Types of Trailer Jacks
Swivel Tongue Jacks
A swivel tongue jack is a trailer jack with a built-in mechanism that allows it to swivel out of the way when not in use. The swivel is achieved by a swivel assembly that is secured by a locking pin.
The increased ground clearance provided when the jack is swiveled to a horizontal position is the main benefit of this type of jack. It is less likely to accidentally hit the ground when going over bumps and ramps, which could damage the jack or trailer.
Swivel jacks can be bolted to a mounting plate or welded to a mounting tube. Some swivel assemblies use ball bearings, while others use two smooth tubes. The advantage of a two-tube swivel configuration is that the jack can be completely removed by simply removing the pin.
Drop-leg trailer jacks
Drop-leg trailer jacks allow the operator to quickly secure the legs in a lowered position to speed up the jacking process. Telescoping tubes and pins are used to simplify the lowering process.
The ability to quickly close the distance between the trailer jack and the ground is the main benefit of a drop-leg trailer jack. This downward motion reduces the amount of shaking required to lift the trailer tongue.
Some drop-leg trailer jacks include a spring-loaded foot that retracts on its own after the pin is pulled out. This feature allows the operator to retract the jack’s legs without having to bend over.
Electric trailer jacks
An electric trailer jack is a jack with an electric motor that retracts and extends the jack’s legs. They make operating the jack easier by reducing the amount of physical labor required. They work by plugging into the trailer’s electrical system to power the motor, and the user then uses a controller to move the trailer.
The main benefit of electric trailer jacks is that they eliminate the need for physical labor. Some jacks offer manual controls if the jack loses power. Electric jacks offer a great user experience, although they are more expensive than regular jacks.
Rigid-mount trailer jacks
Rigid-mount trailer jacks with foot plates are the simplest and most cost-effective of all trailer jacks. This type of jack is rare in nature, so it seems like everyone should have one on hand at all times.
These trailer jacks, whether they come with a side or top crank and are mounted on the side or have an A-frame mount, are the foundation for all other jacks.
A-frame jacks are located closer to the centerline of the trailer than side-mount trailer jacks. As a result, they have the particular advantage of very good load conditions. Side-mount trailer jacks create a torsional moment, and the further they are from the centerline of the trailer, the greater the torsional moment.
Boat Trailer Jacks Boat jacks are the jack of choice for those who spend a lot of time fishing or boating, as they can withstand the wear and stress that comes with frequent contact with water.
Boat jacks often come with wheels for increased portability and a more direct connection to the boat trailer. Boat jacks also include a heavy-duty pull pin that allows them to be swiveled on the mounting bracket and moved out of the way so that they are out of the way when transporting a vehicle.
These jacks have an anti-corrosion coating to prevent damage from rust and moisture.
Square Jacks Square Jacks are a heavy-duty trailer jack. Since its design allows it to be welded directly into the trailer frame, it provides greater holding power. Depending on the specific model, these heavy-duty models range in holding capacity from 8,000 pounds all the way up to 12,000 pounds, and lifting capacity from 7,000 pounds all the way up to 10,000 pounds.
Square Jacks are ideal for the rigorous demands of agricultural life and the construction business. These jacks come with either a side wind handle or a top wind handle, depending on the user's preference.
