ABSTRACT:
The disclosed invention relates to a single hoist line operated clamshell bucket apparatus and method of use. The bucket apparatus is loaded in the usual manner at a first location for transporting bulk material to a second location where it is discharged. The bucket is discharged by sensing the presence of a preselected radio command signal that is controlled by the crane operator. The sensed radio signal operates a shut-off valve in a hydraulic controlled bucket latching system to release hydraulic fluid to permit discharge of the clamshell bucket.
