Claim:
1. A construction machine comprising: a lower traveling body; an upper slewing body having an upper frame including a structural body including a plurality of beam members, the upper slewing body mounted on the lower traveling body so as to be slewable; a working attachment including a boom with a boom foot which is a base end thereof, the boom foot being attached to the upper slewing body; a first equipment unit placed on the structural body; and a second equipment unit other than the first equipment unit, the second equipment unit placed on the structural body, wherein the plurality of beam members provide a first placement surface on which the first equipment unit is placed, and a second placement surface on which the second equipment unit is placed, the second placement surface being lower than the first placement surface; the upper frame includes a center section having a pair of right and left vertical plates extending in a front-rear direction and a right side deck and a left side deck which are disposed on right and left sides of the center section, respectively; each of the vertical plates has a front end formed with a boom-foot-pin hole for attaching the boom foot to the vertical plate; one of the right and left side decks is a specific side deck including the second placement surface; the second equipment unit is placed on the second placement surface at a position where the second equipment unit is aligned with the boom-foot-pin hole in a right-left direction in a plan view thereof; and the specific side deck includes: a front auxiliary beam and a rear auxiliary beam each extending in parallel to the front lateral beam and the rear lateral beam in a placement space between the front lateral beam and the rear lateral beam, the second placement surface being formed in the placement space, each of the front auxiliary beam and the rear auxiliary beam having a smaller modulus of section than the first modulus of section and the second modulus of section; and a plurality of equipment-unit attachment members including a first support member disposed across the front lateral beam and the front auxiliary beam and a second support member disposed across the rear lateral beam and the rear auxiliary beam, thereby locating the second placement surface, in a front inter-boom region between the front lateral beam and the front auxiliary beam and a rear inter-boom region between the rear lateral beam and the rear auxiliary beam, at a position lower than respective upper surfaces of the front lateral beam and the rear lateral beam, each of the equipment-unit attachment members having the second placement surface.
