ABSTRACT:
An apparatus for restraining and berthing a floating body or vessel on a water surface at a quay wall, comprises a driving subsystem, a movable member driven by the driving subsystem and forwardly and backwardly guided by guide members, and an elastic end piece such as a marine fender secured to the movable member and projecting away from the quay wall. The apparatus according to the invention can exactly move the end piece to a desired position for restraining the floating body and can utilize precompressive forces arising in the end piece, thereby accommodating tolerances or unintensional errors of the quay wall in construction and absorbing rocking energy of the floating body to hold it firmly in place in a harbor. The apparatus according to the invention retracts its elastic piece in a rest or inoperative position and extends it in an operative position to be in contact with a floating body such as a ship or boat to serve as a marine fender.
