Types of Steel Strand Testing Machine

The steel strand testing machines produced by our company mainly include the following types:

 
 

Static Bogie Load Testing Machine

The anchor friction loss test device is designed and produced according to the principle stipulated in Appendix D of GB/T14370-2015. It adopts the single-end tensioning method, and installs a hollow hydraulic jack and pressure load sensor at the left and right ends of the test piece.

 
 
 

Metal Material Relaxation Tester

Metal material tensile stress relaxation testing machine is mainly used for tensile stress relaxation mechanical properties testing of metal materials (such as steel rods and steel wires) at room temperature.

 
 
 

Static Plate Load Test Equipment

Static plate load test equipment is a system of a steel load plate, a hydraulic jack, and a pressure system used to determine the load-bearing capacity and deformability of soils or sub-bases. The equipment applies a series of static, increasing loads to the plate while measuring the resulting settlement of the soil layer.

 

 

 

Features of Steel Strand Testing Machine

1. The rope structure with tension force can be measured directly without disassembly.
2. Light weight, simple structure and convenient operation, suitable for any occasion.
3. It has stable performance, high measurement accuracy, and has the function of automatic system compensation. When the specifications of the tested cable are the same as the cable number of the electronic tension machine, the accuracy can be within 2% within the rated range.
4. With fifteen kinds of wire diameter measurement functions, the measurement range is wider.
5. 2 to 6% of the maximum function (depending on the rope form and characteristics).

Applications of Steel Strand Testing Machine

 

 

● Material selection for engineering applications.
● Material quality assurance.
● Comparison of properties of new materials or processes.
● To identify material behavior under load.

 

Operation Method of Steel Strand Testing Machine

 

 

1. First, put the steel strand on the tensile frame of the testing machine, and fix the tensile frame on the testing machine.
2. Then, adjust the tensile speed of the testing machine to make it meet the requirements.
3. Next, adjust the tensile force of the tester to the desired value and record the tensile force of the tester.
4. Then, observe the fracture of the steel strand, and record the elongation at break, elastic modulus and other parameters.

FAQ

 

Q: What is a steel strand testing machine?

A: A specialized mechanical testing device designed to evaluate the mechanical properties of steel strands (multi-wire twisted steel products) by applying controlled tensile, fatigue, or relaxation loads. It is critical for ensuring steel strands meet safety standards in structures like bridges, high-rise buildings, and prestressed concrete.

Q: What is the working principle of a steel strand tensile testing machine?

A: The machine clamps the two ends of the steel strand (via specialized wedge grips to avoid slipping). A hydraulic cylinder or servo motor applies a gradual tensile force to the strand. Load cells and displacement sensors record real-time force and elongation data.

Q: What key mechanical properties does a steel strand testing machine measure?

A: Ultimate Tensile Strength (UTS): Maximum force the strand can withstand before breaking.
Yield Strength: Stress at which the strand begins to deform permanently (critical for prestressed design).
Elongation at Break: Percentage of length increase when the strand fractures (indicates ductility).
Relaxation Rate: Percentage of stress lost over time under constant elongation (prevents structural creep).

Q: What is the typical load capacity of a steel strand testing machine?

A: It ranges from 100 kN to 2000 kN (10–200 tons).

Q: How to calibrate a steel strand testing machine?

A: Use a standard force transducer (accuracy ±0.1%) to verify load readings at 20%, 50%, 80%, and 100% of rated capacity. Adjust via the control system if deviations exceed ±1%.

Q: How To Use Tensile Testing Machine?

A: To perform a tensile test, an operator will load a specimen into the two specimen grips of the machine. After loading the specimen, the operator selects the correct rate of movement for the material type. The tester then pulls the specimen apart until failure. The extensometer will record the distance moved and plot the movement on a graph electronically. Once completed, the graphic results are interpreted to understand the properties and behavior of the material.
