31"-63" House Floor Jack, 4 Pack House Jacks for Lifting and Leveling, 18000 lbs Max Load Capacity Per Unit, Floor Jack Post Pole Jacks, Adjustable Support Beam Basement Leveling House Jack

Sturdy Steel Core ConstructionBuilt with American-standard heavy-duty steel, the jack body undergoes precision forging and full-body welding processes. Each weld point passes multiple ultrasonic inspections to achieve seamless integration, forming a solid support skeleton capable of resisting deformation under extreme loads. The high-strength load-bearing screw utilizes advanced cold-rolling and heat treatment technology, ensuring its surface hardness reaches HRC 45-50 while maintaining excellent toughness for smooth rotation and precise fine-tuning.Multi-Scenario Application SolutionsFoundational Support: Provides permanent/temporary support for basement main beams, effectively correcting floor sag Structural Reinforcement: Installs as auxiliary columns in garages, workshops, or attic spaces, increasing structural load capacity by 200%Emergency Scenarios: Serves as rapid deployment support equipment for post-disaster structural stabilization, water pipe burst temporary fixes, etc.Renovation Applications: Creates safe overhead work spaces during ceiling repairs, lighting installations, and HVAC maintenance
