ABSTRACT:
A flotation element for placement under a floating dock provides an elongate rectilinear flotation block carrying two spaced upper surface beams on its upper surface, and two spaced lower surface beams on its lower surface. The upper surface beams extend from one end of the flotation block to project beyond the second end, where they define holes to interconnect a tension member, and the lower surface beams extend between the ends of the flotation block. For use, a pulling support carrying a pulling device having an elongate flexible tensile element is positioned on or adjacent to the dock. The flotation element is placed on a first dock side, the pulling device is supported to move the tensile element toward the second dock side, and the tensile element is passed beneath the dock and attached to the projecting ends of the upper surface beams. The flotation element is angulated downwardly and toward the pulling device and the tensile element is moved toward the pulling device to move the flotation element beneath the dock. The pulling device may be supported spacedly distant from the dock to allow direct pulling by the tensile element or on the dock to allow indirect pulling over a pulley supported spacedly outwardly from the second dock side.
