Abstract:
A bucket assembly has a bucket which is openable and closable by means of fluid pressure applied to one and the other end of a cylinder. The assembly includes a joint which allows free rotation of the bucket through 360*, meanwhile providing that the fluid pressure may pass through the joint to one or the other side of the cylinder, irrespective of the rotative position of the bucket. A valving system is included for providing rapid opening of the bucket.
