Abstract
A clamshell cage assembly is provided for use in conjunction with a portable personnel lift. The personnel lift may be either a jib boom lift or a lift having a multi-sectional telescoping mast. The clamshell cage assembly has an upper and mid-level safety rail, portions of which pivot to a raised position which facilitates easy entry into the cage wherein the user does not have to stoop or use either hand to hold the cage open. The movable section of safety rail is then pulled downwardly by the user once he has entered the cage.
