7000-pound trailer jack
Trailer jacks typically include external single-acting legs, external link legs, internal legs, and lightweight aluminum alloy legs. Trailer jacks are the main components of agricultural vehicles, semi-trailers, and other professional trailers, used for support and lifting after installation. The trailer jack produced by the company can meet the requirements of different types of agricultural vehicles. They adopt a compact outer tube and reinforced installation support plate structure, with a base designed with cold-drawn screws, forged gears, and a floating frame. The lifting nut has good sealing performance and is placed in the grease chamber to receive new grease during the up-and-down movement of the support device. This saves time and effort and has a solid load-bearing capacity.

What size trailer jack do you need for your ship
Know the weight of your ship
When determining the size of the trailer jack required for the vessel, the vessel should consider its "wet" weight, including the vessel itself, plus the weight of all loading equipment and fuel. It is important to distinguish between wet weight and dry weight, as dry weight refers to the weight specified by the factory without any fuel or additional rigging. In other words, do not rely on your ship manual when choosing a ship trailer jack. The fuel on board weighs about 7 pounds per gallon, so depending on the size of the fuel tank on board, it may weigh 500 pounds or even more when fully loaded!
Generally speaking, a tongue jack should be able to lift at least 10% of the trailer weight, preferably 15%. This means that if your trailer has a total weight of 5000 pounds (which is common when adding bathroom/shower/sink water), the rated importance of your tongue jack should be at least 500 to 750 pounds.
Understand trailer frame dimensions.
Most people believe that the length exceeds 8 ½. Is the foot trailer 'too large' and subject to additional restrictions? Each state also specifies the maximum size of ship trailers and the maximum length of trailers and trailers (despite further changes). Jacking up longer ship trailers is more complex as they typically have a more uneven weight distribution and dual wheel design. More importantly, boatmen should pay attention to the width of the trailer frame when installing the bracket - most jack designs only apply to structures 3 inches high and 5 inches deep, and boatmen with trailer sizes exceeding these must ensure that the trailer jack can be adjusted to fit larger frames.

Understand the height of the hitch.
Most trailer hitch receivers are installed approximately 14 inches above the ground, although the spherical installation size may significantly change the height. To calculate the appropriate lifting height required, it is necessary to first measure the height of the tractor hitch and then increase it by 4-5 inches
