ABSTRACT:
An excavator mounted with tanks having side doors. Bend-formed side doors are mounted on outer sides of a hydraulic fluid tank and a fuel tank that are welded structures mounted on an upper frame of the excavator, have the same curved surfaces as an external shape of the equipment, so that no precise tank manufacturing work is required and welded portions of the tanks are prevented from being exposed to an outside.
