ABSTRACT:
A light pole erector and remover (10) for pedestal mounted light poles (74) that is comprised of three major elements: a transportation dolly (20), a pedestal attaching and lifting mechanism (22), and a pole tilting mechanism (24). The dolly (20) has fixed and steerable wheels attached to a tongue (34). The mechanism (22) is hinged to the dolly (20) and has a pair of base support arms (52) that embrace a concrete pedestal (56). Each arm (52) has a ratchet buckle tie-down (58) used for encircling the pedestal (56) and securing the mechanism (24) to the pedestal (56). The mechanism (24) is pivotally affixed to the mechanism (22) and includes a pair of ratchet buckle tie-downs (58) that encircle and secure the pole (74) to the invention (10). The pole (74) is horizontally positioned on the tilting mechanism (24), tied down and rotated to a vertical position over the concrete pedestal (56) and then lowered for attachment to the pedestal (56). The invention (10) also permits the pole (74) to be removed for repair or replacement.
