Power shovel

Provide is a construction machine allowing an air cleaner to be located entirely low while securing dust-discharge function thereof, with no risk of adverse effects such as diffusion of dusts and complication in structure. The construction machine includes an engine and an air cleaner connected to an intake-side portion of the engine to filter intake air. The air cleaner includes an air-cleaner main body which filters the intake air and an evacuator which discharges dusts separated from the intake air and protrudes downward beyond the air-cleaner main body. The air-cleaner main body is placed on an air-cleaner placement surface, the evacuator protruding downward beyond the air-cleaner placement surface at a position deviated outward from the air-cleaner placement surface.

Construction machine

Provided is a construction machine including: an upper slewing body including an upper frame; an engine room on the rear portion of the upper frame; a cabin on the front portion on the right or left side of the upper frame; a plurality of tanks including a fuel tank and a hydraulic tank installed on the upper frame; an air cleaner; a center foothold on the intermediate portion in the width direction of the upper frame and forward of the engine room; and a climbing step at the opposite side to the cabin. A first tank of the plurality of tanks is placed on a portion on the right or left side of the upper frame, and a second tank is arranged on a portion between the cabin and the engine room on the opposite side to the first tank. The air cleaner is superposed on the second tank.

Counterweight for construction machine

A construction machine that permits an exhaust gas after-treatment device to be disposed while avoiding an increase of height and hence avoiding narrowing of an operator's visual field. A guard panel is disposed substantially in parallel with a base frame. The guard panel includes a top plate, the top plate including an opening formed at a portion thereof corresponding to an engine, and a bonnet formed so as to project upwards from the top plate and cover the opening. A first treatment section is disposed lower than the top plate and a second treatment section includes at least a portion positioned higher than the top plate through the opening and lower than the bonnet.

A construction machine that permits an exhaust gas after-treatment device to be disposed while suppressing an increase of height. An upper surface of a hydraulic pump is positioned lower than an upper surface of an engine, a tank device having at least one of a working oil tank and a fuel tank is provided at a rear portion thereof with a small height portion which has an upper surface of a height almost equal to or smaller than the height of the upper surface of the hydraulic tank, and an exhaust gas after-treatment device is disposed at a position above both the small height portion and the hydraulic pump.
