A Unified Hydraulic Lifting System (often called a unified jacking machine) is a special type of hydraulic lifting setup designed to raise or lower multiple points at exactly the same rate, regardless of differences in load at each jack. At The DeVillier Group, we have multiple unified jacking machines to use in different scenarios
How it works
- The system uses multiple hydraulic cylinders jacks connected to a central hydraulic pump and a manifold.
- The control unit regulates flow so that each jack receives the same volume of hydraulic fluid.
- Because equal fluid volume = equal piston travel, all jacks move in perfect synchronization.
- This prevents uneven lifting, structural stress, or even structural failure.
Why it’s used
The unified hydraulic lifting systems are essential when lifting loads that must stay level, such as:
- Building foundations during foundation repair or leveling.
- Houses, whether on a slab or on piers.
- Bridges and large concrete structures.
- Heavy machinery installation.
- Tank or vessel lifting.
Key advantages
- Precise, synchronized lifting at multiple points
- Compensation for unequal loads. One jack may carry more weight, but it won’t move any faster or slower
- Increased safety—reduces risk of twisting, cracking, or uneven settlement
- Centralized control makes complex lifts easier
Example scenario
If a contractor needs to lift a home at 24 points, a unified jacking system ensures each point rises, say, 1/8 inch at a time, regardless of how much weight each point carries. The entire structure is raised together, preventing structure failure and reducing stress on the home.
