Abstract
The construction machine according to the invention is distinguished by the fact that an air-processing apparatus () is arranged outside the cab () on the machine frame (), wherein a device () for feeding processed and/or fresh air into the cab and used air from the cab is provided, said device having a feed air duct for processed air for the cab and a discharge air duct for used air from the cab. The feed air duct of the air-processing apparatus () is connected to the outlet (C) of the air-processing apparatus () and the discharge air duct is connected to the inlet (B) of the air-processing apparatus. In a construction machine whose control station is rotatably arranged on the machine frame, the arrangement with the air-processing apparatus outside the cab has the decisive advantage that it is not necessary to run hoses and/or lines between the rotatable cab and the machine frame. A preferred embodiment of the construction machine provides for the feed and discharge air duct of the air-processing apparatus () to have an outer section () which is formed by a component connected to the machine frame in a rotationally fixed manner and an inner section () which is formed by a component connected to the cab in a rotationally fixed manner, wherein the outer section encloses the inner section. Thus concentric air conduction via the swivel joint of the control station is possible.
