  • How To Use Two Square Direct Weld Jacks Together
    The Square Direct Weld Jack part # TJD-12000SP-F2 can be used in tandem. The only thing you would need to do so would be a cross shaft which would be some sort of bar that attaches the two output shafts to one another. This is assuming you want both jacks to turn at the same time and not have independent operation with two handles. In regards to the cross shaft, you should be able to cut the Cross Shaft Extension Tube part # BDCS730300 to make it work.

  • Best Single Speed Jack To Pair With 2 Speed Square Tube Jack
    These are both great questions! Jacks with 2 speeds have the gears changed by either moving the handle to a different spot on the jack, or having the handle pushed in or pulled out to change the gear that is engaged- with this specific jack, you'll push the handle in or pull it out to change speeds. With a dual speed jack, the input speed is changed but the output speed does not change, so you would be able to use a 2 speed jack as the lead leg and a single speed jack as the follow-...

  • Dual Jack Landing Gear for Gooseneck Trailer Transporting Large Water Tank
    The weight of 1600 gallons of water, without the water tank's own weight factored in, is about 13,350-lbs. For such a high-weight application I suggest Bulldog Square Jacks # BD182804 and # BD182805 along with Connecting Rod # BDCS730300. Two jacks are definitely the way to go. If you wish to motorize this jack setup you can also add motor kit # BD1824200100. I also recommend you first determine the actual pin weight of the loaded trailer so that you can be sure to select jacks with...

  • Powered Jack Recommendation for Pro Series Heavy Jacks
    There is a motor that can be added to the Pro Series Jacks part # PS1400960376. I recommend the Bulldog Powered-Drive Kit for Single-Speed Jacks # BD1824200100 which can be used for single or double jacks using connecting rod # BDCS730300.

  • Recommended Landing Gear For 2004 CM Stock Livestock Trailer
    I spoke with my contact at Ultra-Fab about the Power Twin II Electric Stabilizer, part # UF39-941705. They recommend not using this system because of the movement any livestock would make in the trailer. They said any movement would cause additional stress on the system and they would not recommend it. This system is not designed to lift, as it is made to stabilize a steady load only. I recommend installing a tandem landing gear set like part # BD500154. This certainly has the capacity...

  • Can Two of the Bulldog Square Jacks Part # BD182805 Be Used in Tandem
    In order to use two of the Bulldog Square Jack part # BD182805 in tandem you will need to take out the vertical pinion bevel gear in the passenger's side jack and rotate that 180 degrees. This will allow you to use two of these jacks in tandem on a trailer. I have attached a review video that shows how to replace the gears for you which you could then use to help you rotate the pinion bevel. If you do not already have the handle for this jack then you can use part # BD015181. You will...

  • Availability of Cross Shaft for Use with Bulldog Jack BD182804
    We have the fixed cross shaft extension tube part # BDCS730300 which could be used to extend out the crank of the Bulldog Jack part # BD182804 that you referenced. This shaft is 72-3/4 inches long though which might be too long depending on the width of your trailer.

  • Which Jack Goes With Bulldog Square Jack BD183749 To Be Used As Landing Gear?
    We have exactly what you are looking for. The correct jack to pair with the Bulldog 2-Speed Square Jack - Drop Leg w/ Non-Spring Return - 26" Lift - 25,000 lbs # BD183749 you were looking at is the Bulldog Square Jack - Drop Leg w/ Non-Spring Return - Sidewind - 26" Lift - 12,500 lbs # BD182700. Both jacks have the same 12500lb lift capacity and 25000lb static capacity. Now you will also need a cross shaft like the 72-3/4" Long # BDCS730300, and a crank handle # BD8001090283. If...

The dual speed jack with gear box weighs 81 lbs. The hand crank weighs 4 lbs. If you are interested in the Telescoping Cross Shaft Extension Tube for Bulldog Tandem Landing Gear you will need part # BDCS730300.

  • Replacing Landing Gear on 2013 Jayco Seismic 3914 Toy Hauler
    8,000 lb jacks are going to be the highest rated landing gear sets we offer that will bolt right up to your trailer without modification. For that we have the Bulldog part # BD500162 which would work well. If what you really want something high capacity that would make easy work of your trailer the Bulldog Set part # BD500153 has a capacity of 45,000 lbs. You would need the extension tube part # BDCS730300 as well. You will need to modify the mounting brackets on your trailer to fit...

    For your 29-30 inches measurement, please look at the Replacement Lead Jack w/ Drop Leg for Stromberg Carlson Landing Gear - 29-1/2", # LG-179013 and its counter part the Follow Jack w/ Drop Leg for Stromberg Carlson Landing Gear - 29-1/2", # LG-179014. I suggest the Cross Shaft Extension Tube for Bulldog Tandem Landing Gear - 72-3/4" Long - Fixed # BDCS730300. You state that the bracket is at 11", if so you may need to remove adjust location and reweld. Please note the attached...

  • Powered Landing Gear Recommendation for a Loaded PJ Work Trailer
    There isn't a motor that can be added to the Pro Series Jacks part # PS1400960376. But if you are in the market for that style system, I recommend using # BD182804, and then add motor assembly # BD1824200100. You can also add # BDCS730300 and # BD182805.

  • Recommended Double Trailer Jack/Landing Gear For 20 Foot Tandem Axle Log Trailer
    For your 20 Foot double axle log trailer with 14K GVWR, I recommend the Bulldog 2-Speed Tandem Landing Gear Set - Weld On - 17" Lift - 45,000 lbs # BD500153. This system is rated higher than you requested but still falls within your budget. This is an extremely hard working landing gear set for your application. It has two cranking gears and a traditional gearbox with sidewind crank. With this system you will need the Fixed Cross Shaft Extension Tube for Bulldog Tandem Landing Gear...

  • Recommended Bulldog Electric Lift For 2014 Featherlite LQ Horse Trailer

You will simply add the Fixed Cross Shaft Extension Tube for Bulldog Tandem Landing Gear - 72-3/4" Long # BDCS730300 for that application. You can alternatively use the Bulldog Velocity Series Electric Landing Gear Jack - 24" Lift - 12,000 lbs # BD185400 if you prefer....

  • 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...

  • Can a Powered Drive Kit be Added to a Trailers Landing Gear
    The Bulldog Powered-Drive Kit # BD1824200100 that you referenced is designed to fit Bulldog single speed landing gear jacks with a 12k capacity. If that is what you have on your trailer this would work well for you. There isn't a universal motor kit that will work with most landing gear sets. You will need to determine who made the jacks of your trailer so that you can see if there is a powered drive kit available for it. Otherwise you will need to upgrade your jacks to a Bulldog...

  • 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...
