Abstract

PURPOSE: To enable adjusting of shovel width by means of an oil pump according to a digging width.
CONSTITUTION: A shovel 1 mounted on a shovel arm of a power shovel is divided into a central shovel body 2 consisting of a bottom plate and digging width adjusters 3 and 4 at opposite sides consisting of a part of the bottom plate and a side plate. The first and second cylinders 6 and 24 individually equipped with a pair of pistons at both sides are installed at an inner surface of an upper and a lower part of said shovel body 2, and pistons 9, 10, 28, 29 of the oil cylinders 6 and 24, respectively, are coupled to an upper and a lower part of the side plate of the digging width adjuster 3 to enable adjustment of the digging width by feeding and discharging a hydraulic oil to a hydraulic cylinder. Thus, this eliminates the need for exchanging of the shovel according to the changes in the digging width.
