Abstract
A wheel loader comprises an engine, an exhaust gas post-processing device, an engine room, a top plate, a cooling room, a partition wall, and a drainage mechanism. The exhaust gas post-processing device is disposed above the engine in the engine room and includes a diesel particulate filtering device and a selective catalyst reduction catalyst device. The top plate has a sloping part with a height that decreases toward the rear, and a first ventilation part that includes a plurality of through-holes formed in the sloping part. The top plate defines an upper plane of the engine room. The cooling room accommodates a cooling unit and is disposed to the rear of the engine room, separated by the partition wall. The drainage mechanism is disposed below the first ventilation part, and configured to drain water entering the engine room from the first ventilation part to the outside of the engine room.
