ABSTRACT:
A novel multiple pier section and installation assembly includes a plurality of modular pier sections, a dolly for transporting, installing and removing the individual pier sections, and a dolly locator. The pier sections have a hinged pier section interconnection system which utilizes a dual pin/slot arrangement that resists both lateral and longitudinal as well as verticla movement of the installed pier. Adjustable pier legs which can be raised or lowered from atop the pier to accommodate variations in water depth are mounted to one end of each modular pier section. The dolly includes a chassis and a pivotally mounted pier section support unit, a dolly hold down system and a pier section hold down system. The dolly and dolly locator cooperate to assure proper alignment and positioning of the dolly during installation and removal of the pier sections.
