How to Determine the Support Capacity You Need in Your Landing Gear

If you will be using this landing gear to lift and lower your trailer onto a hitch ball or kingpin, then you should choose the jack you need based on its lift capacity. But, if you are just using it to stabilize or support a parked trailer, then you should focus on the jack's support capacity.

Heavy-duty jacks like this one stabilize about 25% of your trailer's total weight when it's loaded up. For example, a 50,000-lb trailer has a pin weight of about 12,500 lbs. For these legs to work, you'd need a set of landing gear with a combined lift capacity of no less than 12,500 lbs. If you only have one jack that can get the job done, that's great! In fact, this should work more efficiently, allowing you to spend less time cranking.

Note: Do not use landing gear to lift your trailer during tire changes or service work, because doing so will exceed the capacity of the landing gear.
