The NG-EML Series H is a line of horizontal universal testing machines designed for tensile, proof load, elongation, and breaking force testing of long or difficult-to-handle specimens. The horizontal frame provides the test length and loading access required for wire ropes, cables, chains, rebar, slings, fasteners, structural components, and other full-length metal and industrial components.
Each system is configured around the customer’s application instead of being supplied as a fixed machine. Force capacity, test bed length, crosshead or cylinder stroke, test width, grips, fixtures, guarding, control system, and reporting workflow can be adapted to the specimen geometry, required test method, and facility layout. The series includes electromechanical screw-driven configurations for lower-force long specimens and hydraulic configurations for high-force industrial tensile and breaking load testing.
The NG-EML Series H is suitable for laboratories and production environments that need controlled horizontal loading, repeatable force and displacement measurement, guarded test area operation, and application-specific fixture design. Typical applications include tensile strength determination, proof load testing, breaking force testing, elongation measurement, batch quality control, and certification support for long specimens and assembled components.

The NG-EML Series H is used for horizontal tensile, proof load, elongation, and breaking force testing of long specimens and assembled components. Typical applications include wire rope, cable, chain, rebar, slings, fasteners, and structural products that require extended test length, high-force loading, or application-specific fixtures.
For tensile strength, elongation, and breaking force testing of wire rope, steel strand, fiber rope, nylon rope, cable assemblies, and lifting slings. These applications often require long test space, secure gripping, and protective guarding during specimen failure.
For proof load and tensile testing of anchor chains, hooks, shackles, lifting connectors, fasteners, and related hardware. Custom fixtures can be configured around the specimen shape, loading direction, and required test method.
For testing rebar, stranded wire, long rods, structural bars, building components, and other full-length metal products. The horizontal frame provides the required specimen length and loading access when vertical test frames are not practical.
For production quality control, batch acceptance, certification support, and research testing. Common measurements include tensile strength, proof load, elongation, displacement, breaking force, and deformation behavior under controlled loading.
The NG-EML Series H can be configured to support tensile, proof load, breaking force, and force-verification workflows in accordance with selected ASTM, ISO, EN, and other recognized test standards. Applicable methods depend on the specimen type, force capacity, grips, extensometer setup, calibration requirements, and reporting procedure.
Commonly supported standards include:
A horizontal universal testing machine is used when specimen length, weight, geometry, or expected elongation makes vertical testing impractical. The horizontal layout provides more usable test length, easier specimen handling, and better access for custom grips and fixtures.
Long products such as wire rope, cable, chain, rebar, slings, and assembled hardware can be positioned along the test bed instead of being lifted into a vertical frame. This improves loading access and helps maintain alignment during tensile, proof load, and breaking force testing.
For high-force applications, the horizontal design also supports protective guarding around the test area. This is important when testing specimens that may release stored energy at failure, including ropes, chains, cables, and sling assemblies.
The NG-EML Series H is configured around the specimen type, required force capacity, test length, stroke, fixture design, and safety requirements. The system can be supplied in electromechanical or hydraulic configurations depending on the application.
The horizontal frame supports long specimens and provides stable loading alignment during tensile testing. Test space can be configured according to specimen length, fixture layout, stroke requirements, and available floor space.
The H-205 configuration uses an electromechanical screw-driven system for lower-force long-specimen testing. The H-206 and H-506A configurations use hydraulic loading systems for higher-force tensile, proof load, and breaking force applications.
The system supports closed-loop control of force, displacement, and extension. Load cells, displacement sensors, and extensometer options can be selected according to the required test method and measurement accuracy.
Fixtures are selected according to specimen geometry and loading requirements. Available options may include pin-type grips, wedge grips, rope and cable fixtures, chain fixtures, hook and shackle fixtures, rebar fixtures, and custom tooling for non-standard components.
The system can include protective shielding or a fully enclosed protective frame depending on force capacity and specimen type. Safety functions may include overload protection, travel limits, emergency stop controls, guarded test areas, and protective covers for breaking load tests.

Configuration Note: Each NG-EML Series H system should be specified based on specimen type, maximum force, required test length, expected elongation, grip design, safety requirements, and facility constraints.
The NG-EML Series H can be supplied with a closed-loop control system for force, displacement, and extension measurement. The control package is selected according to the machine configuration, required capacity, sensor package, and test method.
The software supports programmable test procedures, real-time display of force and displacement data, live graphing, custom report formats, and result calculations for tensile strength, proof stress, yield behavior, elongation, modulus, and breaking force. For production or laboratory workflows, reports and test data can be configured for export and review based on the customer’s documentation requirements.
Core functions include:
The NG-EML Series H is a line of horizontal universal testing machines engineered for tensile, breaking load, and elongation testing of long or rigid specimens that cannot be mounted vertically. Applications include wire rope, round-link chain, slings, cargo straps, rebar, rods, fasteners, and structural cable assemblies. The horizontal orientation allows specimens up to 5000 mm in length to be gripped and pulled without requiring a high-clearance test area. Three configurations cover force capacities from 200 kN to 5000 kN, making the Series H suitable for everything from laboratory-scale wire testing to heavy industrial proof-load applications. Contact us to discuss which configuration fits your requirements.
The Series H is offered in three configurations. The H-205 is a 200 kN electromechanical model suited for lighter wire, strand, and fastener testing with precise speed control down to 0.001 mm/min. The H-206 scales to 2000 kN using a servo-hydraulic drive for chain, sling, and heavy structural cable testing with specimen lengths up to 3000 mm. The H-506A reaches 5000 kN with a hydraulic cylinder spanning specimen lengths from 600 mm to 5000 mm, covering full-length proof-load testing of large crane ropes and bridge cables. All three models share the same Accuracy Class 1 measurement chain and 1/500,000 FS force resolution. Request a quote for the configuration that matches your capacity and specimen range.
The NG-EML Series H meets Accuracy Class 1 per ISO 7500-1 and ASTM E4, which sets maximum permissible error at ±1% of the indicated force from 2% to 100% of load cell capacity. Tensile test procedures for metals are covered by ASTM E8/E8M and ISO 6892-1. Wire rope breaking load and elongation tests follow ISO 3108 and ASTM A931. Reinforcing steel testing conforms to ASTM A370 and ISO 15630-1. Chain and sling tests align with relevant EN and ISO chain-load standards. The calibration system supports traceable verification of the force channel, crosshead displacement, and extensometer channels. Contact our team to confirm standards coverage for your specific application.
The horizontal design accommodates long or rigid specimens that standard vertical frames cannot hold. The H-205 handles specimens up to approximately 3000 mm; the H-206 also reaches 3000 mm; and the H-506A spans 600 mm to 5000 mm, covering full-length rope assemblies with swaged end fittings. The machine accepts round wire, stranded rope, bar, chain links, rebar, structural rod, flat strap, and bolt assemblies through interchangeable grip sets. Grip jaw inserts are matched to specimen cross-section and surface profile to minimize stress concentrations at the grip interface. Contact us about the complete grip accessory list or custom gripping solutions for your specimen type.
Force measurement meets Accuracy Class 1 per ISO 7500-1 and ASTM E4, with a maximum permissible error of ±1% of the indicated value from 2% to 100% of load cell capacity. Force resolution is 1/500,000 of the full-scale load cell range, so on a 200 kN system each displayed digit represents 0.4 N. The measurement chain - load cell, amplifier, and analog-to-digital converter - is verified together during calibration rather than component by component, ensuring the complete system accuracy statement applies to recorded test data. Calibration certificates traceable to national standards are supplied with each machine. Contact us to learn more about calibration services and recertification intervals.
Speed range depends on the drive system. The H-205 electromechanical model delivers crosshead speeds from 0.001 mm/min to 500 mm/min, providing the fine control required for strain-rate-sensitive tensile tests per ASTM E8/E8M and ISO 6892-1 Method A or B. The H-206 and H-506A hydraulic models cover the speeds required for breaking-load and proof-load tests on rope, chain, and structural components, where consistent stroke rate matters more than ultra-low speeds. Crosshead position is controlled by servo-valve on the hydraulic models and by servo-motor and ballscrew on the electromechanical model. Request a quote with your target test speeds specified.
The Series H includes a PC-based control and reporting software package that provides real-time force and displacement graphing, user-defined test methods, automatic limit detection for break, peak, and yield, and report generation in PDF or Excel format. Standards-based test templates for ASTM E8, ISO 6892-1, ASTM A931, and ASTM A370 are included. Extensometer channels can be added for percent elongation measurement. Data export formats include CSV and direct database integration. User access levels can be configured to protect calibrated test methods from unauthorized changes in quality-controlled environments. Contact us to discuss software customization or integration with your laboratory information management system.
Yes. Elongation can be measured using crosshead displacement after grip-slip correction, or with a clip-on or laser extensometer attached to a marked gauge length on the specimen. For wire rope, the relevant standard is ISO 3108, which specifies elongation at specified load fractions rather than fracture elongation. The control software supports load-referenced elongation calculations, allowing you to report extension at 10%, 20%, and 50% of breaking load on the same test run. For bar and rod specimens, a clip-on extensometer to ASTM E8/E8M gauge-length requirements can be fitted directly on the horizontal specimen without repositioning the machine. Contact us for extensometer options.
Wire rope end terminations are typically tested with the rope's own swaged or spelter sockets seated in clevis-pin jaw adapters on each crosshead. For rope without end fittings, we offer hydraulic rope grips that distribute the clamping force over a tapered wedge bore, preventing bird-caging and grip-induced failures. Parallel-jaw grips with serrated inserts are used for bar, rebar, and round rod. Flat grips with roughened faces handle strap and webbing slings. All grip adapters mount to a common T-slot crosshead interface, so changeover is done without tools. Request a quote to specify your specimen ends and we will confirm the appropriate grip set.
Vertical frames impose a practical height limit of roughly 3 to 4 metres due to ceiling clearance, specimen handling, and safety considerations when a heavy specimen is suspended at height. A horizontal machine eliminates the height constraint entirely - specimens sit on a low roller table beside the machine bed and are fed in at waist height, making rigging straightforward and reducing handling risk. This is particularly important for crane rope assemblies, offshore mooring chain, and reinforcing bar supplied in straight lengths. The specimen weight is supported along its length rather than hanging from one end, which also eliminates any sag-induced pre-load at the start of the test. Contact us to learn more about our horizontal testing configurations.
The Series H incorporates several layers of protection. Hardware limit switches on the crosshead travel stop motion before mechanical end stops are reached. Force and displacement overload limits in software trigger an emergency stop and hold the crosshead position. A physical emergency stop button is positioned on the front panel and on the handheld pendant. The hydraulic models include a pressure-relief valve set to the system's rated operating pressure and a dual-circuit fail-safe valve that cuts hydraulic pressure on power loss. All rotating and moving components are guarded. The machine frame is rated beyond the maximum test force to provide a safety margin against specimen overload events. Contact us for a full safety specification sheet.
The Series H serves manufacturers and testing laboratories in industries where long tensile members are critical to safety. Crane and hoist manufacturers use it for wire rope breaking-load certification. Marine and offshore industries test mooring chain and deck hardware. Construction quality labs verify rebar tensile properties and elongation for structural compliance. Fastener and anchor manufacturers test threaded rod and bolt assemblies in full-length configurations. Sling and rigging equipment manufacturers certify working load limits. Transport and logistics sectors test cargo lashing strap and tie-down assemblies. The 200 kN to 5000 kN capacity range means a single platform can serve both incoming material inspection and design-validation testing. Request a quote for your industry application.
The Series H arrives as a factory-assembled frame with the drive unit, load cell, and control cabinet integrated. Installation requires a level concrete floor rated for the machine's operating weight and a dedicated electrical supply matching the machine's voltage and current draw. Our service engineers perform on-site installation, which includes mechanical leveling, hydraulic fluid filling (for H-206 and H-506A), electrical connection, and initial software configuration. Calibration to ISO 7500-1 / ASTM E4 using certified reference force transducers is completed during commissioning. Operator training covers machine operation, test method setup, and routine maintenance. Contact us to schedule installation and commissioning for your facility.
Routine maintenance is straightforward and described in the supplied maintenance manual. The electromechanical H-205 requires periodic lubrication of the ballscrew and linear guides and inspection of the drive belt. The hydraulic H-206 and H-506A require hydraulic fluid level checks and filter replacement intervals defined by operating hours. The load cell and force measurement chain should be recalibrated annually or after any overload event. Grip jaw inserts and wedge-face elements wear with use and are available as replacement parts from our service team. We offer preventive maintenance contracts that include scheduled visits, calibration, and consumable replacement. Contact us to set up a service agreement.
Yes. Proof-load testing - applying a defined load and holding it for a specified time to verify structural integrity without fracture - is a standard application for the H-506A 5000 kN model in particular. The control software supports load-hold sequences where the crosshead moves to a target force, switches to force-control mode, and maintains the load within a tight tolerance for the required dwell period. Pass/fail criteria, hold time, and acceptable force drift limits are configured in the test method. A timestamped record of the load profile is saved automatically and can be exported as a calibrated proof-load certificate. Contact us to discuss proof-load test requirements for your product type.
A vertical UTM is the standard choice for short, rigid specimens where height is not a constraint. The NG-EML Series H is the better choice when specimens exceed roughly 1.5 metres, when specimens are heavy enough that vertical suspension creates handling risk, or when the specimen geometry requires both ends to be at the same elevation - such as chain links that must remain in their natural orientation. For metallic wire and rod that can be tested at standard gauge lengths, a vertical UTM is equally suitable and typically occupies less floor space. We recommend the horizontal configuration specifically when specimen length or loading geometry drives the decision. Contact us to discuss which configuration best fits your test program.
Yes. Chain testing is one of the primary applications for the Series H. The H-206 (2000 kN) and H-506A (5000 kN) models handle round-link chain used in lifting, anchoring, and mooring applications. Chain end links seat directly into clevis-pin jaw adapters on each crosshead, maintaining the natural link orientation and preventing stress concentration at the test interface. Test parameters for proof load, breaking load, and elongation follow EN 818 series, ISO 1834, and relevant DNV or ABS chain type approval requirements. The control and reporting software records peak force, elongation, and hold-time data for each chain test and generates the documentation needed for type approval submissions. Request a quote for chain testing configuration details.
Electrical supply requirements depend on the model and regional specification. The H-205 electromechanical model typically operates on a three-phase 400 V / 50 Hz or 480 V / 60 Hz supply, with the servo drive and motion controller drawing combined peak power during fast ramp-up cycles. The H-206 and H-506A hydraulic models power a hydraulic pump motor that represents the main electrical load, rated for the machine's hydraulic system pressure and flow requirements. Exact current ratings, circuit breaker sizing, and cable cross-section recommendations are provided in the installation manual supplied before delivery. Contact us to confirm electrical requirements for your facility layout.
Force resolution is 1/500,000 of the full-scale load cell range across all three Series H models. On the H-205 with a 200 kN load cell, each incremental display step equals 0.4 N. On the H-506A with a 5000 kN cell, each step equals 10 N. This resolution exceeds the Accuracy Class 1 requirement of ISO 7500-1, which demands repeatability and error within ±1% of indicated force. The high resolution is particularly useful when measuring yield load transitions and when running tests that require precise load-hold control at a fraction of the system's full-scale capacity. Contact us to discuss load cell range selection for your specimen population.
Yes. The H-205 electromechanical model supports a secondary low-range load cell mounted in series or as a swap-in option, allowing tests at 2% to 100% of the secondary cell's range with the accuracy class maintained. This is useful when a laboratory runs both fine-wire specimens (low kN range) and structural cable specimens (full 200 kN range) on the same machine. The control software manages the active load cell channel and applies the correct calibration polynomial for each range. Load cell swap is performed via a quick-release connector and bracket system that does not require recalibration of the machine frame or crosshead. Contact us to configure a dual-range system for your application.
Available options may include laser extensometers for non-contact elongation measurement, roller conveyors for specimen support along the machine bed, customized grip sets for specialized end terminations, and application-specific data acquisition options suited to your measurement requirements. Environmental conditioning can be integrated for testing at controlled temperatures when the specimen length fits within the chamber's working depth. Remote-access monitoring allows test status viewing from outside the test area during high-energy break tests, which is useful when safety separation from the machine is required during destructive testing. Customization scope depends on the machine model and application. Contact us to discuss which options are available for your testing program.
The machine bed has a fixed crosshead at one end and a moving crosshead driven by the test actuator at the other. The distance between grip faces when the crosshead is at its home position defines the maximum specimen length for that model. On the H-506A, the jaw-to-jaw span adjusts from 600 mm to 5000 mm by positioning the moving crosshead along the machine bed before the test begins. For specimens shorter than the minimum span, spacer blocks or reduced-length grip assemblies close the gap. The specimen is loaded into the grips while the machine is in force-control mode at near-zero preload, then the test sequence initiates the ramp to target force or displacement. Contact us to confirm compatibility with your specimen length distribution.
Each machine ships with an operator manual covering machine setup, specimen loading, test method configuration, and routine maintenance. An installation manual details floor loading, electrical connection, and commissioning steps. A calibration certificate traceable to national metrology standards documents the force measurement accuracy at commissioning. The control and reporting software package includes a help file and template library. CE Declaration of Conformity and relevant safety certificates are included for EU-destined machines. On request, a material certificate for the load cell and structural weld inspection records can be provided. Contact us for a full documentation package list before purchase.
The Series H is designed primarily for quasi-static tensile, breaking-load, and proof-load testing rather than high-cycle fatigue. The electromechanical H-205 can perform limited cyclic sequences - such as the load/unload cycles in preload conditioning - at the speeds achievable with its ballscrew drive. For true fatigue testing with sinusoidal waveforms at frequencies above 1 Hz, a dedicated servo-hydraulic fatigue frame with dynamic-rated load cells and actuator seals is the appropriate solution. If your test program includes both static tensile and low-cycle fatigue work, contact us and we can recommend the right combination of equipment. Request a consultation to discuss your full test requirements.
The NG-EML Series H is covered by our standard warranty on materials and workmanship, with service support provided through our technical team. Warranty terms, duration, and exclusions are detailed in the sales agreement and vary by region. Our service network offers post-warranty calibration, preventive maintenance contracts, and spare parts supply to keep the machine operating within its rated accuracy class throughout its service life. We recommend scheduling the first post-warranty calibration check at the one-year mark to maintain traceability documentation required by most quality management systems. Contact us for warranty details and service contract options for your location.
