Overview
The TOFENG WAL-500 Computer-Controlled Horizontal Tensile Testing Machine is an industrial-grade electromechanical system engineered for high-capacity, long-stroke tensile evaluation of structural and load-bearing components. Designed specifically for horizontal loading configuration, it eliminates gravitational interference and accommodates full-scale, as-manufactured specimens—such as marine-grade anchor chains, aerospace-grade cables, high-tensile steel ropes, lifting slings, and large-diameter bolts—that exceed the dimensional limits of conventional vertical testers. Its core architecture employs a rigid welded steel frame, a single-rod double-acting servo-controlled hydraulic actuator, and high-fidelity load measurement via precision compression-tension load cells compliant with ISO 376 Class 1 accuracy requirements. The system operates on a closed-loop control principle, enabling precise regulation of force, displacement, and strain rates per ASTM E4, ASTM E8/E8M, ISO 6892-1, and EN 10002-1 test standards.
Key Features
- Horizontal configuration optimized for testing elongated, high-inertia specimens up to 25 meters in effective gauge length—ideal for certification of marine mooring systems, power transmission conductors, and civil engineering tendons.
- Robust welded frame structure with modular movable crosshead, adjusted hydraulically and secured via mechanical pin-locking—ensuring repeatable alignment and minimal parasitic bending moments during loading.
- Double-acting servo-hydraulic actuator (1000 mm stroke standard, customizable) delivering smooth, low-noise force application with dynamic response suitable for quasi-static and creep testing protocols.
- High-resolution displacement feedback via optical encoder (0.0001 mm resolution) synchronized with real-time load acquisition at ≥1 kHz sampling rate.
- Integrated digital servo amplifier supporting simultaneous force, displacement, and strain control loops—enabling multi-stage loading profiles, load holding, and automatic rupture detection with emergency stop activation.
- Separate control console with ergonomic layout and integrated safety interlocks; full machine enclosure with polycarbonate safety shields meeting ISO 13857 clearance requirements.
Sample Compatibility & Compliance
The WAL-500 accommodates a broad spectrum of high-strength metallic and synthetic load-bearing elements—including galvanized steel wire ropes (≥6×37 IWRC), stud-link anchor chains (R3/R4 grade), polyester/dyneema lifting slings, prestressed concrete tendons, and heavy-duty clevises and shackles. Specimen gripping is facilitated by custom-engineered wedge-action or hydraulic self-tightening fixtures, ensuring uniform stress distribution and minimizing slippage artifacts. All force calibration procedures adhere to ISO/IEC 17025-accredited practices, with traceability to NIM (National Institute of Metrology, China) and optional UKAS-certified verification. System software supports audit-ready data logs compliant with FDA 21 CFR Part 11 and GLP/GMP documentation requirements, including electronic signatures, version-controlled test methods, and immutable raw-data archiving.
Software & Data Management
TOFENG’s proprietary TensileMaster™ v4.2 software provides intuitive test setup, real-time visualization of multiple concurrent curves (force–displacement, force–time, stress–strain, and derivative modulus plots), and automated calculation of key mechanical parameters—including ultimate tensile strength (UTS), yield strength (0.2% offset), elongation at break, reduction in area, and proof load verification. Raw data exports are available in CSV, XML, and ASTM E1432-compliant .tdms formats. The platform supports user-defined test templates aligned with ISO 15630-1 (reinforcing steels), ISO 17893 (chains), and DNVGL-ST-0378 (offshore lifting equipment). Audit trails record all operator actions, parameter changes, and calibration events with time-stamped metadata.
Applications
- Qualification testing of marine mooring systems under DNV-RP-F205 and API RP 2SK guidelines.
- Mechanical validation of overhead ground wires and ACSR conductors per IEEE 1138 and IEC 61395.
- Certification of lifting gear per EN 13414-1, ASME B30.9, and LEEA standards.
- R&D evaluation of advanced high-strength alloys, composite tendons, and cold-formed fasteners.
- Factory acceptance testing (FAT) and third-party inspection for infrastructure projects involving bridge stay cables and seismic dampers.
FAQ
What is the maximum specimen length supported without extender frames?
The standard effective test length is 25 meters between grips; optional extended frames support up to 50 meters upon request.
Does the system support strain-controlled testing with extensometers?
Yes—compatible with clip-on and non-contact video extensometers (e.g., DIC systems) via analog/digital I/O interface.
Is remote diagnostics and firmware update capability available?
Yes—the embedded controller supports secure SSH-based remote access and over-the-air updates through enterprise IT networks.
Can test reports be generated in bilingual (English/Chinese) format?
Yes—report templates are fully customizable and support multi-language export with configurable headers, footers, and compliance statements.
What is the typical lead time for factory calibration and commissioning?
Standard lead time is 6–8 weeks post-order confirmation, including on-site installation, mechanical alignment verification, and performance qualification per ISO 7500-1 Class 1.
