Overview
The YANRUN 300kN Computer-Controlled Hydraulic Horizontal Tensile Testing Machine is a high-capacity, horizontally configured mechanical testing system engineered for static tensile evaluation of large-scale structural components, cables, anchorages, prestressed tendons, railway couplers, and heavy-duty fasteners. Unlike vertical frame configurations, its horizontal layout accommodates extended specimens—up to 10 meters in effective test length—and integrates a robust hydraulic actuation system with closed-loop force and displacement control. The machine operates on the principle of servo-controlled hydraulic loading, where a 300 kN capacity double-acting piston cylinder applies axial tensile load while high-stiffness load cells and linear displacement transducers provide real-time feedback to the industrial PC-based controller. Designed for compliance with international mechanical testing standards—including ASTM E4, ASTM E8/E8M, ISO 6892-1, and GB/T 228.1—the system delivers traceable, reproducible results suitable for quality assurance, R&D validation, and third-party certification workflows in infrastructure, energy, and transportation sectors.
Key Features
- Horizontal configuration enabling up to 10 m specimen length and 1 m piston stroke—ideal for full-scale cable, rope, and rail component testing
- 300 kN hydraulic actuator with dual-mode operation: rapid no-load positioning (≥100 mm/min) and precision-controlled loading (0.5–80 mm/min)
- High-fidelity 300 kN load cell calibrated to ≤ ±1% FS accuracy across 4–100% full scale, compliant with ISO 376 Class 1 requirements
- Dedicated industrial control cabinet with integrated low-voltage starter, pressure relief valves, and welded seamless steel hydraulic piping for long-term operational stability
- Real-time data acquisition and display via embedded Windows-based industrial PC with 19″ LCD monitor and HP A4 inkjet printer for hard-copy report generation
- Modular mechanical architecture including rigid oil cylinder base, spherical jointed piston head, movable crosshead, reinforced tie rods, rear fixed beam, and interchangeable grips with pin-type anchorage
Sample Compatibility & Compliance
The system supports cylindrical, rectangular, and irregular-section specimens ranging from Ø10 mm wire ropes to Ø80 mm structural bolts and 50×100 mm concrete-embedded anchor assemblies. Grip adaptability includes wedge-type, clevis, and custom-threaded fixtures. All mechanical and electrical subsystems conform to CE machinery directive (2006/42/EC) safety principles. Force measurement uncertainty is validated per ISO/IEC 17025-accredited calibration protocols. Data integrity meets GLP/GMP audit requirements through timestamped, non-editable test logs; optional 21 CFR Part 11-compliant electronic signature modules are available upon request.
Software & Data Management
The proprietary YANRUN TestMaster™ software runs on Windows OS and provides synchronized acquisition of load, displacement, and strain (when extensometer-equipped). It supports programmable multi-step test profiles (preload → ramp → hold → unload), automatic yield point detection per ISO 6892-1 Annex C, and export of raw ASCII or Excel-compatible .csv files. All test records include metadata such as operator ID, environmental conditions (ambient temperature/humidity), calibration certificate IDs, and instrument firmware version. Audit trails log user actions, parameter changes, and report generation events—enabling full traceability for ISO 9001 internal audits and regulatory submissions.
Applications
- Tensile qualification of pre-stressed concrete tendons and post-tensioning systems in bridge and building construction
- Proof testing and fatigue pre-screening of marine mooring chains and offshore lifting slings
- Mechanical verification of railway draft gear, coupler assemblies, and brake rigging components
- Validation of high-strength alloy cables used in suspension bridges and cable-stayed structures
- Material characterization of high-carbon steel wires, stainless steel strands, and composite-reinforced polymer cables
- Third-party certification testing for EN 10204 3.1/3.2 material declarations and ASME B31.4/B31.8 pipeline component approval
FAQ
What is the maximum specimen length this machine can accommodate?
Up to 10 meters of effective test length between grips, enabled by its horizontal frame geometry and 1-meter piston stroke.
Does the system support extensometer integration for strain measurement?
Yes—standardized analog and digital interfaces (LVDT, strain gauge, and video extensometer inputs) are provided for high-resolution strain acquisition.
Is the force calibration traceable to national metrology institutes?
All load cells are factory-calibrated against NIM (National Institute of Metrology, China)-certified reference standards, with optional UKAS or DAkkS-traceable certificates available.
Can the machine perform cyclic or hold tests?
Yes—TestMaster™ software supports multi-segment load-displacement programs including dwell periods at specified loads or displacements, with configurable ramp rates and dwell durations.
What maintenance intervals are recommended for the hydraulic system?
Oil filtration and pressure valve inspection every 500 operating hours; full hydraulic fluid replacement and seal inspection every 2,000 hours or annually—whichever occurs first.
