Abstract

A work machine whose exhaust device includes a first exhaust device, a second exhaust device, and a third exhaust device. The first exhaust device and the third exhaust device are arranged side by side with their respective one ends facing the same direction. The second exhaust device faces the other end side in the same direction as one end side of the first exhaust device and the third exhaust device, and is arranged side by side with the first exhaust device and the third exhaust device in plan view. It is arranged between the first exhaust device and the third exhaust device, and is arranged above the first exhaust device and the third exhaust device in side view.

Description

technical field [0001] The present invention relates to work machines such as wheel loaders. Background technique [0002] In working machines such as a wheel loader and a hydraulic excavator, an engine, an auxiliary machine of the engine, and the like are disposed in a machine room partitioned by a structural cover. Examples of auxiliary machines of the engine include a radiator for cooling the engine, an exhaust device for treating exhaust gas discharged from the engine, and the like. In these auxiliary machines, the exhaust device is disposed above the engine in the engine room (see Patent Document 1). [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Laid-Open No. 2013-104394 [0006] In the work machine described in the above patent document, an oxidation catalyst and a DPF (Diesel Particulate Filter: Diesel Particulate Filter) are provided as an exhaust device. In order to cope with exhaust gas restrictions in rece...
