DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a working machine on a slope or the like used for forming a slope on a high steep terrain portion or forming an earth anchor hole in the slope.

[0002]

2. Description of the Related Art A working machine on a slope where a slope is formed on a high steep terrain portion or various operations are performed, the present inventor installs two winches on the working machine body,

Things are considered.

[0003]

Since the tips of the conventional two winch support wires are fixed to fixed anchors at the left and right portions at a high position where the work is to be performed, the support of the winch for suspending the working machine body is provided. Since the wire always has a predetermined inclination angle, the load applied to the support wire is large, and the support wire that can withstand this load becomes thick, so that a large winch is required.

The present invention has been made in view of the above-mentioned conventional drawbacks,
The work machine main body can be suspended so that the wire of the winch to be suspended is positioned substantially in a straight line so that a large load is not applied to the wire, and the work machine can be smoothly moved in the left-right direction. The purpose of the present invention is to provide a working machine with a slope that can be used.

[0005] The above and other objects and novel features of the present invention will become more fully apparent when the following description is read with reference to the accompanying drawings. However, the drawings are for explanation only, and do not limit the technical scope of the present invention.
