1000 pound trailer jack
We produce reliable heavy-duty products such as freight trucks, multi-purpose drilling rigs (for pickup trucks), and livestock trailers. This jack is certified to comply with ASABE-S485 (American Society of Agricultural and Biological Engineers) standards and is recognized as a world-class standard in terms of performance for telescopic (screw) jack models.
When searching for trailer jacks, please ensure that your jack meets your requirements. Take our jack as an example. Circular jacks support light loads for connecting, separating, and fixing brackets. The square and heavy-duty models are very suitable for mixing medium to heavy-duty steel bars, coupling and decoupling, and storing trailers.
Rack and pinion jacks are the best choice for improving stability and can also support trailers with heavier traction frames.

Measurement method for trailer jack
In summary, you need to understand the three most important characteristics of a marine trailer jack:
1) Its weight capacity
2) Its bracket size
3) Its lifting height.
Please remember that the jack does not need to lift the entire trailer, only the trailer tongue, which accounts for approximately 10-15% of the total weight. Standard jack brackets should be suitable for most frames, but a jack with adjustable shelves is required if the frame height is greater than 3 inches or the depth is greater than 5 inches. As for the lifting height, marine trailer jacks typically use a combination of legs and inner tube extensions to generate total lift. Please remember that these three attributes will help you choose the best jack for your boat trailer.
Correct use of trailers
Before each departure, carefully inspect the components. For traction frame trailers, check the traction hook, traction frame, connecting pins, nuts, lifting rings, buffer springs, locking pins, etc.; For trailers using a turntable, it is necessary to check the center bolt of the turntable, as well as the safety chain, hub screws, steel plate springs, bolts, frame, etc., to see if they are loose, bent, or broken; Check the brake connecting pipes, wires, and other devices, such as protective nets, signal lights, etc., to see if they are complete if the connections are secure, and if the accompanying tools and items are ready.
2. The loaded goods should be evenly placed, and no additional or extended carriages are allowed. Overloading is not allowed. To prevent tire deformation, the carriage should be padded for long-term loading and parking.
3. When starting, the clutch should engage slowly and steadily. When tightening the trailer hook and feeling the weight of the trailer, release the clutch pedal when the tires start rolling; Strive for stability and agility when shifting gears; When shifting gears, if the trailer collides with the primary vehicle, it should change into gear and slide for a certain distance, then move forward as the speed of the front and rear cars gradually increases.
When driving, it is usually not recommended to slide out of gear. When encountering steep slopes or downhill turns, speeding is absolutely prohibited. When going downhill, select suitable low equipment in advance according to the length and gradient of the ramp, and control the speed by using the engine's resistance. When braking is required, the brake pedal must be slowly pressed to avoid emergency braking and prevent tire wear or tread peeling. The braking time should not be too long to prevent braking heating and reduce braking efficiency.
