7000lbs Trailer Jack

Trailer jack generally include external single action legs, external linkage legs, internal legs, and lightweight aluminum alloy legs. Trailer jack are the main components of agricultural vehicles, semi-trailers, and various other special trailers 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, Cold drawn lead screws, forged gears, and a floating structure design are used for the base. The lifting nut has good sealing performance and is placed in the lubricating grease chamber to receive new grease lubrication during the up and down movement of the support device. This saves time and effort, and has strong 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 a vessel, the vessel should consider its "wet" weight, including the vessel itself, plus the weight of all loaded equipment and fuel. It is important to distinguish between wet weight and dry weight, as dry weight is the weight specified by the factory without any fuel or additional rigging. In other words, when choosing a ship trailer jack, do not rely on your ship manual. 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!In general, the tongue jack should be able to lift at least 10% of the trailer's 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), your tongue jack should have a rated weight of at least 500 to 750 pounds.

Know trailer frame dimensions

Most people believe that the length exceeds 8 ½ Are foot trailers "oversized" and subject to additional restrictions? Each state also specifies the maximum length of ship trailers, as well as the maximum length of trailers and trailers, despite further changes. Jacking up longer ship trailers is more complex because they often have a more uneven weight distribution and a dual wheel design. More importantly, boatmen should be aware of the width of the trailer frame where the bracket is installed - most jack designs only apply to frames 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.

Know the height of the hitch

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