摘要： A hydraulic excavator is provided which can allow the cooling device to be arranged in proximity to a rear wall of a cab. The rear wall of the cab has an upright wall part extending in the vertical direction and an inclined wall part inclined to the rear upper side with respect to the upright wall part. The outer surface of an oil cooler has a front surface facing the upright wall part and extending in the vertical direction and an inclined surface inclined to the rear upper side with respect to the front surface. The upper edge of the front surface is arranged below the height position of the other edge of the inclined wall part. An angle formed by the upright wall part and the inclined wall part is more than or equal to an angle formed by the front surface and the inclined surface.
摘要翻译：提供一种液压挖掘机，其可以使冷却装置布置在驾驶室的后壁附近。驾驶室的后壁具有在垂直方向上延伸的直立壁部分和相对于直立壁部分向后上侧倾斜的倾斜壁部分。油冷却器的外表面具有面向直立壁部并且在垂直方向上延伸的前表面和相对于前表面向后上侧倾斜的倾斜表面。前表面的上边缘布置在倾斜壁部分的另一边缘的高度位置的下方。由直立壁部和倾斜壁部形成的角度大于或等于由前表面和倾斜表面形成的角度。
