Abstract

An air conditioning apparatus for a hydraulic shovel with which a wide space in a cab can be secured and a placement operation of ducts for distributing wind to each important point in the cab is facilitated. For this purpose, in the air conditioning apparatus, an air-conditioning unit (21) is placed at a front portion of a right side in a cab (10). The air-conditioning unit (21) is mounted to a front portion of a right side wall surface (51) of the cab (10). The air-conditioning unit (21) is mounted to the right side wall surface (51) of the cab (10) to be capable of being taken in and out from an inside and an outside of the cab (10).

Description

technical field [0001] The invention relates to an air conditioner installed in the cab of a hydraulic excavator. Background technique [0002] A construction machine such as a hydraulic excavator has a cab, and the operator's seat is surrounded by a door for entering and exiting and a wall surface with windows, and a work machine operating device and a traveling operating device are installed inside the cab. In this cab, in recent years, air conditioners have been frequently installed in order to improve operability (window glass defrosters, etc.) and comfort (living) properties (air-conditioning, air conditioners). In the past, the air conditioner, for the purpose of ensuring a loose space in the cab and ensuring the visibility of the operator, for example, is installed between the operator and the rear wall of the cab (for example, refer to Japanese Patent Laying-Open No. 8-183323 No. 3 and Fig. 1), the rear wall of the cab or the floor surface under the operator's seat ...
