摘要:
A boat lift has a transverse flotation tank that joins a first flotation tank construct and a second flotation tank construct. The transverse flotation tank has one or more pumps that evacuate water from the first flotation tank construct, the second flotation tank construct and the transverse flotation tank and create flotation of the boat lift. Modular boat lifts may be constructed according to the invention that have substantial size but are transportable by truck for construction on site.
摘要:
A floating boat lift having flotation tanks positioned under sides of a frame of the boat lift and a transverse flotation tank that communicates with the flotation tanks. Water flow is regulated so that tanks fill from near the center of the boat lift. Water is accepted into or pumped from the flotation tanks, allowing the frame of the boat lift to fall or rise relative to the surface of the water.
摘要:
A boat lift has flotation tanks positioned under sides of a frame of the boat lift. Water flow is regulated so that tanks fill relatively evenly to maintain a surface of the boat lift that is generally horizontal at all times. Hingeable connection of the boat lift to a bulkhead, along with lateral stabilization, participates in maintaining a generally horizontal attitude for the boat lift. Water is expelled from the plurality of flotation tanks by pumping water from the flotation tanks, allowing the frame of the boat lift to rise. One or more catwalks along the sides of the boat lift and connected to the bulkhead are also floating, but at a level that is independent of the boat lift frame.

This invention relates to an integrated heavy lift and logistics vessel (100) for receiving another vessel (105). Further the integrated heavy lift and logistics vessel (100) is able to provide logistical support to the other vessel in remote locations. More particularly, this invention relates to an integrated heavy lift and logistics vessel that is designed to carry out heavy lifting and logistic supply functions in a stable manner. The integrated heavy lift and logistics vessel is also equipped with safe refuge quarters, helipad(s), various forms of storage, and areas for storage.

An air direction device is submerged under a dry dock. The device imitates the orientation of the dry dock and is in communication with an air source, which pipes air under the device. The air travels to the most elevated portion of the device, which in turn directs the air into a depressed tank to correct dry dock imbalance.
摘要:
A free-floating, compact, self-stabilizing, self-monitoring, remote-controlled, shallow-water, solar, high-speed, air displacement watercraft lift constructed of polyethylene tanks, and non-metallic structure. This device provides vertical lifting by inflating 4 or more air tanks at once using a blower for each tank, pushing water out an exit hole on the bottom of each tank. Each tank has an electric valve for filling and another for exhausting air. Pairs of tanks are pivotally connected along the centerline, and pairs of tanks are connected with a union tube inside the axles. A monitoring system fills the air tanks if air leaks. The width of the lift is adjusted by adjusting the center bunk height, or by adding a spacer.

This invention relates to a ready system for providing floating dock deflection management systems increasing operations efficiency and providing accurate, safe control to eliminate man-made accidents. This invention also relates to a ready system for providing floating dock deflection management systems providing information to safely operate at least one dry dock without over-stressing the metallurgy of the dry dock.

A lift is placeable in a waterbody for a watercraft having a water intake port and a water drawing device for drawing water through the water intake port. The lift includes a tank. The tank has an interior and an exterior, with the interior including a chamber. The tank also has an upper surface configured for receiving the watercraft, and a water inflow port and a selectively actuable valve for permitting water to flow into the chamber. A water outflow port is provided which is configured to be matable with the water intake port. The water intake port of the watercraft can be mated with the water outflow port of the tank to permit the water drawing device of the watercraft to draw water out of the tank.
摘要:
A floating boat lift for lifting and supporting a boat above the surface of a body of water. The device includes a lower pontoon base and two elongated upper pontoons positioned above the lower pontoon base and held spaced apart and generally parallel one to another by a rigid frame connected therebetween. The upper pontoons are laterally restrained and are controlledly movable vertically with respect to the lower pontoon base by a vertical actuator arrangement. The upper pontoons may be filled or emptied of water. When empty, the actuator arrangement extends in length so as to lift the upper pontoons from the water. A boat placed atop the frame is also lifted and held above the water as the upper pontoons are drained. When the upper pontoons are filled with water, the actuator arrangement compresses in length and the lower pontoon base submerges until the lower portions of the upper pontoons become submerged, at which point the boat may be floated onto or removed from the submerged frame. The device is fully self-buoyant during all aspects of use.
摘要:
A boat lift and leveler are provided in which the boat lift consists of a cradle supported by at least two pontoons laterally disposed beneath and fixed to the cradle. A leveler for the lift includes a pair of pneumatic duct systems. One of the systems connects to air vents on the starboard side pontoons and the other system connects to air vents on the port side pontoons. Each system includes an intake path, an exhaust path and a valve in each path. The intake path is connected to a source of air under pressure and the exhaust path extends to the atmosphere. An enclosure fixed to the lift lists to starboard or port with the lift. A V-shaped track rests in the enclosure. The track has a starboard arm which rotates below horizontal at a predetermined degree of starboard list of the enclosure and a port arm which rotates below horizontal at a predetermined degree of port list of the enclosure. One mechanism automatically closes the intake path valve to the pontoons on the starboard side of the lift when the port arm falls below horizontal during the lifting process. A similar mechanism controls the port side pontoons in response to the starboard arm. Another mechanism automatically closes the exhaust path valve to the pontoons on the starboard side of the lift when the starboard arm falls below horizontal during the lowering process. A similar mechanism controls the port side pontoons in response to the port arm.
