abstract

PURPOSE: To facilitate the change-over of a front loader optionally to single-moving or plural-moving lift-type loader as well as the operation for change-over by using one kind of a cylinder.

Moreover, these passages 12 and 17 are communicated with each other, while in the communicating part of both passages being provided a check valve mechanism checking the flow in the direction from the chamber A to the chamber B and a mechanism opening or closing the communicating part. By using a cylinder b for single and plural use thus constituted, a lift arm is vertically moved.
