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.

Description

TECHNICAL FIELD[0001]The present invention relates to a working machine such as a hydraulic excavator, in which an operator's cab having a rear window and an engine room adjacent to the operator's cab are disposed on a revolving upperstructure.BACKGROUND ART[0002]Because of working environment, etc., a working machine provided with a revolving upperstructure, such as a hydraulic excavator, is restricted by the width of the revolving upperstructure and the size of rearward protrusion of a counter weight disposed at the rear of the revolving upperstructure in order to prevent the slewing radius from coming out of the vehicle width of a traveling base if possible. Accordingly, for example, in the case where a ventilation area of a heat exchanger received in an engine room disposed on the revolving upperstructure is intended to be set large, the height of the engine room needs to be set large. Particularly, it has become recently necessary to install an exhaust gas disposal device or a ...

AI Technical Summary

Benefits of technology

The invention is about a vehicle that has a space between the rear window of the operator's cab and the engine room ceiling, which makes the operator's seat more comfortable and allows for better handling. This space also allows the operator to have a wider rearward visual field, improving performance while performing work while looking at the rear of the vehicle.

Problems solved by technology

Thus, the height of the engine room tends to increase as the number of devices installed in the engine room increases or the size of each device increases.
