Working Machine

Abstract

A hydraulic excavator includes: a revolving upperstructure; a working device attached to the revolving upperstructure; an operator's cab which has a rear window and is disposed in a front position of the revolving upperstructure; and an engine room which is disposed in a rear position adjacent to the operator's cab and has a ceiling part made of a cover member. A part of the cover member located near the operator's cab is made of an inclined surface part having a shape whose height gradually increases toward the rear of a vehicle body with the vicinity of a lower end part of the rear window as a start point during a predetermined distance immediately after the operator's cab. The height of the start point of the inclined surface part may be set equal to or lower than the height of the lower end part of the rear window.

1 . A working machine comprising: a revolving upperstructure; a working device which is attached to the revolving upperstructure; an operator's cab which has a rear window and which is disposed in a front position of the revolving upperstructure; and an engine room which is disposed in a rear position adjacent to the operator's cab and which has a ceiling part made of a cover member; wherein:
 a part of the cover member located near the operator's cab is made of a face shape part having a shape whose height gradually increases toward the rear of a vehicle body with the vicinity of a lower end part of the rear window as a start point during a predetermined distance immediately after the operator's cab.   
     
     
         2 . A working machine according to  claim 1 , wherein:
 the height of the start point of the face shape part is set to be equal to or lower than the height of the lower end part of the rear window.   
     
     
         3 . A working machine according to  claim 1 , wherein:
 the face shape part of the cover member is disposed to be out of a rotational locus which is virtually drawn by the lower end part of the rear window when the rear window is rotated on an upper end part of the rear window toward the engine room.   
     
     
         4 . A working machine according to  claim 1 , wherein:
 the cover member of the engine room includes the face shape part, and an engine cover which is provided so horizontally as to be consecutive to the face shape part and which can be opened/closed; and   a handle which is attached to the engine cover and which is used when the engine cover is opened/closed is provided and disposed in the vicinity of an end part of the engine cover located near the face shape part.   
     
     
         5 . A working machine according to  claim 1 , wherein:
 a heat exchanger is disposed in a place in the engine room just under the face shape part of the cover member.
