Abstract

A device in excavating-machine buckets. The bucket (10) is pivotally mounted in a yoke part (12) and is operated to perform pivotal movements by means of a pair of piston-and-cylinder units (26) mounted in the bucket. In order to rotate the bucket the device comprises two tube blanks (28, 30) which are mounted in nesting relationship, the inner one of said tubes being secured to the yoke part (12) and to a lid (32). The device also comprises an attachment member (44), allowing the device and the bucket (10) to be mounted on a crane arm (46). Two piston-and-cylinder units (40) are mounted on said attachment member and secured to the lid (32) to operate the movements of the latter. Turning movement of the lid results in a turning movement of the inner tube blank (28) and of the yoke part (12) and the bucket (10). The outer tube blank (30) is secured to the attachment member (44). Wheels (36,38) are provided about the outer tube blank (30) to take breaking stress exerted on the tube blanks (28,30).
