摘要： An information display unit 47 is provided inside a cab of a hydraulic excavator 1 and has a display portion 471 capable of displaying plural kinds of information including body information and maintenance information. A screen image displayed on the display portion 471 comprises one main screen and a plurality of sub-screens. The main screen displays information regarding one of a plurality of information categories in detail and the plurality of sub-screens respectively correspond to the plurality of information categories. The sub-screens corresponding to the information categories other than the information category, for which information is displayed on the main screen in detail, display the corresponding information categories in the simplified form. The information category displayed on the main screen can be selected and changed with key manipulation made on an operating portion 470. As a result, plural kinds of information can be displayed in a combined and selective manner, and an operator is able to confirm the information with higher efficiency.

摘要： To provide a cold/warm air outlet assembly for construction a machine, said assembly being capable of fully meeting desires on the comfort of a working environment of an operator under air conditioning and use of air conditioning for a multiplicity of purposes, an upper outlet tube 2 and lower outlet tube 3 are formed into substantially tubular shapes having conical circumferential walls with walls, through which air out lets 20.30 are formed, being included as tilted walls. The upper outlet tube 2 is resiliently fitted and connected to the lower outlet tube 3, and the lower outlet tube 3 is resiliently fitted and connected to a vertical part 11a of an air conditioner duct 11. The upper and lower outlet tubes 2,3 are, therefore, turnable in horizontal direction at their connected parts. By operating air-direction control knobs 24,34 arranged in the air outlets 20,30 directed toward desired turned positions, the vertical directions of the internal fins 21 1 -21 3 ,31 1 -31 3 can be adjusted to cause cold/warm air to blow out in the desired directions, respectively.

摘要： An information display device (47) has a display unit (471) which is provided in an operator cab of a hydraulic shovel (1) and capable of displaying information including vehicle body information and maintenance information. On the screen of the display unit (471), one main area and sub-areas are displayed. An information set of one of a plurality of information categories is displayed in the main area in detail, and information sets of the other information categories are displayed in the sub-areas. The information categories of the information sets displayed in the sub-areas are simply displayed in the main area. One of the information categories displayed in the main area can be selected and switched by the key operation of an operation unit (470). A plurality of kinds of information can be displayed in a composite and selective manner, and the efficiency of understanding information by an operator can be improved thereby.
