Abstract

PURPOSE: To simplify driving operation by enabling bucket to be pushed out horizontally only by the single operation of arm, the single operation of boom, and the operation of only one lever for operating the arm or the like.
CONSTITUTION: The base end of a bucket cylinder 10 is attached to a boom 3 in such a manner that the bucket cylinder 10 and the arm 5 form a approx. parallel link, and also the boom 3 and the arm 5 are connected providing a regulating cylinder 11. The regulating cylinder 11 and each rod push-out side oil chamber of the arm cylinder 6 are communicated with each other through a switch valve. And, the loading shovel is operated by mutually interlocking the arm cylinder 6 and the boom cylinder 4.
