Strand Jack | Functions, Types, and Applications
The Strand Tension Jack is one of the most important tools in prestressed and post-tensioned systems, used in construction, bridge building, tunneling, and dam projects to tension steel cables (strands). These jacks utilize a hydraulic system to provide the necessary tensile force for concrete prestressing.
Components of the Strand Jack
Jack Body: The main structure of the device that holds the internal components.
Hydraulic Pump: Provides pressure to pull the strand and generate strong tensile force.
Gripper (Strand Holding Clamps): Holds the cable during tensioning and prevents slipping.
Cylinder and Piston: Converts hydraulic pressure into mechanical force to pull the cable.
How the Strand Tension Jack Works
Inserting the strand into the jack and special clamps.
Applying force through the hydraulic pump to tension the cable.
Monitoring tension using a pressure gauge or load sensor for high accuracy.
Locking the strand in place once the desired force is reached.
Releasing the jack and detaching it from the system without reducing the cable tension.
Types of Strand Tension Jacks
Mono Strand Jack: Suitable for tensioning a single cable at a time.
Multi Strand Jack: Designed for tensioning multiple cables simultaneously, increasing execution speed and accuracy.
Applications
Prestressed and post-tensioned bridges to enhance structural strength.
Dams and tunnels to improve resistance against high pressures.
High-rise buildings and towers utilizing prestressed concrete systems.
Why is the Strand Tension Jack Important?
- Enhancing the Strength and Durability of Concrete Structures
- Reducing Concrete Consumption and Construction Costs
- Creating Uniform Tension in Strand Cables
*In large stone cutting and moving projects, using the jack behind the peak as a specialized hydraulic tool can play an effective role in enhancing the accuracy and safety of operations.
