Abstract
Selecting a reliable steel strand static load anchorage Testing Machine hinges on maximum Test force capacity, long-duration holding stability, full compliance with international & industry standards, precision measurement and unattended operation safety.
Key Takeaways
· Anchorage testers must match multi-hole anchor fixtures and meet core standards ISO 6934-4, GB/T14370-2007, JT/T329-2010 for engineering acceptance.
· Continuous load holding over 24 hours is supported, fully meeting long-time static load verification requirements for anchor assemblies.
· Four-bar heavy load frame with push-pull safety shielding ensures safe specimen loading and anti-splash protection during rupture.
· Independent hydraulic oil source cabinet with imported core hydraulic parts delivers stable, low-fluctuation loading performance.
· Built-in English HKtest software automatically calculates anchor efficiency coefficient ηₐ, fixture efficiency ηg and total strain εAPU for standardized test reports.
Understanding Static Load Anchorage Testing Machine Ecosystem
Similar to stress relaxation testers, a qualified static anchorage testing machine consists of two core modules: high-stiffness four-column bearing frame and electro-hydraulic servo closed-loop measurement & control system.

Mechanical Structure & Stability Advantages
1. Four-bar heavy-duty bearing frame Constructed with left bearing beam, right bearing beam, cross tie bars, partition beam and fixing nuts to form a rigid closed load frame. The push-pull safety net wraps the whole frame for easy specimen loading and anti-splash protection when specimens break under tension. Backing plates fix anchor rings, while column load sensors connect the through-core jack for accurate force transmission.
2. High-precision displacement sensing assembly Mounted on the through-core jack piston to track cylinder travel. Photoelectric encoder paired with linear guide bearings enhances lateral force resistance of the piston rod; built-in reset springs automatically reset measuring plates after test completion, ensuring consistent deformation measurement accuracy.
3. Split independent hydraulic oil source cabinet Separated design of main machine and power unit reduces heat interference to test frame; modular hydraulic layout simplifies maintenance and daily inspection.
Intelligent Electro-Hydraulic Control & Software Core Functions
· Dual closed-loop control modes: constant-rate loading, constant-rate deformation, seamless switching without load impact
· Automatic calculation of core anchorage indexes: anchor efficiency coefficient ηₐ, fixture efficiency ηg, total strain εAPU at ultimate tension
· Real-time dynamic display of load-displacement curves during full 24h long holding test
· One-click digital calibration for load and displacement channels, simple periodic calibration operation
· Complete test data storage: save specimen parameters, full-process curves and test reports for recall and review
· Customizable test report template, editable with enterprise logo, fully matching third-party inspection filing requirements
· Automatic overload interlock protection when force exceeds full scale threshold
Multi-Layer Safety Protection Design
1. Transparent push-pull safety shield: blocks fragment splashing when steel strand ruptures
2. Software programmable overload shutdown threshold, real-time force monitoring
3. Mechanical stroke limit block to prevent over-travel damage to jack piston
4. Electrical protection: over-current, over-voltage, overload automatic power cut-off for hydraulic power unit
5. Separated oil source cabinet avoids hydraulic leakage risks near test specimens
