Common Types of Trailer Jacks And Buying Guide

Trailer jacks are vital components of a trailer's towing system; they are primarily used to support the trailer tongue, facilitate coupling and uncoupling from the towing vehicle, and maintain stability when the trailer is parked.

Since different types of trailers vary in their operating environments, load-bearing requirements, and mounting methods, selecting the right trailer jack is crucial.

As a professional manufacturer—Chenwei Trailer Jack Factory—we offer a wide range of trailer jacks tailored to various trailer structures and operational needs.

I. Common Types of Trailer Jacks

1. A-Frame Trailer Jacks

A-frame jacks are typically mounted at the center of an A-frame coupler. They are suitable for utility trailers, cargo trailers, equipment trailers, and certain RVs.

These jacks feature a compact design and are easy to install. They effectively support the front tongue of the trailer and are among the most common types of trailer jacks available.

A-frame jacks are available in various specifications, lift ranges, and operating mechanisms to suit different load capacities and lifting requirements.

2. Swing-Away Trailer Jacks

Swing-away jacks feature a rotating bracket design.

The jack can be rotated into the working position during coupling, loading/unloading, or parking. Before towing, it can be rotated upward and stowed away, minimizing interference with ground clearance while the vehicle is in motion.

This design is particularly well-suited for boat trailers, utility trailers, and applications where the jack needs to be stowed frequently.

3. Direct-Weld Trailer Jacks

Direct-weld jacks are permanently attached to the trailer frame via welding, offering exceptional structural stability and a secure mount.

This mounting method is ideal for trailers that demand high stability and load-bearing capacity, such as livestock trailers, heavy equipment haulers, and other specialized trailers.

When selecting a weld-on jack, it is important to verify the mounting location, tube diameter, installation height, and the trailer's actual load requirements beforehand. 4. Bolt-On Trailer Jacks

Bolt-on trailer jacks are attached to the trailer frame using mounting brackets and bolts.

Compared to weld-on models, bolt-on jacks are easier to install and remove, making them ideal for trailers that may require jack replacement, repair, or adjustment.

When selecting this type, it is crucial to verify the mounting bracket dimensions, bolt hole locations, and the jack's load capacity.

5. Electric Trailer Jacks

Electric trailer jacks typically operate on 12V power, using a motor to automate the lifting and lowering process.

Compared to manual jacks, electric jacks offer greater convenience; they are particularly well-suited for heavy trailers, RVs, and scenarios requiring frequent hitching and unhitching.

For heavy-duty trailers, electric jacks reduce manual effort and improve operational efficiency.

II. How to Choose the Right Trailer Jack?

When choosing a trailer jack, a higher load capacity isn't necessarily better; the choice should be based on the trailer's actual usage requirements.

1. Verify Rated Load Capacity

First, determine the trailer's tongue weight.

The jack's rated load capacity should meet or exceed the actual tongue weight it needs to support, with a reasonable safety margin allowed based on the operating environment.

For example, if the trailer has a heavy tongue weight, you should select a jack with a higher load capacity.

Note:

The trailer's gross weight is not the same as the weight the jack needs to support.

When selecting a jack, it is more important to understand the actual tongue weight and the support requirements for the front of the trailer.

2. Verify Mounting Method

The mounting method is another key factor when choosing a jack.

Common mounting methods include:

A-frame mount

Bolt-on mount

Direct weld-on mount

Swivel bracket mount

Before purchasing or replacing a jack, check the trailer's existing mounting structure to ensure the new jack can be installed correctly.

3. Verify Lift Travel

Lift travel determines how high the jack can raise the trailer tongue. When making a selection, first measure the height from the trailer hitch ball to the ground, then determine the required lift range based on actual connection and support needs.

If the trailer will be used across varying terrains or with different vehicles, a longer lift range generally offers greater versatility.

4. Selection based on usage environment

Different operating environments impose different requirements on trailer jacks.

Boat trailers:

Factors such as moisture, sand/silt, and outdoor exposure must be considered; prioritize surface finish, corrosion resistance, and structural stability.

Multi-purpose trailers:

Choose between swivel-mount, A-frame, or bolt-on jacks based on usage frequency and trailer weight.

RV/Camper trailers:

Consider manual or electric jacks for greater ease of operation.

Livestock and heavy-equipment trailers:

Higher load capacity and more stable mounting structures are usually required; consider heavy-duty weld-on jacks.

III. What else should be considered when choosing a trailer jack?

In addition to load capacity, mounting style, and lift range, consider the following aspects:

Tubing structure

Tube dimensions, wall thickness, and overall structural design affect the jack's stability and load-bearing performance.

Surface finish

Since trailer jacks are frequently used outdoors, the surface finish is crucial. Select the appropriate finish based on the specific operating environment.

Operation method

Common operation methods include:

Top-wind

Side-wind

Electric operation

Removable handle

Compatible with power drills

Different operation methods cater to various user preferences.

Base and wheels

Some trailer jacks can be fitted with single wheels, dual wheels, footplates (discs), or other support structures.

If the trailer is frequently used on mud, sand, or uneven ground, the base design is particularly important. A suitable base increases the contact area with the ground, enhancing stability.
