Abstract
Abstract The disclosure is of a combination cylindrical pipe handle and hoist mounting device for use in lifting and handling joints of large diameter pipe. With the hoist mounting device inserted into the cylindrical pipe handle that may be of various diameters or which may be of one diameter for use as an inseparable item from the same hoist mounting device, applicable hoisting equipment may be applied to the mounting device, permitting the cylindrical pipe handle to be firmly inserted into an open end of a large diameter pipe, longitudinally engaging the inside wall of a pipe section and the cylindrical pipe handle with close tolerance, thus permitting vertical lifting and horizontal handling of the pipe.
