Abstract
A hydraulic clamshell bucket apparatus employs a frame that includes an upper lifting member that enables the frame to be lifted with a crane or other lifting device. First and second hydraulically powered jaws and jaw pivots are provided on the frame. First and second hydraulic cylinders pivot on the frame above the jaw pivots, each cylinder connected to the frame at an upper cylinder pivot. Each cylinder pivotally attaches to a jaw at a lower cylinder pivot. Each jaw has a concave surface. First and second digging implements are attached to the jaws. Each digging implement has a concave portion. Each digging implement is wider than the jaw to which it is attached so that each implement extends laterally away from the jaw to which it is attached. A pair of side panels is attached to each digging implement at positions spaced away from the jaws.
