3 Factors to Consider when Choosing a Trailer Jack
The trailer jack helps us make it easy to lift the end of the trailer to latch to the hitch of the vehicle. It also helps to stabilize the trailer while it is being latched. This article will specifically introduce the factors that need to be considered when choosing a trailer jack.
The height and load-bearing capacity of the jack
The trailer jacks have different heights and load-bearing capacities. They are detailed on the body of the trailer jack. Therefore, when purchasing, you must consider the height that can be reached when you expand to the limit.
The extension height must be such that the tongue of the trailer can be higher than the hook position of the tractor. This ensures that the jack can lift the trailer tongue high enough and easily connect and disconnect it from the hook.
The height is measured from the bottom or feet of the trailer jack to the point where it is installed. The location of the mounting point depends on the type of jack you have. Some of these measuring ends are located at the tailor bottom of their mounting flange.
The measuring end of another type of trailer jack called pipe installation is located in the middle of the installation pipe. There is another type of trailer jack that has a bolted bracket. This type of measurement ends at the centerline of this bracket. The height when retracted is as important as the extended height.
Another important item to consider is the load-bearing capacity of the trailer jack. The trailer jacks have different heights and different load-bearing capacities. If the load-bearing capacity of the jack is lower than the load-bearing capacity of the trailer, the jack may be damaged. Therefore, the load-bearing capacity of the jack should be higher than the weight of the trailer when it is loaded.
Weight of trailer tongue
It is important to understand the tongue weight of the trailer (TW). TW is usually 10% to 15% of the total trailer weight (GTW).
You are not sure what weight your GTW is, you can use the trailer tongue scaling device to weigh it. It is recommended that the jack should have at least the same load-bearing capacity as the TW.
In order to leave room for any kind of miscalculation, we recommend that the load-bearing capacity of the jack should be higher than TW.
Height of trailer tongue
When the trailer is level, you can measure the height of the trailer tongue from below the coupler to the level ground. After obtaining the height, make sure that the extension height of the jack is at least 4 inches higher.
This is to ensure that the tongue rises above the hook to facilitate connection and disconnection.
It is very important to choose a suitable trailer jack, if the trailer jack cannot support the load of the trailer, it may cause a safety accident. If you want to know more about the trailer jack after reading the above, you can get a comprehensive solution by contacting us.
