Document Type and Number:
WIPO Patent Application WO/2014/181490
Kind Code:
A1
Abstract:
Provided is a hydraulic shovel such that it is possible to dispose a cooling device in the vicinity of a cab rear wall without compromising the performance of the cooling device. A cab rear wall (20) includes an upright wall section (21) that extends in the vertical direction, and an inclined wall section (22) that is connected to the upper edge of the upright wall section (21) and inclines upwards and to the rear from the upper edge of the upright wall section (21). The outer surface of an oil cooler (60) that serves as a cooling device includes a front surface (66) that faces the upright wall section (21) and extends in the vertical direction, and an inclined surface (67) that is connected to the upper edge of the front surface (66) and inclines upwards and to the rear from the upper edge of the front surface (66). The inclined wall section (22) has one edge that is connected to the upright wall section (21) and another edge on the opposite side from the one edge, and the upper edge of the front surface (66) of the oil cooler (60) is positioned lower than the height of the other edge. The angle (α) formed by the upright wall section (21) and the inclined wall section (22) is greater than or equal to the angle (β) formed by the front surface (66) and the inclined surface (67).
