Abstract
A marine rail lift has a lift deck assembly configured to receive a watercraft thereupon and move between a raised position and a lowered position relative to a parent dock. A plurality of track rails connected to the side walls of a berth of the parent dock define a movement path of the lift deck assembly between the raised position and the lowered position. A plurality of retractable track pins engage the lift deck assembly to the track rails. A lift control system is operatively engaged with the lift deck assembly and configured to displace the lift deck assembly between the raised position and the lowered position. The lift control system manages the volume of air contained within one or more lift tanks of the lift deck assembly to control displacement of the lift deck assembly through buoyant force.
Claims11
A marine rail lift system comprising:
- a lift deck assembly configured to move between a raised position and a lowered position relative to a parent dock along a plurality of track rails;
- the track rails being connected within a berth of the parent dock, wherein the track rails define a movement path of the lift deck assembly between the raised position and the lowered position;
- a lift control system operatively engaged with the lift deck assembly, configured to displace the lift deck assembly between the raised position and the lowered position,
- wherein the lift deck assembly is configured to accept one or more watercraft thereupon;
- wherein the lift deck assembly is configured to convey the watercraft between the raised position and the lowered position;
- wherein the lift deck assembly is level with the parent dock when in the raised position;
- wherein the lift deck assembly is adjacent to a waterline beneath the parent dock when in the lowered position;
- and
- wherein lift deck assembly further comprises a plurality of retractable track pins configured to lock into the track rails.
