A Look At How Boat Lifts Work And The Different Types
by: Ignacio Silverstone 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 cleaner motor. These motors blow the air out of the float tanks. Each
tank has a hole at opposite ends, where the hose is attached. These holes are
about 4 inches in diameter. An electric switch is used to turn on the blower and
a valve. To raise the boat lift the valve is opened and the blower motor turned
on. It can be left on until air bubbles are out of the 4 inch holes, this is the
maximum lift that can be obtained. Once the boat is lifted to the desired height
the valve is manually closed and all the air is retained in the tanks. When the
boat is to be launched the valve is opened and the captured air from the tank
escapes past the blower and the lift settles into the lake. Different new technologies are adopted regularly to enhance the working
principles of boat lifts. These new technologies are a floating drive-on dry
lifting system which makes existing technology obsolete. Fully portable,
changeable and modular boat lifts will work in shallow water or deep water,
fresh, tides or salt water, currents and even waves. These boat lifts have the
power to lift boats of different sizes, from small boats to large watercrafts.
Drive-on floating docks even replace those traditional lifts, boat hoists,
davits & trailers and provide a convenient dry-dock for stern drives, outboard
boats, inboard ski boats and jet boats of all sizes and shapes.
