Video Transcript for Review of etrailer Trailer Jack - Side Frame Mount Jack - TJD-8000S

Today we'll be taking a look at the Square Direct Weld Jack with Footplate. This jack is going to help us lift and lower our trailer, so that we can get it supported and leveled off whenever we need to go and hook up to our vehicle again. It's made of a durable construction. Our top piece, the handle, the inner tube and our footplate all have a zinc coating to help resist any kind of rust or corrosion. The footplate is welded in place, so it's going to be nice and secure and that's going to give us some additional lift with this jack since we'll have five different adjustment points and those are each about three and a half inches apart. To adjust those you'll just pull the clip on the one side here, pull out that pin and then that drop leg will adjust down.Let me get my pin put back in and then we'll go over some measurements for the jack.

There we go. Okay. So over . The total height for our jack whenever it's fully retracted is 25 and an eighth inches. And that's from the bottom of that footplate to the top of the jack.

When it's fully extended, it's going to be 40 and a quarter inches. So our total lift will be 28 and seven eighths inches. The screw travels, so the screw inside, that's going to give us 15 and an eighth inches of that lift, and then the rest of that comes from the drop leg and that's going to give us 13 and three quarters inches of lift.The capacity that this can actually lift is 7,000 pounds and it has a support capacity of 8,000 pounds. The outer tube measures two and a quarter inches wide. The inner tube measures two inches.

Our footplate from edge to edge measures seven and seven eighths by five and seven eighths inches. So it's going to help to spread out the weight of our trailer and help to keep us from sinking into any kind of soft ground like sand, gravel or loose dirt. As far as the swing on our handle, it has a radius of seven and three quarters inches. That's from the attachment point there to the center of the handle, so that's how big the swing is on the one side.And then our handle is about .. This moved out here.

It's about three and three quarters inches wide, so it gives you enough space to get your hand on there and get a good grip. The distance from the jack to the outer edge of that handle, just to let you know how much space you have there, it's about five and a half inches or about five and five eighths. It does have a grease Zerk installed there, so you can make some easy maintenance or do some easy maintenance with your jack to keep everything nice and lubricated and moving smoothly. Overall, it's going to be a great jack for your application. It is a weld on design. And that's going to do it for our look at the Square Direct Weld Jack with Footplate.

I like the direct weld jacks. But I wish at least the outside tube was thicker with a little moe clearance with the inner tube. I put them on a 2020 Griffon 14’x7 ton dump trailer. I could not weld them directly to the trailer frame because I would not be able to crank the handles. I had to weld 1/2” x6” plates to the jacks to off set them farther from the fenders. I might use a little to much heat. Before I welded them the crank handles were very free. After welding they bind a little bit. But they still work great.

Makes a great stabilizer jack for my trailer when loading my tractor. Dont have to worry about putting wooden blocks under the back or have to carry any around anymore.

- TJD-8000S

I just received two of these jacks and had them welded on the rear of my flatbed trailer. They appear to be quality products and were relatively easy to weld on my trailer. I trailer a Kubota KX040 excavator, SVL 75 track loader and a TLB L45 backhoe and when loading each of these on my trailer, it raises the back end of my truck making it unsafe, until which point the equipment is situated properly on the trailer deck.

This is an Excellent part in my trailers. The strongest, and the best price from etrailer.

Review from a similar Ram Square Sidewind in Trailer Jack

Great quality jack. I had never owned a heavy trailer previously. Grew up with 3,000 pounders and finally purchased 18 ft enclosed. It came with an a-frame 5,000 pound jack which was toast after a couple of uses the way I organized the trailer. Purchased a replacement which lasted 2-4 weeks before it was no longer working. Purchased a 2nd replacement 5,000 pound a-frame jack which lasted a week. For those who dont know....don't go through the headache and money. Get yourself a square jack. Get this one or something else heavy duty if its going to be a heavy load. Once you have 1 of these you'll never go back! No other option couldn't be more satisfied.

Review from a similar Ram Square Sidewind in Trailer Jack

Was having issues with the trailer lifting the backend of my truck when I loaded tractors. When I would drive the tractor on the back of the trailer would go down from the weight on the rear which caused the front of the trailer to lift the backend of my truck. So, I bought a couple of the Square, Pipe Mount, Swivel Jacks with Footplates and a Drop Leg. They are Topwind, 7K, Jacks. I had them welded on. This should stop the issue I'm having. I know the 7K was a little over kill but the price was great.

The Jacks are working great. Definitely fixed my problem and make easy for me to load heavy equipment now. Thanks again for a great product!!!

  • How Does Square Direct Weld Jack w/ Footplate Weld On to Trailer
    The Square Direct Weld Jack w/ Footplate # TJD-8000S welds directly to the frame of your trailer. They're universal in design so where they are mounted depends on the application. You put the jack in the proper location for your trailer and weld on both sides of the jack, the length of the attachment point. I included a photo and linked the parts for reference. I recommend having a qualified shop, or welder install it if you are not comfortable or have not welded before.

  • Recommendation for Weld-On Rear Jacks for 2020 Griffin 7 Ton Dump Trailer
    For a pair of rear stabilizer jacks that you can weld directly to the frame of your 2020 Griffin 7 ton dump trailer, I recommend two of the etrailer Square Direct Weld Jack part # TJD-8000S. It measures 25-1/8 inches from the bottom of the foot to top of jack when retracted and 40-1/4 inches when fully extended. Each jack has a capacity of 7,000 lbs, for a combined capacity of 14,000 lbs that will work perfectly with your 7 ton dump trailer. I've attached a video that goes over all...

  • What is Difference Between etrailer # TJD-8000S and # TJD-7000S Trailer Jacks
    The big difference is the orientation of the foot plate on both jacks. One just has the rectangular shaped foot plate rotated 90 degrees from the other. Aside from that they both have the same capacities and travel.
