A Look At How Boat Lifts Work And The Different Types
Boat lifts are used to lift the boat and store the boat above the water surface. Boat lifts are generally of two types. They are i) Hydro hoist model and ii) the Air-Dock model. Boat lifts are manufactured keeping in mind the different sizes of the boats.
Boat lifts work on the principle of lifts and hoists. In Hydro hoist type model there are float tanks that have a drain fitting at the bottom which is always open to the water. The boats are lifted with the help of hoists that are driven by heavy motors. The Hydro-Hoist boat lifts are of several types such as Boat Floater, Econo Lift and others. In the case of Air Dock the pressure of air is required to uplift the boat to a certain height above the water surface. With Air Dock type boat lifts there is a water tank which is filled and evacuated with the air pressure. Here the air is pumped in from the atmosphere to force the water out of the water tanks thus lifting the hoist. To lower down the hoists, one should vent the air pressure to allow water to fill the again tank.
Generally a motor with a blower is attached which is about the size of a vacuum...
