Abstract:
An hydraulic shovel according to the present invention includes a lower running body 1, an upper turning body 3 turnably mounted on the lower running body 1, a boom 4 pivotably attached to the upper turning body 3, an arm 5 pivotably attached to the boom 4, a bucket 6 attached to the arm 5, an boom angle sensor S1 which detects a condition of the boom 4, an attachment condition determining part 300 which determines whether the boom 4 is within a predetermined upper working range based on a detection value of the boom angle sensor S1, and an operating condition switching part 301 which switches an operating condition of the hydraulic shovel. The operating condition switching part 301 slows down a movement of the bucket 6 if the attachment condition determining part 300 determines that an attachment is within the predetermined upper working range UWR.
