How Hitch Jacks Work

Towing unit jack, also known as trailer jack or tongue jack, is used to lift and stabilize the trailer to connect it to the tractor. This is one of many hitching accessories used to make towing easier.
Typically, the hitch jack is attached to the trailer's tongue, the long front beam that extends and connects to the tractor. The jack is fixed on the shaft and extends vertically to the ground. In some cases, the jack has a metal base or even wheels.
The hitch jack is different from the tire jack of most cars. It is a diamond-shaped metal plate. When you turn the iron, it will expand outward to lift the vehicle off the ground. A suspension jack commonly consists of a crank that turns the internal gear and extends from the metal shaft. The axle lifts the trailer off the ground to be appropriately hitched to the tractor.

Here's how to use trailer jack:

1. Connect the jack base to the road surface. This is usually achieved by releasing a pin that lowers the base.
2. Use the jack to raise the trailer to the extended position.
3. Carefully align the vehicle with the trailer tongue.
4. Turn the jack down until the trailer is on the hitch.
5. Connect the trailer to the jack on the tractor.
6. The next section will discuss the considerations when purchasing a hitch jack.

How to Use the tongue Jack Correctly

1. Check whether all parts are standard before use.
2. The regulations in the main parameters shall be strictly followed when using, and the superelevation and overload shall be avoided; otherwise, when the lifting height or lifting tonnage exceeds the regulations, serious oil leakage will occur at the top of the oil cylinder.
3. If the oil volume of the manual pump body is insufficient, N33 # hydraulic oil that should be fully filtered should be added to the pump before operation.
4. For the electric pump, please refer to the operating manual an electric pump.
5. The center of gravity of the heavy objects shall be moderate, the force point of the jack shall be reasonably selected, and the bottom shall be leveled. At the same time, the ground's soft and challenging conditions shall be considered, whether it is necessary to pad tough wood and place it stably to avoid sinking or tilting under the load.
6.  After the jack lifts the weight, it shall be firmly supported by the support in time. It is prohibited to use the jack as support. If you need to keep heavy objects for a long time, please select
7. If several jacks are required to lift simultaneously, in addition to correctly placing the jacks, multiple diversion valves shall be used, and a load of each jack shall be balanced. Pay attention to keeping the lifting speed synchronized. It is also necessary to consider the possible subsidence of the ground due to uneven weight to prevent the danger caused by the object's inclination to be lifted.
8. When using, first butt joint the quick coupling of the manual pump with the top, then select the position and tighten the oil drain screw on the oil pump to work. To lower the piston rod, slightly unscrew the hand wheel of the manual oil pump counterclockwise, unload the oil cylinder, and the piston rod will gradually lower. Otherwise, it will cause danger if the descent speed is too fast.
9.  The separated jack is a spring return structure, which can be taken out quickly after lifting, but the jack cannot be pulled by the connected hose.
10. Since the lifting stroke of the jack is small, the user must not exceed the rated stroke to avoid damaging the jack.
11.  Avoid violent vibration of the jack during use.
12.  It is unsuitable in workplaces with acid, alkali, and corrosive gases.
13. The user should check and maintain regularly according to the use condition.
