Abstract

A construction machine comprises a lower traveling body and an upper revolving body rotatably attached to the lower traveling body via a revolving mechanism 2, wherein a rear surveillance camera is arranged on a back surface side of the upper revolving body between a counter weight of the upper revolving body and a swing circle of the revolving mechanism, and right and left crawler end portions of the lower traveling body 1 can be simultaneously visually checked by means of the rear surveillance camera.

Claims

1. A construction machine comprising:

a lower traveling body (1);

an upper revolving body (3) that is rotatably attached to the lower traveling body (1);

a traveling operation means (26) including travelling levers for moving said lower travelling body (1) forward or backward in such a way that when the travelling levers are pressed forward, the lower travelling body travels forward, and when the travelling levers are pulled backward, the lower travelling body travels backward;

a monitor screen (39) having first and second display modes; and

,

a rear surveillance camera (38) arranged on said upper revolving body (3),

wherein an image from said rear surveillance camera (38) is only displayed on said monitor screen (39) in said first display mode by operating said traveling operation means(26),

wherein a vehicle body condition is displayed on said monitor screen in said second display mode when said travelling operation means (26) is not operated.

2. A construction machine comprising

a lower travelling body (1);

an upper revolving body (3) that is rotatably attached to the lower travelling body (1);

a travelling operation means (26) including travelling levers for moving said lower travelling body (1) forward or backward in such a way that when the travelling levers are pressed forward, the lower travelling body travels forward, and when the travelling levers are pulled backward, the lower travelling body travels backward;

a monitor screen (39); and

a rear surveillance camera (38) arranged on said upper revolving body (3),

wherein a switch (48) for allowing the monitor screen (39) to be in a state of displaying either an image from said rear surveillance camera (38) or a vehicle body condition is provided in said travelling operation means (26).
