7000LBS Trailer Jack TJ715 Top Wind 15″ Lifting Square Tube

7000-pound trailer jack
The trailer jack is an essential component of safe towing. If you need to add or replace jacks on the trailer, the following information can help you choose among various jacks to find the appropriate one.
The basic function of a trailer jack is to raise and lower the trailer to connect the joint to the ball on the hitch and disconnect it from the ball. When the trailer is not connected to the towing vehicle, keep the trailer level. Stabilize the trailer for loading and unloading, as well as during trailer parking

How to choose a suitable trailer jack
Trailer jacks have different weights and lengths. Remember to consider the jack size in the retracted and extended positions. When extending, the jack must raise the joint sufficiently high to remove the hitch ball from the vehicle. The jack must be retracted far enough to leave the ground when driving. The following information can help you find a jack with the appropriate weight, capacity, and length for your application:
1. How to choose a suitable trailer jack to determine the height of the jack
Jack dimensions for retracted and extended positions
To determine if the jack is suitable for your trailer, you need to know the height at which the jack retracts and extends. These dimensions are usually used for jacks. They are transported from the bottom of the jack (including any possible supports) to the installation point. The installation point may vary depending on the type of socket. The standard A-frame jack is usually measured to the bottom of the mounting flange. Measure the pipeline's installation jack to the installation pipeline's center. Jacks with bolts on the bracket are usually measured to the centerline of the bracket.
Measurement of trailer tongue weight scale
2. Trailer tongue weight
The weight of the trailer tow bar (TW) is the downward pressure exerted by the joint on the ball head of the hitch. Usually, TW is 10% to 15% of the total trailer weight (GTW), and GTW is the trailer's weight when fully loaded. For example, a 5000-pound trailer presses a 500 to 750-pound TW onto a ball.
Choose a socket with a capacity that matches or exceeds your TW
If you are unsure of your TW, you can check our trailer towing reminder page for more information on how to weigh the trailer tongue. The Sherline trailer tongue weight scale can significantly simplify the weighing of the trailer tongue.
Due to manufacturing processes and costs, many jacks of different sizes and weights have similar prices. So you can use a jack that can easily surpass the trailer TW, but it won't be too big or too expensive. For example, you can use a 2000-pound jack for a 3500 GTW multi-purpose trailer, although the estimated TW is approximately 525 pounds.
3. Trailer tongue height
Measure the height from the ground to the bottom of the trailer connection joint with the trailer level and park on a level ground
The extension height of the jack should be approximately 4 "higher than the horizontal height of the joint so that you can lift it over the ball used to connect and disconnect the trailer
The jack should be retracted enough to be shorter than the connector height of a horizontal trailer.
When towing a trailer, it should also be retracted (or rotated to one side) to clean the ground. To ensure that the jack can clean uneven ground, the higher it rejects, the better.

Maintenance of agricultural trailers
In fact, maintaining agricultural trailers plays an essential role in extending their service life and effectively ensuring efficiency of agricultural trailers. However, this also requires us to regularly maintain and maintain agrarian trailers.
Generally speaking, the best maintenance for agricultural trailers is to maintain the turntable every six months by adding butter to the grease fittings on the turntable.
It is recommended to regularly tighten the wheel hub mesh and clean it with clean water.
Usually, agricultural trailers with brakes require the occasional addition of brake oil.
For agricultural trailers with support legs, agricultural trailer manufacturers recommend regularly removing oil and sediment from the support leg screws.
