A trailer tongue jack like Pro Series # PSEA20000103 has a rated lift capacity of 2000-lbs. Two of them would have twice the capacity but this type of jack is typically used singly on an A-Frame trailer. Other types of jacks like a 5th wheel dual-jack landing gear kit # BD500162 consists of two separate but interconnected jacks each able to lift 4000-lbs which gives this kit its overall 8K rating.

In comparison a stabilizer scissor jack like # UF48-979002 will have a much higher weight rating (13K for the two) since these jack do not lift that much weight; they simply support/stabilize it to keep a trailer steady.

Other jacks like Bulldog 2-Speed Jack # BD183816 will have two ratings, one for lifting and one for holding. This jack has a lift rating of 10,000-lbs and a holding (static) capacity of 12,000-lbs. For more information on jacks please refer to the linked article.
