Video Transcript for etrailer Trailer Jack - Side Frame Mount Jack - TJD-7000 Review

Today we're going to be taking a look at the Square Direct Weld Jack. This included a footplate, as well as a dropleg. This utility jack is going to let you raise and lower your trailer. The square jack is going to provide more siloed capacity than round tube jacks. This jack is going to feature a lift capacity of 7,000 pounds, and a support capacity of 8,000 pounds. Again, it is a direct weld installation.

It's going to feature a topwind handle that's got a nice claw grip on it. It's going to allow for a nice comfortable grip when it comes to cranking and raising and lowering the trailer. Rally nice design, very easy to operate, nice fluid motion, I don't feel any kinking or binding. Another thing I want to point out about the handle it that it does fold over for easy compact storage when it's note being used. That's a nice design here at the handle mechanism. If we take a look at the handle radius, measuring from the center of where it mounts to the outer edge of that claw grip.

That's going to give us a handle radius measurement of 9 3/4". Now, I do want to point out that this jack also comes with the drop leg. That's going to allow for increased lift and it's going to save time when raising or lowering. Right down here, we're going to have a pin and a clip. What we can do is we can remove that.

Now the pin and clip is going to hold the leg at the desired location. I'm going to go and pull the drop leg all the way out so you can see it. This is your drop leg, you can see the multiple holes that it has right here. Now, this is going to offer 13 1/2" of additional travel separate from the travel of the jack. The center of this hole to the center of this hole, those are going to be separated by 13 1/2". Then it's going to be able to adjust an increments of about 3 3/8".

That's going to be the separation between each individual hole. Again, your drop leg is included. Really nice design, makes it very easy to adjust as necessary. The jack also allows for a very easy maintenance. Located right here, you're going to notice that it has a grease zerk fitting. That way you can attach your grease gun, pump in the grease and lubricate the internal components. Now, we're looking at a steel construction. On the outer tube, we're going to have a black powder coat finish. It's going to do a great job at resisting rust and corrosion. On the inner tube, drop leg and footplate, we're going to zinc finish. That's going to do a great job at resisting rust and corrosion as well. Now, the footplate is welded to the base of the drop leg. The footplate is going to give us an overall length measurement of about 7 7/8", with an overall width measurement of right around 6". That's going to do a great job at spreading out the applied weight, especially on softer ground. It actually going to help prevent sinking, and also increases stability. The inner tube is going to feature a hole on each side, going all the way around. That way you can re-position the drop leg and change the direction of the footplate to best fit your application. I'm going to take that measurement of the overall height. Measuring from the bottom of the footplate to the top of the handle mount. Now, it's in the fully retracted position. We'll do that measurement. That's going to measure 24 1/4". Now, I did that same measurement with the jack fully extended. That measurement increases the 39 1/2" which is going to give this jack a travel or lift of 15 1/4". The outer tube is going to give us an overall width, now this is a square design. That's going to measure 2 1/2" x 2 1/2". The inner tube is going to measure 2 1/4" x 2 1/4". That drop leg is going to measure 2" x 2". Now, again, keep in mind that it does have 15 1/4" of travel. The drop leg is going to provide an additional 13 1/2" of travel, and you can adjust that 13 1/2" of travel in increments of 3 3/8". That's going to do it for today's look at the Square Direct Weld Jack with the included footplate and drop leg. Again, this is going to have a lift capacity of 7,000 pounds and a support capacity of 8,000 pounds.

Product came in a good package and in a timely manner. I had to replace the jack on my 14ft dump trailer. The new jack was easy to install if you can weld. Also added 2 thousand of lifting capacity. Plus the grease zirk made it a no brainer. 425647

  • Is Replacement Internal Screw Available for Ram 7K Weld-On trailer Jack
    I spoke with my contact at Ram and they said that the internal screw for the 7K jacks are not something they carry replacements of so you will need to replace the whole jack. Even if this wasn't the case it would be a good idea to replace the entire unit anyways so that you can be confident all of the internal components are working properly. From what you described it looks like you either need part # TJD-7000S which is a weld-on 7K jack with a sidewind handle or part # TJD-7000 which...
