A Look At How
Boat Lifts Work And The Different Types
By: Ignacio Silverstone iSnare Expert Author
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.
