Patent ID: 8340874

Claim:
A construction equipment including a hydraulic pump driven by an engine, a lower driving structure, an upper swing structure swingably mounted on the lower driving structure, a working device mounted on the upper swing structure and having a boom, an arm and a bucket each respectively driven by a hydraulic cylinder, the construction equipment comprising: a rear view camera installed on a predetermined rear position on the upper swing structure and photographing rearward and lateral sides of the construction equipment in real time; a monitor provided in a cabin mounted on the upper swing structure to display an image output from the rear view camera; a driving detecting unit for detecting driving of the hydraulic pump to output a detected signal, the driving detecting unit comprising a sensor for detecting when pressure of working oil of the hydraulic pump is more than a set reference pressure; a control unit for displaying the image output from the rear view camera on the monitor when pressure of the working oil of the hydraulic pump is more than a the set reference pressure; and an image turning-off means for turning off the image displayed on the monitor when a working condition is changed by a driver; wherein the driving detecting unit of the hydraulic pump includes a second sensor for detecting a current value applied to an electronic proportional control valve which controls a pump regulator adjusting an inclined angle of a swash plate so as to control a discharge amount of the hydraulic pump, and the second sensor transmits an electric signal corresponding to the current value to the control unit.
