A transport anchor for transporting a heavy part, which anchor is embedded in the heavy part, includes a sleeve having an inner thread for receiving a load bearing member. The sleeve has a first section with an exterior end face positioned flush with the exterior surface of the heavy part. The sleeve has a second section with a receiving member for an anchoring element of the heavy part. A first plug with an outer thread is threaded into the inner thread of the sleeve and is moveable along the inner thread. The first plug has a plug end face facing outwardly relative to the heavy part. The load bearing member can frictionally engage the plug end face of the first plug. The load bearing member has a base body with an outer thread for cooperation with the inner thread of the sleeve. The base body has a first end for insertion into the sleeve, whereby the first end has an end face with an axial recess or an axial projection providing at least one matching contact surface for cooperation with the at least one axial contact surface at the plug.
