Abstract: A fastening post for a traffic-rated utility vault cover comprising an oblong mass with a tapped hole on its upper surface and a drainage port in its side surface where the upper end of tapped hole intersects with the lower end of drainage port in the interior of the oblong mass to form a smooth junction between these members. This design allows all debris falling into the tapped hole to slide down into the drainage port where it continues to fall and exit the oblong mass through the lower end of the drainage port. Fastening post has overall width that is at least three times that of the bolts or fasteners used to fasten down the hatch to the frame of the utility vault cover. Together with a specifically designed utility vault cover, fastening post provides a vibration-free reversible connection between the hatch and the frame of utility vault cover.

Abstract: A hinge member providing a pivotal connection between a utility vault hatch and a utility vault frame that provides an adjustable torsion lift system with one-way bias. Hinge member comprises a fixed end socket, a floating end socket, a torsion bar member, and a collar member. Fixed end socket and floating end socket are rigid cylindrical members with a cylindrical exterior surface and a polygonal socket at in its interior. Torsion bar member is an oblong rod or bar with an external polygonal shape that fits the polygonal sockets on the fixed end socket and the floating end socket. Collar member is a rigid cylindrical member with a cylindrical exterior surface and a hollow cylindrical center. Collar member has a T-slot void cut into its cylindrical exterior surface. Floating end socket further comprises an ear member, which is inserted into the T-slot of collar member.
