Video Transcript for Bulldog Camper Jack - Landing Gear - BD182815 Review

Today were going to review part number bd182815. This is the Bulldog Square Jack, the side-wide crank and the drop leg with the spring return. This heavy duty square drop leg jack has a front facing plunger pin. Has an easy access gear box. Its perfect for agricultural, construction, livestock, or heavy duty utility applications. The side-wide crank is sold separately.

This jack is constructed of a seven gauge alloy steel which will offer superior strength and durability. The inner tube and the outer tube are painted to make them weather resistant. Again this gear box, by removing a couple of screws, is easy accessible for routine maintenance. On the front here there are two zerk fittings which will make it easy to grease the gear box. The drop leg does have a spring return.

It does increase the overall extensive for maximum adjustability. The plunger pin is position in the front. This jack is a direct weld design. Now this jack can be paired with either part number bd183816 or bd183903 for use in a tandem application. The standard foot plate is included.

Just to show you theres the side-wide crank. Cranking it clockwise would raise it and cranking it counter-clockwise would lower it. To adjust the spring return you have a plunger pin here on the side that if you pull it out, lock it into place you can pull down your spring loaded drop leg. Therell be adjustments holes in it. When you find the right adjustment you need it at just release the pin and it would insert into the hole and keep it at that height you need it.

Once youre done you need to raise it back up you just pull it out and lock it. It has a spring return so it will automatically spring all the way up to the up position I do want to give you a few dimensions on this. This jack right here is in the fully retracted height. We measure that fully retracted is 28 and a half inches. Right here I pull another same exact jack and to save time I already cranked it out. Its at the fully extended position. If we measure that would be 41 inches. That means your maximum lift on this jack would be 12 and a half inches. Now the drop leg on this jack will give you an extra travel of 13 and a half inches. The square tubing width on this is four inches. This jack does have a static weight capacity of 12,000 pounds and a lift weight capacity of 10,000 pounds. It does come with a limited five year warranty. That should do it for a review on part number bd182815.

We have been propping up the goose neck flatbed for years. The Bulldog hitch was easily installed, makes hooking up and dropping our trailer a lot easier and safer, and seems better built than the original. Wish we had done this a long time ago! 174737

Still easy to use and holding up well, great purchase!

Great product. Have seen lots of them in use. 131970

- BD182815

This is a replacement for the original jack that came with my trailer. I am hard on equipment as I build fences and have to drag across terraces and through stream crossings. I carry a skid steer, four wheelers and attachments. This jack is lower geared than the previous one on the trailer and is much easier to raise with weight still on the trailer...slower, but a great improvement. It's nice to be able to unhook without having to unload all the time! 77396

Still working great! No problems. Great product. Thanks for the follow up

Product arrived yesterday. It was not packed very good and the box was torn all to pieces. Not damage to jack except for some scratched up paint. Otherwise the service was great. Jack is already on trailer and getting ready to install the electric motor. Thanks 46222

Excellent product, I searched locally and on the internet for this product and nobody even came close to etrailer's price. And it shipped the same day! Thanks much! 8205

  • Electric Conversion Compatibility for Holland Binkley Model 48000 Series Jack on Horse Trailer
    The Holland Binkley model 48,000 series jacks are very similar to the Bulldog Square Jack - Drop Leg w/ Spring Return # BD182815 which can utilize the Bulldog Powered-Drive Kit for Single-Speed Jacks w/ 12,000-lb Capacity # BD1824200100. Your current jacks are not compatible with the kit to my knowledge so you would need to replace the jacks in order to upgrade to the motor kit. Another option is to use the Bulldog Velocity Series Electric Landing Gear Jack - 24" Lift - 12,000 lbs...

  • Bulldog 12000 lb Powered Electric Jack Replacement Motor
    To replace just the motor for your 12000 lb Bulldog single-speed jack (like # BD182815) you will just need motor # BD1046130-00. I've attached a video of the motor being installed for your convenience. To replace the dual-output motor for Bulldog electric 5th-wheel landing gear (like # BD500161), use part # BD500359.

To add a motor to this style of jack, I recommend the Bulldog Powered-Drive Kit for Single-Speed Jacks w/ 12,000-lb Capacity # BD1824200100. This will include the wiring harness, motor, circuit breaker, and rocker switch in weatherproof box. This will allow you to simply connect to a 12V battery....

  • Can I Replace Just One Jack on 2012 PJ Flatbed Trailer With Bulldog 2-Speed Jack, Part # BD183816
    In order for your existing single-speed trailer jack to work with the Bulldog 2-Speed Jack - Drop Leg w/ Spring Return, part # BD183816, it is essential that the existing jack have a cranking ratio (the number of handle turns that moves the jack one inch) that is the same as the 9-turns-per-inch high gear ratio of the Bulldog. If the two jacks do not have the same turns ratio, then the trailer will elevate unevenly, creating a safety hazard. My contact at Bulldog tells me that if the...

    If you have a single speed, Bulldog jack rated for 12,000 pounds, like # BD182815, you would need the complete powered drive kit, # BD1824200100. If you have a 2-speed jack, the correct powered drive kit is # BD1824180100. The 2 speed motor and single speed motor are not identical so you would need to select the correct one based on your Bulldog jack. There will be some welding required that a qualified welder in your area would have no problem with.

  • Whats the Difference Between Spring Return Jack and a Non-Spring Return Jack
    A spring return in this regard is a mechanism that helps when you are lowering or raising a trailer onto a gooseneck ball. Due to the slow jack speed and the far distance that the foot of a jack has to go when you are raising a trailer there is a pin you can pull in the leg of the jack that will lower the inner section of the jack to take up the majority of the distance that the jack foot has to cover. Well, when it comes time to lower your trailer onto your truck and drive off you...

These jacks will both work with the Bulldog Powered-Drive Kit, # BD1824200100, that you referenced and feature 10,000 lbs of lift capacity. These are the best heavy duty jacks we carry at this time, and we do not have a hydraulic trailer jack option available.

    According to my contact at Bulldog, you can use two of the Bulldog Square Jacks # BD182815 for your trailer.

You will need a connecting rod and a crank handle like the Bulldog Replacement Side Wind Jack # BD800090. I have included links to the parts listed above as well as a video for your reference.

    If you ran the Bulldog Jacks part # BD182815 and # BD183816 on a trailer that weighed a max of 24k you'd be good. Each of these jacks has a 10k lifting capacity so you'd have 20k of lifting capacity which is more than enough for the front of a 24k trailer. The jacks are not rated for the total trailer weight and are instead just rated for the amount they can lift vertically.
