Personnel can supplement urea water by tilting container B X from container BX to urea water tank 20.In this way, staff can be preceding
Adjunctive program is carried out on the gorge CR1 of side.Lifting gear 50 is installed on the position of more posteriorly than urea water tank cover 41 side (sides-X)
It sets, therefore the obstacle of adjunctive program will not be become.
As described above, the excavator involved by the embodiments of the present invention, in the right side (sides+Y of upper rotation 2
Face), more posteriorly than urea water tank 20 position of side (sides-X) is provided with lifting gear 50.Therefore, in front side gorge CR1
On, lifting gear 50 (such as guard rail 52) will not be done with container B X when staff supplements urea water to urea water tank 20
It relates to.Thus, workability when supplementing urea water to urea water tank 20 will not be damaged.
Also, lifting gear 50 is installed in the right side of upper rotation 2 (sides+Y).It is therefore not necessary to which top is returned
The right front of swivel 2 is used as lifting gear.Thus, the height of the upper surface of tool box cover 42 is also not restricted to be adapted as
The height of the stage portion of the ladder of lifting gear.As a result, space 21 can be amplified as needed.
More than, the preferred embodiment of the utility model is described in detail, but the utility model is not restricted to
The above embodiments.Therefore, in the above-described embodiment, do not depart from the scope of the utility model and various improvement can be subject to.
For example, in above-described embodiment, urea water tank 20 is configured to supply opening 22 towards front side (sides+X).However, this practicality
It is novel to be not limited to the structure.Urea water tank 20 for example can be configured to supply opening 22 towards right side (sides+Y).
