Embodiments of the invention are directed to a utility platform assembly a having a utility platform, an insulative liner, and a liner retention system. The insulative liner presents a complementary shape to, and is disposed in, the utility platform. The insulative liner is secured in place and protected from damage by the liner retention system. The liner retention system is disposed atop and through the liner near the top edge or edges of the insulative liner. The edge or edges of the insulative liner are therefore disposed between the liner retention system and the lip of the sidewall of the utility platform. The liner retention system generally comprises at least one retaining bar with an associated plurality of fastener receptors and fasteners.

Liner retention system for an aerial device

A jib assembly has a sheath, a jib arm disposed within the sheath, and at least two gripping components disposed on the inner surface of the sheath. The sheath is operable to engage the jib arm to secure the jib arm and prevent the jib arm from extending and retracting relative to the sheath by aligning the sheath to be substantially parallel with the jib arm. The sheath is operable to disengage the jib arm to allow at least a portion of the jib arm to extend and retract relative to the sheath by rotating the sheath away from substantially parallel with the jib arm.

Sliding lock mechanism for securing a jib assembly

An aerial work assembly including components having composite materials including a fabric-reinforced resin for providing electrically non-conductive assembly, by insulating and/or isolating conductive components.

Aerial work assembly using composite materials

An aerial work platform assembly is provided, comprising a platform shaft retaining assembly; a mounting bracket connected to the platform shaft retaining assembly; and a platform connected to the mounting bracket; wherein the platform shaft retaining assembly, mounting bracket, and platform are constructed from the same or differing composite materials comprising a fabric-reinforced resin. Optionally, the fabric-reinforced resin includes a preform fabric having a conformable three-dimensional weave, and the resin is a dielectric resin selected from either epoxy, epoxy vinyl ester, vinyl ester, polyester, or phenolic.
