Tuofeng WAL-2000 Computer-Controlled Horizontal Tensile Testing Machine

Overview

The Tuofeng WAL-2000 Computer-Controlled Horizontal Tensile Testing Machine is a heavy-duty electromechanical testing system engineered for high-capacity static tensile evaluation of structural and safety-critical components. Designed around a rigid horizontal frame architecture with a single-rod, double-acting servo hydraulic actuator, the system delivers precise, repeatable force application up to 2000 kN—suitable for full-scale qualification of wire ropes, marine anchor chains, lifting slings, safety harnesses, high-strength bolts, shackles, and other load-bearing hardware. Unlike vertical tensile testers, its horizontal orientation eliminates gravitational interference during specimen elongation and enables stable alignment of long, flexible, or high-aspect-ratio specimens (e.g., multi-meter cable assemblies). Force is measured via high-stability compression-tension load cells compliant with ISO 376 Class 0.5 accuracy requirements, while displacement is tracked using optical rotary encoders with 0.1 µm resolution. The machine operates under closed-loop control of force, displacement, and strain—enabling ASTM E8/E21, ISO 6892-1, and EN 10002-1 compliant test protocols.

Key Features

• Rigid welded steel frame with reinforced base anchoring—designed for 2000 kN ultimate load without frame deflection or resonance
• Single-rod, double-acting servo-controlled hydraulic cylinder with integrated position feedback and pressure-compensated flow regulation
• High-precision bidirectional load cell (±0.5% FS accuracy, temperature-compensated, 10,000 Hz sampling rate)
• Adjustable test length range from 2 m to 25 m (excluding piston stroke), configured via hydraulically actuated movable crosshead and mechanical pin-lock positioning
• Dual-mode displacement measurement: high-resolution encoder on actuator shaft + optional extensometer interface for local strain monitoring
• Integrated safety architecture including emergency stop circuitry, physical guarding, interlocked access doors, and automatic rupture detection with dynamic unloading
• Modular fixture interface compatible with custom-designed grips—including wedge-type rope clamps, threaded bolt adapters, and clevis-pin configurations

Sample Compatibility & Compliance

The WAL-2000 accommodates specimens ranging from 3 mm diameter stainless steel cables to 80 mm diameter mooring chains, with tensile lengths exceeding 20 meters. Its modular grip system supports standardized test geometries per ASTM A1023 (wire rope), ISO 17079 (marine chain), and EN 12195-2 (lashing equipment). All force and displacement data acquisition complies with ISO/IEC 17025 traceability requirements when calibrated against NIST-traceable standards. System software maintains full audit trail functionality aligned with FDA 21 CFR Part 11 and GLP/GMP documentation standards—including user authentication, electronic signatures, and immutable raw data archiving.

Software & Data Management

Control and analysis are performed via Tuofeng’s proprietary TestMaster v5.2 software platform, running on an industrial-grade Windows OS controller. The software implements three independent closed-loop control modes (force, displacement, and strain rate), with programmable ramp-hold sequences, multi-step loading profiles, and real-time PID parameter tuning. It automatically calculates and reports key mechanical properties—including ultimate tensile strength (UTS), yield strength (0.2% offset), elongation at break, modulus of elasticity, and reduction in area—according to selected international test methods. All test curves (F–δ, F–t, σ–ε) are exportable in CSV, XML, and PDF formats. Raw data files include embedded metadata: operator ID, calibration certificate ID, environmental conditions (optional sensor input), and timestamped event logs.

Applications

• Qualification testing of offshore mooring systems and deep-sea anchor chains per DNV-RP-F105 and API RP 2SK
• Proof and break testing of personal protective equipment (PPE) such as fall arrest lanyards and harness webbing per EN 361 and ANSI Z359.1
• Mechanical validation of aerospace fasteners, landing gear components, and composite tow cables
• Research-grade tensile characterization of high-strength alloys, fiber-reinforced polymers, and braided synthetic ropes
• Factory acceptance testing (FAT) and third-party certification for lifting gear manufacturers seeking CE, ABS, LR, or BV type approval

FAQ

What is the maximum specimen length supported without extension frames?
The standard test envelope accommodates specimens from 2 m to 25 m in gauge length, excluding the 1000 mm piston stroke. Custom-length configurations up to 50 m are available upon request.
Does the system support strain-controlled testing with extensometry?
Yes—the machine provides analog and digital interfaces for clip-on or non-contact extensometers (e.g., video-based DIC systems), enabling true engineering strain measurement per ISO 527-1 and ASTM D638.
Is the software compliant with regulatory data integrity requirements?
TestMaster v5.2 includes full 21 CFR Part 11 compliance features: role-based access control, electronic signatures, audit trails with immutable timestamps, and secure data encryption.
Can the WAL-2000 be integrated into an automated production line?
Yes—via Ethernet/IP or Modbus TCP communication protocols, the controller supports PLC handshaking, barcode-triggered test initiation, and MES-level data upload.
What maintenance intervals are recommended for hydraulic and control subsystems?
Hydraulic oil and filter replacement every 2,000 operating hours; load cell recalibration annually or after 10,000 cycles; encoder alignment verification quarterly. Full service manuals and OEM spare parts kits are provided.
