Claims (1)

[Scope of Claim for Utility Model Registration] (1) An upper rotating body is connected to the upper part of the lower traveling body so that it can turn within the width of the vehicle, and a lower boom is attached to the front part of the upper rotating body, and an offset A parallel link type gutter excavator is installed in which the upper boom can be swung laterally by a cylinder, and a bucket attached to the tip of the parallel link type gutter excavator is used in a direction parallel to the longitudinal direction of the upper revolving structure. When the above-mentioned gutter excavating device is operated to its maximum swing, the bucket at the tip of the gutter excavating device is moved to the outside of the vehicle width range, approximately at the mouth width of the bucket. A swing shovel within the width of a vehicle, characterized in that it is configured to allow further offset movement. (2) An upper rotating body is connected to the upper part of the lower traveling body so that it can turn within the vehicle width, a lower boom is attached to the front part of the upper rotating body, and an offset cylinder is used to move the upper boom laterally. Equipped with a swingable parallel link type gutter excavator, and a bucket attached to the tip of the parallel link gutter excavator, it is possible to excavate approximately within the width of the vehicle in a direction parallel to the longitudinal direction of the upper revolving structure. In the above-mentioned vehicle width swinging excavator, there is provided a detection means capable of detecting whether the bucket at the tip of the side ditch excavating device is within the vehicle width range or outside the vehicle width range when the ditch excavating device is being operated in a swinging manner. A shovel that swings within the width of the vehicle. (3) An upper rotating body is connected to the upper part of the lower traveling body so that it can turn within the vehicle width, a lower boom is attached to the front part of the upper rotating body, and an offset cylinder is used to move the upper boom laterally. Equipped with a swingable parallel link type gutter excavator, and a bucket attached to the tip of the parallel link gutter excavator, it is possible to excavate approximately within the width of the vehicle in a direction parallel to the longitudinal direction of the upper revolving structure. In addition, in the in-vehicle width swinging excavator which can offset the bucket cart to the outside of the vehicle width range, when the ditch excavating device is oscillated, the bucket cart attached to the tip of the ditch excavating device swings. A shovel that swings within the width of a vehicle, characterized in that a restricting means is provided so that the range is within the width of the vehicle.
