とする高所作業車に於けるバケツトの昇降装置。 A bucket that can be raised and lowered is disposed at the tip of the boom via a predetermined connecting means, and a tube side that is associated with the boom and the bucket so as to be slidable up and down following the lifting and lowering movement of the bucket is located below, and A cylinder is arranged in which the rod side having a fixing point near the top is located upward, and the stroke length of the rod is approximately 1/2 of the lifting stroke width of the bucket, and one end is connected to the boom between the boom and the bucket. a main chain that winds around a sprocket that is fixed and placed at the lower end of the cylinder, and whose other end is fixed to the same part as the rod of the cylinder; and a main chain that has one end fixed to the boom and winds the sprocket that is placed at the lower end of the cylinder. A subchain whose other end is fixed to the same part as the rod of the cylinder with an elastic material interposed therebetween, and a subchain whose one end is fixed to the boom and which is wound around a sprocket installed at a slightly upper side of the cylinder. A lowering chain fixed near the bottom of the bucket is disposed so that the expansion and contraction movement of the rod of the cylinder is transmitted to the boom and the bucket via the rod and the plurality of chains. A device for lifting and lowering buckets in work vehicles.
