Abstract

The invention provides an engineering machine which can easily switch a radio and an air conditioner. The engineering machine comprises: a driving seat (18) arranged in a cab (4) on a rotation body (2); an operation device (15) arranged on the left-inclined front side of the driving seat (18) and used for operating a working device (3); a monitor (26) arranged on the right-inclined front side of the driving seat (18); a rotary switch (42) capable of observing the display of the monitor (26) and simultaneously operating the monitor and performing detailed settings of various state amounts; armrests (19) arranged on the driving seat (18); a switch box (17) with a plurality of switches and arranged on the outer side of the transversal direction of the operation device (15) and a structure provided with radio switches (38,39) and air conditioner switches (40,41) and arranged in an auxiliary are (17B) of the central part of the switch box (17).

Description

technical field [0001] The present invention relates to a construction machine such as a hydraulic excavator, wherein a driver's seat arranged in a cab has an armrest, and a radio switch and an air conditioner switch are provided in the cab. Background technique [0002] Figure 7 It is a front view showing the driver's seat part arranged inside the driver's cab of the conventional hydraulic excavator, Figure 8 It is a plan view showing the internal structure of a cab included in a conventional hydraulic excavator. [0003] such as these Figure 7 , 8 As shown, a construction machine such as a hydraulic excavator has: a running body forming a body body (not shown), a rotating body arranged on the running body; device. The base plate 50 forms the floor of the cab 70 disposed on the revolving body, and a base 51 is provided on the base plate 50 , and a support plate 52 is provided on the base 51 . On the pallet 52, consoles 53, 54 arranged in a pair in the left-right dire...

AI Technical Summary

Problems solved by technology

[0006] In the prior art described above, when operating the radio switch on the radio operating panel 59 or the air-conditioning switch on the air-conditioning operating panel 60, it is necessary to rotate the armrest mounted on the driver's seat 57 in the up and down direction as described above. kind of hard

[0007] In addition, when performing detailed setting of various state quantities while watching the screen of the monitor 61, when operating the detailed setting switch, the operator sitting on the driver's seat 57 must bend down and reach out to operate the monitor. The detailed setting switch on the lower side of 61 is also troublesome

In addition, when bending over to operate the detailed setting switch in this way, the operator's arm may come into contact with the operating lever of the operating device 55.

In this way, if the operator's arm comes into contact with the operating lever of the operating device 55, the operating device 55 is moved, which may cause a malfunction of the working device.
