<P>PROBLEM TO BE SOLVED: To provide construction equipment which facilitates watering work of an aqueous urea solution, maintenance work of an aqueous urea solution tank, etc., by setting the aqueous urea solution tank at an adequate location. <P>SOLUTION: The aqueous urea solution tank 32 in which the aqueous urea solution is stored, is arranged on a truck frame 6 of a lower traveling body 2, by using a front space of a support cylinder body 11. Thus the aqueous urea solution tank 32 can be arranged on the lower traveling body 2, and therefore the aqueous urea solution in the aqueous urea solution tank 32 can be injected from an aqueous urea solution injection device 30 into an exhaust pipe 20B of an engine 20, which enables cleaning of nitrogen oxides discharged from the engine 20 by a urea selective reduction catalyst 29. Further the aqueous urea solution tank 32 is mounted on the truck frame 6 of the lower traveling body 2, i.e. arranged at a low location of the construction equipment, and therefore the aqueous urea solution can be easily replenished from the ground. <P>COPYRIGHT: (C)2008,JPO&INPIT |
