A construction machine comprises a lower traveling body, an upper turning body, and a turning frame that constitutes the bottom portion of the upper turning body. The turning frame comprises a bottom plate, a first vertical plate and a second vertical plate, and a coupling member that divides the space between the first vertical plate and the second vertical plate. The coupling member includes a top plate and a front and rear pair of a front side plate and a rear side plate that extend downward from both ends of the top plate in the front to rear direction, and forms a box shape structure with the first vertical plate and the second vertical plate. The box shape structure has a first opening formed in the first vertical plate, a second opening formed in the second vertical plate, and a front engine support part formed in the top plate.

An objective of the present invention is to provide a counterweight of a power shovel interchangeable with that of a superordinate model without affecting a rear end radius of the shovel at the time of rotation. In the power shovelin which the counterweight is formed at the rear part of a vehicle body frameextended from a front end to a rear end of a lower part of a rotation upper body, and an engineis mounted on the rear part of the vehicle body frame, an additional weightis placed in a space between the rear part of the vehicle body frameand the engine
