Abstract
A water vehicle lift includes a winch which is operable to extend and retract an elongated flexible cable to lower and raise a platform on which a small water vehicle may rest. The winch is preferably mounted on a piling with the platform moving up and down adjacent the piling. On the face of the platform immediately adjacent the piling, a wheel is provided which rolls on the surface of the piling to maintain the platform slightly spaced away from the piling.
Claims16
In combination with a vertically disposed support structure having a top portion and an outer surface, a water vehicle lift comprising:
- a) a winch mounted on the top portion of the support structure and being operable to extend and retract a flexible cable;
- b) said cable having a proximal end attached to said winch and a distal end fastened to a lift platform;
- c) said lift platform having a horizontally disposed support surface for supporting a water vehicle;
- d) an elongated first guide means fixed to said vertically disposed support structure above a surface of the water, second guide means fixed to said lift platform and engaging said vertically disposed support structure and slidable means attached to the lift platform for engaging the first guide means whereby movements of said cable guidingly moves said lift platform vertically adjacent said vertically disposed support structure.
In combination with a vertically disposed support piling having a bottom portion mounted in a bed beneath a body of water and a top portion above the water supporting a winch operable to extend and retract a flexible cable attached to a water vehicle lift, the improvement in the water vehicle lift comprising:
- (a) the flexible cable attached to the winch at a proximal end and to a lift platform at a distal end, the lift platform having a horizontal support surface for supporting a water vehicle,
- (b) a tubular guide member spaced from the support piling and mounted parallel to the piling by an elongated bracket, the flexible cable passing through the tubular guide member,
- (c) the lift platform integral with a pipe moveable within the tubular guide member juxtaposed to a high strength polmer attached to an inside wall of the tubular guide member and
- (d) a roller axially mounted on an end of the lift platform adjacent the support piling so that movement of the lift platform by the winch permits the roller to guide the lift platform with respect to an exterior surface of the support piling.
