<p><P>PROBLEM TO BE SOLVED: To improve work efficiency by optionally selecting whether to use a closing side stopper according to work contents of inspection work, maintenance work, or the like and a work environment. <P>SOLUTION: This construction machine comprises a wire stopper 42 for holding a tank cover 32 in an open position, and a bar stopper 43 for regulating the closing of the tank cover 32 held in an open state. In the case of simple inspection work, the tank cover 32 can thereby be easily opened and closed omitting the operation of the bar stopper 43. In the case of work requiring a time and labor or outdoor work in the wind, the tank cover 32 is prevented from closing inadvertently by operating the bar stopper 43. Work efficiency can thereby be improved by optionally selecting whether to use the bar stopper 43 according to the work contents and the work environment. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
