QJDT QJDW311 Horizontal Tensile Testing Machine

Overview

The QJDT QJDW311 Horizontal Tensile Testing Machine is an industrial-grade static tensile testing system engineered for high-capacity mechanical characterization of elongated, flexible structural components. Unlike vertical universal testing machines, its horizontal configuration provides optimal alignment and stability when evaluating specimens subject to significant axial extension—such as marine anchor chains, high-strength steel wire ropes, synthetic fiber cables, mooring lines, and safety harness assemblies. The system operates on the principle of controlled uniaxial tension, applying calibrated load via a servo-hydraulic or electromechanical actuation system (model-dependent), with force feedback governed by high-stability load cells traceable to national metrological standards. Designed for compliance-driven environments—including shipbuilding QA labs, offshore equipment certification bodies, and rope manufacturing R&D centers—the QJDW311 supports full-cycle tensile testing up to 10,000 kN, enabling determination of ultimate tensile strength (UTS), yield strength, elongation at break, modulus of elasticity, and load–extension behavior under quasi-static conditions.

Key Features

• Horizontal loading architecture minimizing gravitational misalignment and bending moments during high-load testing of long, low-stiffness specimens.
• Modular load frame design accommodating custom test lengths—from 3 m to over 30 m—based on specimen geometry and industry-specific gage length requirements.
• High-precision load cell with ±0.01% full-scale accuracy, certified to ISO 376 and traceable to CNAS-accredited calibration laboratories.
• Class 1 force measurement performance per ISO 7500-1, validated across the entire 10 kN–10,000 kN operational range.
• Integrated displacement and strain measurement systems with ≤1% accuracy, supporting both extensometer-based and video-based deformation tracking options (optional).
• Windows-based control software with real-time data acquisition at ≥1 kHz sampling rate, synchronized force–displacement–time logging, and configurable test profiles (ramp, hold, cyclic).
• Comprehensive safety interlocks including emergency stop circuitry, overload cut-off, hydraulic pressure monitoring (for hydraulic variants), and physical barrier integration capability.

Sample Compatibility & Compliance

The QJDW311 accommodates specimens with diameters ranging from 4 mm to 160 mm and tensile lengths exceeding 25 m, making it suitable for classification society-certified testing of maritime rigging, mining hoist cables, wind turbine guy wires, and aerospace tether systems. It meets mechanical testing requirements specified in GB/T 228.1–2021 (Metallic Materials – Tensile Testing), ISO 6892-1:2019, ASTM E8/E21 (Tension Testing of Metallic Materials), and JIS Z 2241. Optional accessories include wedge-type grips for wire rope termination, swivel load pins for torsion-free loading, and environmental enclosures for elevated-temperature or salt-spray preconditioning per ISO 9223. All test reports generated are audit-ready for GLP/GMP environments and support 21 CFR Part 11-compliant electronic signatures when paired with validated software modules.

Software & Data Management

The embedded test control platform provides ISO/IEC 17025-aligned data integrity features: automatic calibration certificate import, digital audit trail with user-level access control, timestamped parameter locking, and encrypted raw data export in CSV, XML, and universal .tdms formats. Test sequences can be pre-programmed using graphical workflow editors, and pass/fail criteria may be defined against standard thresholds (e.g., minimum breaking force per DNV-RP-F105 or EN 13411-2). Raw data files retain full metadata—including sensor serial numbers, calibration dates, operator ID, and environmental logs—ensuring full traceability for third-party audits or regulatory submissions.

Applications

• Breaking strength verification of galvanized steel wire ropes used in port cranes and offshore lifting operations.
• Qualification testing of synthetic fiber mooring lines per OCIMF Mooring Equipment Guidelines.
• Development and validation of high-modulus polyethylene (HMPE) and aramid-based safety slings for fall protection systems.
• Third-party certification of anchor chain segments per ISO 1704, API RP 2SK, and ABS Rules for Building and Classing Marine Equipment.
• Long-term creep and relaxation studies on pre-stressed cable assemblies under sustained loads (with optional load-hold modules).
