Video Transcript for Bulldog Trailer Jack - Side Frame Mount Jack - BD1823050383 Review

Speaker 1: Today we're taking a look at a Bulldog square jack. This jack has a lift capacity of 45,000 pounds and a static capacity of 90,000. It's ideal for horse, livestock, and heavy duty trailers. You can use this in tandem with Bulldog heavy duty two speed jack for landing gear applications. That jack is sold separately and available at etrailer.com.This jack is made from a durable steel construction. It features a black paint finish.

The handle is sold separately, so the side wind crank handle is sold separately, as well as the cross shaft that would connect this to another jack for dual jack application. That's sold separately as well. If you need anything related to this item, you can find everything you need at etrailer.com.It does feature the easy-to-access grease fittings. So on this side we have two grease fittings. That way you can attach a grease gun, pump in the grease, and lubricate the unit as needed.

So the easy-to-access grease fittings allow for easy maintenance.I also want to point out that it has the heavy duty steel leg band to provide extra strength and support, right there. Then internally we have a high efficiency double edge screw for nice, seamless operation. I also want to point out that you can see how this jack swivels on that foot. That's because it's a self-leveling sand shoe or a footplate that offers absolute stability, so that's going to really help prevent sinking when used on softer surfaces. Also it's great for terrain that might not be as level as we want it.

That sits on a pivoting point, so that way that foot can pivot as needed to self-level. That footplate measures 10 inches by 9 3/4 inches.This is a weld-on design, direct weld design, so it's a weld-on installation. Now I did take a measure of the overall height with it in fully retracted position, so from the bottom of the footplate to the top of the jack is about 33 1/2 inches, and then extended that increased to about 50 1/2 inches, which gives us a total lift of 17 inches. The outer tube is a square design and it measures 4 inches by 4 inches. That's going to do it for today's look at the Bulldog heavy duty square jack..

  • Side Mounted, Square Sidewinding Trailer Jack with 18 Inches of Travel
    For square, sidewinding jacks with a drop leg I can get you close to 18 inches of lift. You could potentially use Bulldog jack # BD1823050383 with 17 inches of lift. If you want to go above that though you would need a jack with a drop leg such as # BD182701 which has a total of 26 inches of lift. I have linked videos of both of these jacks for you.

  • Outer Tube Dimensions and Wall Thickness of Bulldog 22.5K Trailer Jack BD1823050383
    I went out to the warehouse to measure Bulldog jack # BD1823050383 for you. The outer tube is 29-7/8 inches tall. It has an outer measurement of 4 inches square. The wall thickness was just under 1/4 inch at 0.21 inches (using digital calipers).

  • What is Actual Weight Capacity of Bulldog Trailer Jack # BD1823050383
    The Bulldog Square Jack # BD1823050383 has a lifting capacity of 22,500 lbs and a static weight capacity of 45,000 lbs. That is not a trailer weight capacity as it is just a capacity for what the jack supports/can lift. It's really not that hard to crank either. Since it's rated so high it has a great mechanical advantage when it comes to lifting so it's easier than you'd think. Now if you were using the jack at it's max capacity and lifting something that weighs 22,500 lbs it would...

  • Recommended 2-Speed Jack for a 34 Foot Gooseneck Flat Bed Trailer
    I have a couple options for you but there isn't a electric kit for a 2-speed jack that we currently offer. The Bulldog powered-drive kit # BD1824200100 for a single speed jack is a solid option. To use this setup, you will need 2 single speed jacks like # BD1823050383 and the Bulldog powered-drive kit # BD1824200100 and the cross shaft # BDCS730300. You may also need the hand crank # BD8001090283. For a 2-speed setup, I recommend using the 2-speed tandem landing gear set # BD500153 and...

  • Replacement for Bulldog 1,200 lb Topwind Trailer Jack
    To get replacement parts for your Bulldog jack you need to know at the very least the specific model of jack and its capacity, with the exact model number being the best way. For example, the Replacement Sidewind Gear Kit # BD500106 is designed for Bulldog series 139, 159 and 170 jacks with a 5,000 lb capacity. That said, we do not carry replacement parts for a 1,200 lb Bulldog jack, which means your best option is going to be a new jack. There are no 1,200 lb topwind jacks, so I recommend...

  • Replacement Bulldog Tandem 2-Speed Jack Recommendations
    The only tandem Bulldog Jack set with 2 speeds that we offer is the Bulldog 2-Speed Tandem Landing Gear Set # BD500153. Which if you needed them individually you would want part # BD1823050383. This jack set has a 45,000 lb capacity and does not have a spring release handle like you said you have though which makes me think you may have something different like the part # BD182800 that you referenced which is actually a single speed jack. If you need a repair kit for the spring return...

  • Recommended Bulldog Square Sidewind Jack with Powered Drive
    The Bulldog Powered-Drive Kit # BD1824200100 referenced in your question can be used on the Bulldog Square Jack # BD1823050383, however it will reduce its capacity to 12,000 pounds so it may not be a good option. If you are needing a sidewind trailer jack with the 22,500 pound capacity that the Bulldog Square Jack # BD1823050383 provides, I recommend simply sticking with the base unit and using it as a standard manual jack. You can add the Sidewind Crank # BD8001090283 for easy operation. I...
