Therefore, there is a concern that the exhaust gas purification device may vibrate in a manner exceeding the permissible acceleration of various sensors mounted on the filter of the exhaust gas purification device and the exhaust gas purification device.
In addition, due to the increase in auxiliary equipment mounted on work machines such as superchargers and EGR coolers, it is difficult to mount the bracket for fixing the exhaust gas purification device to the engine in the limited space of the vehicle body.

A work machine having: a frame of the work machine; an engine supported by the frame in a machine room of the work machine; Substances; a hatch that divides the machine room; a support part of the hatch cover is a part that supports the hatch cover and is provided on the frame; the engine cover has: a roof covering the machine room above the engine, in order to purify the exhaust gas The device is taken out from the machine room upward and is provided in the opening of the ceiling plate, and the reinforcement member is arranged on the peripheral edge of the opening to bear the supporting load of the exhaust gas purification device, and the hood is supported by at least the hatch cover support member; through the opening An exhaust gas purification device support member that supports the exhaust gas purification device in a downwardly suspended manner; and an opening cover that can be detachably attached to the engine hood to close or open the opening, and the exhaust gas purification device support member has: the exhaust gas purification device. and a fixing portion supported and fixed to the reinforcing member. When the fixing of the fixing portion is released, the exhaust gas purifying device supporting member can be detached upwards of the opening together with the exhaust gas purifying device mounted on the mounting portion.
Description
technical field [0001] The present invention relates to work machines such as wheel loaders. Background technique [0002] In a work machine such as a wheel loader or a hydraulic excavator, an engine or an auxiliary machine of the engine or the like is disposed in a machine room partitioned by a hatch cover. As an auxiliary machine of the engine, for example, a radiator for engine cooling, an exhaust gas purification device having a filter for trapping particulate matter contained in exhaust gas discharged from the engine, and the like can be cited. Among these auxiliary machines, the exhaust gas purification device is fixed to, for example, a mount attached to the engine (see Patent Document 1). [0003] prior art literature [0004] Patent Document 1: Japanese Patent Laid-Open No. 2010-138832 [0005] In the case of fixing the exhaust gas purification device on the support mounted on the engine as in the working machine described in the above-mentioned patent documents,...
