Claims

[Scope of utility model registration request]

(1) An upper rotating body that is rotatably provided with respect to the lower traveling body, a working device that is installed on the upper rotating body so that it can be raised and raised, and a rotating upper structure that is arranged to balance the working device in the longitudinal direction. A counterweight provided at the rear end position,
In the construction machine, which comprises an engine installed in a building cover of the upper revolving structure and an air cleaner that supplies clean air to the engine, the counterweight has an air introduction hole at one side in the left and right direction. The air introduction hole is connected to the intake port of the air cleaner, and the counterweight is removed in order to prevent lateral asymmetry acting on the upper revolving structure by forming the air introduction hole. A construction machine characterized in that the entire upper revolving body is moved to the other side in the left and right direction to a balanced position.

(2) The construction machine according to claim (1), wherein the air introduction hole is opened on the upper surface side of the counterweight.

(3) A driver's cab provided in the upper revolving body is installed on the side where the air introduction hole is bored, and the operator's cab is expanded by the amount by which the upper revolving body is moved to the other side in the left and right direction. A construction machine according to claim (1) of claim (1) for utility model registration.
