What is a Jacking System?

 

A jacking system is an electronic management system designed to control hydraulic movement. Because of this, it is also called a hydraulic jack system.It can automatically open or close control valves based on pressure feedback and manual settings. This helps compensate for small errors in the hydraulic pump’s output or differences caused by cylinder sizes, ensuring that the hydraulic system’s load stays within a specific range.The system mainly consists of a central controller, a hydraulic jack pump station, hydraulic cylinder jacks , and high-pressure hoses.

                 Types of Hydraulic Jack Systems

 

                                    Strand Jack System

 

Controlled by a computer and based on the principle of hydraulic synchronous lifting, this system integrates modern construction techniques to achieve synchronized lifting and lowering of large, heavy, and oversized components at high altitudes.It is especially suitable for lifting heavy components in confined spaces or indoors. The lifting capacity, span, and area are not restricted, and as long as there are suitable load-bearing lifting points, the lifting height is also unlimited.

 

                                   Bridge Jacking Systems

 

Designed for low-height, short-distance movement in heavy-load areas such as railway and highway bridges. It enables movement in three directions: X, Y, and Z axes.

 

                                   Synchronous Lifting Jack System

 

Utilizing VFDM technology and a PLC system, this system ensures precise synchronization and flow control. It can coordinate the operation of 4 to 99 single- or double-acting hydraulic cylinder jacks simultaneously.

 

                                   Building / Structural Jacking System

 

With multi-point displacement control, it allows precise positioning and movement in the X, Y, and Z directions. It is capable of bearing extremely heavy loads.

 

                                   3D Segmented Hydraulic Jacking System

 

This system allows segmented adjustment of various actions and supports both continuous and step-by-step operations. It can also coordinate the simultaneous operation of four or more units for precise positioning. Safety features include a hydraulic lock, lifting valve group, and mechanical lock.

 

                                   Hydraulic House Jack System

 

Designed for displacement control in the X, Y, and Z directions with multi-point movement capabilities. It is used for correcting house settlement, floor tilting, and structural relocation.

 

                                   Pipe Jacking System

​

Mainly used for underground pipelines, including water supply, sewage, gas lines, and power cables. The system pushes pipelines into the ground using hydraulic jacks, eliminating the need for extensive surface excavation, thus reducing environmental, traffic, and daily life disruptions.

                                  Advantages of the Jack Up System

 

The synchronized hydraulic jacking systems can lift and position any heavy or large structure, such as bridges and buildings.

 

Regardless of weight distribution, the system ensures all points lift simultaneously through calculations by a central computer, reducing the risk of bending or tilting.

 

The system maintains interface integrity, improves efficiency, and provides the safest and most controlled method for lifting and positioning large structures by minimizing manual operations during the lifting process.

 

                                  Features of the Synchronized Lifting Jack System

 

The system allows manual control of individual cylinders while achieving true computerized synchronous lifting. It supports up to 24 lifting points and can be used with both single-acting and double-acting cylinders of the same or different lifting capacities.

 

The system is equipped with a touchscreen and digital sensors, enabling easy setup, control, and navigation. It provides real-time load data and travel alerts for optimal safety. An integrated 10,000 psi hydraulic pump and controller ensure efficient operation.

 

The system powers interconnected hydraulic cylinders and offers various working modes to suit different project requirements. Integrated HMI technology monitors the precise movement and positioning of heavy loads.

 

All operations are controlled by a central unit that updates real-time lifting status.

 

The system monitors and manages the lifting, weighing, alignment, and load transfer of unevenly distributed heavy structures. It ensures precise synchronization of oil flow, cylinder stroke, and lifting speed.

 

The intuitive interface and clear menu design make control straightforward for technicians. Additionally, the system records and stores operational data at user-defined intervals, continuously monitoring the pressure and position of each lifting point for safe and accurate operation.

 

                                  How to Use a Hydraulic Jacking System?

 

The operating method of a hydraulic jacking system varies depending on its type. Always refer to the specific user manual for detailed instructions.

Here is a basic and universal guide for using a jacking system:

1. Place the cylinder jacks under the structure that needs to be lifted.

2. Determine the number and placement of cylinder jacks based on the weight, size, and other factors of the load.

3. Use high-pressure hoses to connect the hydraulic cylinder jacks to the hydraulic pump station.

4. Ensure the jacks are securely positioned against the load.

5. Set the lifting height, pulling height, and movement distance as needed.

6. Control the jacks to operate simultaneously for a stable lift.

​

Follow the user manual for maintenance and proper storage of the hydraulic jacking system.

 

        How to Choose the Right Synchronized Hydraulic Jacking Systems

 

Selecting the right jacking system depends on several key factors, including project requirements, load capacity, type, and brand.

Identify the object to be lifted and calculate its weight. Choose a hydraulic jack system with a rated load capacity at least 20%-30% higher than the actual requirement to prevent overloading.

Ensure the jack can achieve the required height and travel distance.

Select the Appropriate Type of Cylinder Jack. For fixed locations, prioritize functionality and durability over size and weight. For tight spaces, choose low-profile or compact cylinder jacks.Ensure the jack has safety features such as safety valves, self-locking mechanisms, and synchronization systems for precise operation.Consider reputable manufacturers like TorcStark and other well-known brands.Check for Special RequirementsExplosion-proof certification (ATEX compliance).Suitability for high-temperature or low-temperature environments.

Compatibility with specific hydraulic oils based on operational conditions.
