HYDRAULIC JACKING
HYDRAULIC JACKING APPLICATIONS
LEVELING AND REPOSITIONING
Hydraulic jacking plays a critical role in structural leveling and repositioning, providing precise control over the movement of large structural elements such as buildings, bridges, and heavy industrial equipment. This capability allows for correcting settlement, alignment issues, or relocating structures safely and efficiently. Hydraulic systems can handle delicate adjustments as well as substantial vertical or horizontal shifts, ensuring structural integrity throughout the operation.
​
LOAD TRANSFER SOLUTIONS
Hydraulic jacking facilitates efficient load movement and redistribution for a variety of structural tasks, from beam or column replacement to foundation strengthening through underpinning. By placing jacks at pre-determined points and applying controlled, incremental pressure, the existing load is lifted and carried by the hydraulic system. This allows for removing or reinforcing structural components and installing new supports—such as steel needle beams, micro‑piles, or reinforced concrete pads. Once ready, loads are gradually transferred back into the new / repaired support structure.
OUR APPROACH
1. STRUCTURAL EVALUATION
Each hydraulic jacking project starts with an extensive structural evaluation. Our experts assess existing structural conditions, determine precise load requirements, and identify any potential risks. This thorough evaluation forms the foundation for an accurate and reliable hydraulic jacking plan. Additionally, we integrate non‑destructive testing and advanced modeling techniques to validate our findings and refine the project scope before proceeding.
​
2. SYSTEM SELECTION / PROCEDURE DEVELOPMENT
Upon completion of the evaluation, we select and configure hydraulic equipment to meet the project’s specific requirements. Our engineering team then develops comprehensive jacking procedures - detailing load‑transfer sequences, specifying observation points and monitoring methods to safeguard structural integrity, and establishing redundancy measures and contingency plans. These procedures are circulated to the entire project team for review and alignment before any jacking operations begin.
​
3. EXECUTION
All equipment is staged and calibrated before jacking begins, with hydraulic jacks positioned and connected via manifold assemblies. The system is pressurized in a coordinated sequence using measured increments, allowing the structure to settle between lifts. Throughout this process, the team continuously monitors gauges, transducers, and other indicators to confirm readings stay within expected tolerances, pausing immediately if adjustments are needed. Once the desired load is reached, the jacks are slowly lowered in a controlled order to shift loads onto new or temporary supports. After verifying structural stability and alignment, all data and observations are compiled into a comprehensive execution report for client review.​
4. CONTINUOUS STRUCTURAL HEALTH MONITORING
Following the execution phase, a dedicated instrumentation and monitoring plan remains in effect for the duration of the project and into the stabilization period. We utilize a variety of sensor types including strain gauges, displacement sensors, accelerometers, inclinometers, pressure transducers, resistive load cells, etc. at critical locations feed data into Enable-designed monitoring systems, enabling real‑time visualization of load distribution and structural response. Data acquisition is configured to upload to the cloud allowing remote monitoring and alerting 24/7. This continuous oversight allows the engineering team to detect and address any rising anomalies before they compromise safety or project timelines.​​
RESEARCH & DEVELOPMENT
HYDRAULIC SYSTEM DESIGN
We design and develop custom hydraulic jacking systems in-house that incorporate automated, computer‑controlled power units. Electronic closed‑loop control and proportional valves allow us to synchronize multiple jacks, program precise loading and unloading rates and schedules, execute complex multi‑point lift sequences, and maintain uniform movement via sensor feedback, ensuring coordinated adjustments in demanding structural operations.
DATA ANALYSIS
​Our background in statistical analysis allows us to employ trend analysis, control‑chart monitoring, and outlier detection on the synchronized load and pressure readings throughout the lift and in post‑lift review. By calculating key metrics—mean, variance, and standard deviation—and applying confidence intervals, we quickly identify deviations from expected behavior. Regression and correlation analyses confirm that multi‑point load sequences remain aligned, while residual checks isolate any irregularities that could affect unloading or future lifts. These findings inform iterative adjustments to system parameters, continuously improving accuracy and reliability.
