A trailer jack is an essential component used to support, lift, and level a trailer when it is parked. It also makes connecting and disconnecting the trailer from a towing vehicle easier and safer.
Choosing the right trailer jack is important for trailer stability, safe operation, and long-term performance. Different trailers require different types of jacks depending on their design, tongue weight, mounting position, and operating conditions.
CHENWEI Trailer Jacks, manufactured by Renqiu Chenwei Machinery Manufacturing Co., Ltd., are designed for different trailer applications. As a professional trailer jack manufacturer, we focus on product quality, reliable performance, and customized manufacturing solutions.
Different trailer designs require different jack structures and mounting methods. The following are some of the most common types of trailer jacks.
A-frame trailer jacks are installed in the center mounting hole of an A-frame trailer. They are commonly used on travel trailers, utility trailers, and RVs.
Available in different lifting capacities and travel lengths, these jacks provide stable support for trailer parking and hitching operations.
CHENWEI offers different A-frame trailer jack options, including top-wind and side-wind designs.
Swing-away trailer jacks feature a rotating mounting bracket that allows the jack to swing into a horizontal position when the trailer is being towed.
They are commonly used on boat trailers, utility trailers, and other trailers where ground clearance is important.
Depending on the model, they can be mounted using a bolt-on or weld-on bracket.
Direct-weld trailer jacks are permanently attached to the trailer frame using a welding bracket.
They are suitable for heavy-duty applications that require strong and stable support. Different square-tube and round-tube designs are available to meet various trailer requirements.
CHENWEI manufactures heavy-duty trailer jacks in different load capacities, including 5,000 lb, 8,000 lb, and 12,000 lb models.
Drop-leg trailer jacks feature an adjustable inner leg that can be quickly extended using a pin or spring-loaded mechanism.
This design reduces the amount of manual cranking required and allows the jack to reach the ground more quickly.
Drop-leg jacks are particularly suitable for heavy-duty trailers, agricultural equipment trailers, and commercial trailer applications.
CHENWEI provides 12,000 lb drop-leg trailer jacks in different operating configurations to meet specific customer requirements.
Choosing the correct trailer jack capacity is essential for safe and reliable operation.
One important factor is the trailer tongue weight, which is the downward force applied to the hitch by the loaded trailer.
For many conventional trailers, tongue weight is approximately 8%–12% of the total loaded trailer weight. However, actual requirements depend on trailer design and loading conditions.
When selecting a trailer jack, consider the following factors:
Load Capacity: Choose a jack with a rated capacity suitable for the actual load it needs to support.
Lifting Capacity: Make sure the jack can lift the trailer to the required height.
Travel Length: Consider the distance between the fully retracted and extended positions.
Mounting Type: Select an A-frame, pipe-mount, bolt-on, or weld-on design according to your trailer structure.
Operating Environment: Consider corrosion resistance, surface treatment, and exposure to outdoor conditions.
For example, a 2,000 lb trailer jack may be suitable for certain light-duty trailer applications, while heavier trailers may require 5,000 lb, 8,000 lb, or 12,000 lb models.
Important: Do not select a jack based only on the total trailer GVWR. The required capacity also depends on the actual load distribution, support points, and whether the jack is used for lifting or supporting.
A reliable trailer jack should provide more than just lifting capability. Several factors affect its service life and performance:
Strong Steel Construction: Quality steel materials help provide structural strength and durability.
Reliable Welding: Proper welding processes help ensure secure connections between components.
Smooth Operation: Well-designed internal components help improve lifting and lowering performance.
Corrosion Protection: Galvanized and powder-coated finishes help protect metal surfaces from corrosion.
Stable Footplate: A suitable footplate helps distribute the load and improve ground contact.
