- BD500153

I purchased this landing gear a while back for my 25' gooseneck trailer that I haul heavy equipment with. The trailer originally had only a single 10,000lb single speed drop leg jack and was not a very stable setup. The old jack just wasnt cutting it and I needed a more heavy duty set up that I could depend on. I mounted this landing gear and it was one of the best improvements I have made to the trailer. Instead of the old single setup mounted between the neck beams that was very hard to crank under load, the tandem set now provides stable load support across the front and is very easy to crank in low range under load. One feature I liked about this landing gear was they dont have drop legs. The sand shoes are a fixed mount with large pins and wide shoes. Same as those on semi trailers. The lack of a drop leg is no problem as I keep a couple of 6"x6" blocks in the trailer and slide them under the shoes before I jack the trailer up. The blocks give added lift to the jacks and also keep the shoes out of the dirt. These jacks are geared a little higher in high range than smaller jacks so in the time it would take to pull a drop leg and crank down I can have the blocks set up and jacks cranked down. Once the load is felt just switch to low and cranking is effortless. Keep the shoes and legs clean/maintained and they will never rot/fai/bend like the drop legs on smaller capacity jacks. Last thing is I would recommend is to remove the two speed gearbox cover and pack it full of grease before the first use. Two speed boxes come from the factory with very little grease. Intial packing will help prevent excessive break in wear. There are grease fittings on both jacks which can be topped off a couple times a year there after. I wanted a very heavy duty landing gear set that would out last the trailer and one that was rated for more than the trailer will hold. This set has exceeded my expectations. 272867

  • Solution for Needing 2 Speed Landing Gear for Flat Bed Gooseneck Trailer
    There's a slim chance that's possible, but I would need to know what jacks you have on your trailer first to determine if there's a way. I will say that most likely there won't be and only solution will be a new landing gear set that is two speed like the Bulldog 2 speed kit part # BD500153 which has a 45,000 lb capacity.

  • Bolt On Trailer Landing Gear Jack for a 24,000 Pound Trailer
    Bulldog jack # BD500154 is very much overkill for a 12 ton trailer but also one of only a few we are going to have for 24,000 pounds. The manufacturer has not provided us with images and we have not yet had the item in to take pictures. But it is a landing gear set not unlike # BD500153 which is the weld-on counter part set. We also have a 45K option, # BD1839060383, bolt on. For 25K we have some options that I have linked for you but they are all weld on.

Apart from that you may want to check out an electric jack set like the Ultra-Fab Deluxe Electric Landing Gear Set # UF17-943010 which has a combined 12,000 lbs of capacity, which may work and offers 38" of lift.

  • 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 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...

  • Recommended Gooseneck Trailer Powered Landing Gear for Completely Weather Exposed System on Trailer
    When landing gear like # LG-1 is used on exposed trailers the electric component needs to be covered. Most of the time this is done with a custom sheet metal box as it doesn't take much just to shield the motor from the elements. The legs are powder coated and the gear box is aluminum, so you won't have issues with them being exposed, but the motor is another story. Your other option is to use a jack like the Bulldog Velocity Series Electric Landing Gear Jack # BD185400 or for a...

  • 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...
