Abstract:
A hydraulic excavator includes a lower travel body, an upper swivel body, a cooling unit, and first and second exterior members. The cooling unit includes a first cooling device disposed facing the first exterior member, and a second cooling device disposed on a side of the first cooling device towards the second exterior member and in midway in an air channel between the second exterior device and a cooling fan. The second cooling device extends in a direction intersecting a direction in which the first cooling device extends. The first and second exterior members have first and second openings in portions that overlap the first and second cooling devices in a height direction, respectively. A lower edge of one of the first opening and the second opening disposed at a higher position is positioned higher than an upper edge of the other of the first opening and the second opening.
