<p><P>PROBLEM TO BE SOLVED: To increase working efficiency by a large working space which is formed by largely opening the upper side of a tank even in a restricted working site. <P>SOLUTION: A tank cover 22 for covering the upper sides of a hydraulic tank 11 and a fuel tank 12 includes two members comprising a front cover part 23 which is positioned on the front side and opened to the front side about the front end 23C and a rear cover part 25 which is positioned on the rear side of the front cover part 23 and opened to the rear side about the rear end 25D. One front cover part 23 and one rear cover part 25 are formed small by dividing the tank cover 22 into two parts. Consequently, when an operation for supplying oil into the fuel tank 12 and a maintenance operation for the hydraulic tank 11 are performed at the restricted working site, the small cover parts 23, 25 can be easily fully opened with a light force without colliding with an obstacle therearound, and the work can be easily performed. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
