Computer Controlled Static Anchor Tester Strand Anchorage 6500kN Servo

Product Features & Attributes
This computer controlled static anchor tester is used for static anchor strength testing of steel strands, specifically for testing the static anchor performance of wedge-type anchors, grips and couplers for prestressing tendons. It is core testing equipment for highway and railway bridge prestress quality testing.

Working Principle: The computer controlled electro-hydraulic servo loading system applies load via a high-precision load cell (6500kN). The computer controls and displays the test process, with an electro-hydraulic servo digital valve precisely controlling loading speed and pressure to determine anchor efficiency coefficient, total strain and other static anchor performance parameters.

Structure:

• Main unit: Load cell, frame, panel, jack and bearing plates, anchor plates, anchors, etc.

• Control cabinet: Control panel, motor pump, oil inlet/return valves, shut-off valve, solenoid directional valve, electro-hydraulic servo digital valve, piping, oil tank, etc.

• Computer control system: High-reliability software for data acquisition and processing

Technical Features:

• Computer controlled electro-hydraulic servo loading for high precision and accuracy

• Separate main unit and control cabinet design for convenient and stable operation

• Force measuring range 4%~100% (uninterrupted, equivalent to three ranges)

• Force accuracy better than ±1%, repeatability ±0.5%

• Piston stroke 200mm for standard test requirements

• Heavy-duty construction with thickened steel plates and reinforced screws

• Proprietary software with customizable settings

• Suitable for Φ21.8, Φ17.8, Φ15.24mm strands, single-hole and multi-hole testing

Technical Parameters:

• Displacement measuring range: 0~200mm

• Displacement accuracy: ±1%

• Relative resolution: ±0.5%

• Power supply: 380V

• Overall dimension: 900×900×3200mm (anchorage end) / 1100×900×735mm (control cabinet)

• Main unit net weight: 6000kg

Available in different specifications: different max test forces (5000kN, 6500kN, etc.) and different piston strokes (200mm, 250mm, etc.) to suit various testing institutions and standards.

Mainly used in highway bridge testing institutions, railway engineering quality testing stations, prestressed anchor manufacturers, research universities, third-party testing institutions, and more for static anchor performance testing of prestressing anchors, grips and couplers.
