要約
(EN)
A working machine is provided with: a frame for the working machine; an engine supported within the machine compartment of the working machine by the frame; an exhaust gas purification device having a filter for collecting particulate matter contained in the exhaust gas discharged from the engine; a compartment cover for defining the machine compartment; a compartment cover support member which is a member for supporting the compartment cover and which is provided on the frame; an engine hood supported by at least the compartment cover support member and having a top plate which covers the machine compartment at a position above the engine, an opening which is provided in the top plate in order to allow the upward extraction of the exhaust gas purification device from the machine compartment, and a reinforcement member which is disposed at the peripheral edge of the opening and which carries the load of the exhaust gas purification device; an exhaust gas purification device support member for supporting the exhaust gas purification device in such a manner that the exhaust gas purification device is suspended downward through the opening; and an opening cover removably mounted to the engine hood and closing or opening the opening. The exhaust gas purification device support member has a mounting section which is mounted to the exhaust gas purification device and an affixation section which is supported by and affixed to the reinforcement member. When the affixation of the affixation section is released, the exhaust gas purification device support member can be removed to a position above the opening together with the exhaust gas purification device which is mounted to the mounting section.

La présente invention concerne une machine de terrassement qui est pourvue : d'un cadre pour la machine de terrassement ; d'un moteur supporté à l'intérieur du compartiment moteur de la machine de terrassement par le cadre ; d'un dispositif d'épuration des gaz d'échappement qui comporte un filtre pour collecter des matières particulaires contenues dans le gaz d'échappement évacué du moteur ; d'un couvercle de compartiment pour définir le compartiment moteur ; d'un élément de support de couvercle de compartiment qui est un élément pour supporter le couvercle de compartiment et qui est prévu sur le cadre ; d'un capot de moteur qui est supporté par au moins l'élément de support de couvercle de compartiment et qui comporte une plaque supérieure, qui recouvre le compartiment moteur dans une position au-dessus du moteur, une ouverture, qui est prévue dans la plaque supérieure afin de permettre l'extraction vers le haut du dispositif d'épuration des gaz d'échappement à partir du compartiment moteur, et un élément de renfort, qui est disposé au bord périphérique de l'ouverture et qui supporte la charge du dispositif d'épuration des gaz d'échappement ; d'un élément de support de dispositif d'épuration des gaz d'échappement pour supporter le dispositif d'épuration des gaz d'échappement de manière telle le dispositif d'épuration des gaz d'échappement soit suspendu vers le bas à travers l'ouverture ; et d'un couvercle d'ouverture qui est monté de façon amovible sur le capot de moteur et ferme ou ouvre l'ouverture. L'élément de support de dispositif d'épuration des gaz d'échappement comporte une section de montage qui est montée sur le dispositif d'épuration des gaz d'échappement et une section de fixation qui est supportée par et fixée à l'élément de renfort. Lorsque la fixation de la section de fixation est libérée, l'élément de support de dispositif d'épuration des gaz d'échappement peut être retiré jusqu'à une position au-dessus de l'ouverture conjointement avec le dispositif d'épuration des gaz d'échappement qui est monté sur la section de montage.
