PURPOSE:To facilitate the accommodation operation and permit the perfectly automatic operation by previously teaching the boom angle, arm angle, offset starting angle, and the offset completion angle into a controller. CONSTITUTION:An arm 4 is supported through an offset arm 22 onto the top edge of a boom 6 pivotally supported in vertically turnable ways onto a turning base 12, and a bucket 1 is installed in turnable ways at the top edge of the arm 4. In turn, the boom 6 and the arm 4 are folded, and the bucket 1 can be accommodated onto the side of a cabin 2. Then, a boom operating lever, arm operating lever, and an offset pedal are manually operated, and the boom angle, arm angle, offset starting angle and the offset completion angle are teaching-inputted into a controller. Offset operation is carried out automatically at the teached position. |
