Professional Guide To House Floor Basement Jacks

1. Product Overview and Working Principles of basement jack

1.1 Basic Definition and Features of house floor basement jack

House Floor Basement Jack is specialized equipment designed for structural support in buildings, primarily addressing issues caused by foundation settlement and structural aging. 

Key features include:

- Load-bearing capacity: 3-20 tons

- Height adjustment: Precision mechanisms with millimeter-level accuracy

- Structural stability: Scientifically designed force distribution

- Safety protection: Multiple anti-loosening devices

1.2 Core Working Principles

The support system operates through:

1. Vertical support principle: 90-degree design for optimal force transfer

2. Load distribution mechanism: Disperses pressure through large contact surfaces

3. Progressive adjustment system: Allows gradual precision adjustment to prevent secondary damage

1.3 Main Components

Standard support jacks include:

| Component | Function | Material Requirement |
