Boat Lifts Under Boat Houses & Boat Ports
The Different Types Of Boat Hoist Lifts:
Commercial Boat Hoist Lifts raise a boat out of water for storage purposes. There are some boat owners who only use a hoist during the winter season, and there are some who raise their boats out of the water whenever they are not being used. The use of a hoist can assist in preventing damage such as rust; it also means that the boat will not drift away if it happens to become untethered. There are a range of different boat hoists available, they come in different sizes and they have different uses. There are small hoists which can be left on the boat in order to lift other objects. You will also find boat hoists on ships and on the docks, all of which are of different sizes. Here are some of the most common boat hoist lifts.
Air Lifts
An air lift is a type of boat hoist that provides a floatation cushion underneath its keel, and uses an air tank to raise a boat above water level. An air lift is made up of a series of tanks containing valves on the bottom. The operator causes the tanks to sink by allowing water into them to lower the house. When the boat is situated above the deluged lift, the air pump is turned on which fills the tanks up with air, pushing the water out of the valves so that the tanks float on the water; this is how the boat is raised. Once the boat is completely out of the water, the operator can turn the pump off and the air pressure will prevent the water from going into the tank.
Hydraulic Hoists
Hydraulic Boat Hoist Lifts are also referred to as elevator lifts. They use a metal frame which is attached to perpendicular guide posts. A hydraulic motor utilizes steel cables on pulleys to lift the hoist alongside the guide posts until the boat has been completely lifted out of the water.
There are some hydraulic boat hoists, such as those that are installed near docks that use four perpendicular guide posts, with one located at each corner of the hoist. Other hoists, like the ones installed alongside break walls, utilize two guide posts that have been fitted at an angle which raises the boat in the frame up close to the wall, and towards the shore until it is at an appropriate level for the passengers to debark.
Manual Hoists
Manual Boat Hoist Lifts are similar to a hydraulic hoist, but it relies on an operator to turn the crank instead of an electric motor. The crank is generally a large wheel made up of one or two handles; it is attached to an arrangement of pulleys with steel cables, providing the operator with the required mechanical assistance to lift the frame and the boat easily.
One of the main advantages of a manual hoist is that you can operate it even if there is no electricity to run the motors that are required for hydraulic hoists and air lifts.
