Abstract
A loading arm that transfers flowing bulk material from a storage vessel and into a transport tank through a top hatch of the transport tank that is carried on a truck or rail car for transport includes an articulating arm having a plurality of connected hollow pipes. A hatch cone is connected to the arm and defines a top member, a bottom member, an inner shell connecting the top and bottom members and an outer shell extending between the top and bottom members. The outer shell of the hatch cone defines a truncated conical wall that is formed by a resiliently flexible section configured to deform resiliently upon engaging with the top hatch of the transport tank.
