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.
CONSTITUTION: A piston 8 with a rod 9 is provided in the main body 6 of a cylinder, while oil-feeding ports 13 and 15 being provided at a passage 12 connecting the piston 8 in the main body of the cylinder with a chamber A on the side of a base part and at a passage 17 connecting the piston 8 with a chamber B on the side of the tip. 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.
