Claims5
A front loader comprising:
- a main frame standing erect in front of the travelling vehicle;
- a boom having a rear end thereof pivotably supported at an upper portion of the main frame to be vertically movable;
- a work implement pivotably supported at a front end of the boom to effect scooping and dumping operations;
- and
- an indicator device for indicating a posture of the work implement, the indicator device including:
- a guide tube extending along a longitudinal direction of the boom on a rear portion of the boom;
- a tube support mechanism provided on the rear portion of the boom, the tube support mechanism supporting the guide tube so that the guide tube is movable in an axial direction thereof;
- a boom interlocking link having a rear end thereof pivotably supported by the main frame and a front end thereof operatively coupled to the tube support mechanism so that the guide tube moves in an axial direction thereof in association with vertical movement of the boom;
- an indicator rod inserted into the guide tube to be movable in the axial direction of the guide tube;
- a rod support mechanism provided at a longitudinal intermediate portion of the boom for supporting the indicator rod so that the indicator rod is movable in an axial direction thereof;
- and
- a work implement interlocking mechanism for interlocking the bucket and the rod support mechanism so that the indicator rod is movable in the axial direction thereof in association with the scooping operation and the dumping operation of the work implement;
- wherein the indicator device is configured to indicate that the work implement is in an identical posture irrespective of a height position of the work implement, by aligning a rear end of the indicator rod with a rear end of the guide tube.
