Large capacity electronic universal testing machine

500/600/1000KN

Large capacity electronic universal testing machine is a high-precision mechanical property testing device designed for measuring the tensile, compressive, bending, shearing, peeling, and tearing properties of materials under static load conditions, with a maximum test force capacity of 600/1000KN (equivalent to approximately 60/1000 tons of force).

It is core composed of a servo drive system (AC servo motor + ball screw + reducer), load sensor, displacement/extensometer measurement module, rigid load frame, and intelligent control software. Unlike hydraulic-driven machines, it relies on electronic servo control to achieve stepless adjustment of test speed (typically 0.001–500 mm/min) and precise control of force, displacement, and strain, making it suitable for both low-speed static tests and medium-speed performance evaluations of materials and components.

These models are robust, heavy-duty frames commonly used for testing high-strength metals and alloys, advanced composites, aerospace and automotive structures, bolts, fasteners, and plate steels. Frames are available in load capacities of 400kN, 500Kn, 600KN, 1000KN; and several variations are available to accommodate requirements for both extended travel and extra wide test space.
Load weighing system meets or exceeds the requirements of the following standards: ASTM E4, EN10002-2, BS 1610, DIN 51221, ISO 7500-1.

Hydraulic power unit

Hydraulic power unit for the hydraulic wedge grip, 21Mpa pressure. 

Hydraulic wedge grip

A hydraulic wedge grip is a device that clamps specimens using wedge blocks driven by a hydraulic system. It is widely used in material testing (such as tensile, compression, and fatigue tests) to ensure that the specimens are securely held during testing, preventing slipping or damage.

Core Functions and Features: 
Clamping Principle: Driven by hydraulic pressure to close the wedge blocks, providing a uniform and adjustable clamping force suitable for samples of different thicknesses (such as metal, composite materials, plastics, etc.).
Applicable Scenarios: Compatible with static or dynamic testing, supporting samples such as plates, rods, and wires.

Core Advantages over Hydraulic Universal Testing Machines


Aspect600KN/1000KN Electronic Universal Testing  MachineHydraulic Universal Testing Machine
PrecisionHigh (force accuracy ±0.5% of reading, displacement resolution up to 0.001 mm); stable control of micro-load and   small deformation.Relatively low (force accuracy ±1% of reading); poor control of low load and small displacement due to hydraulic oil compressibility.
Energy ConsumptionLow (servo motor only consumes powe  during operation, no idle energy loss).High (hydraulic pump runs continuously,   consuming large amounts of electricity; oil leakage also causes energy waste).
Operation & MaintenanceNo hydraulic oil, no leakage risk; simple daily maintenance (only regular lubrication of mechanical parts); low noise   (≤60dB).Requires regular oil change, filter replacement, and seal inspection; high noise (≥75dB) from hydraulic pump; oil leakage pollutes the environment.
Speed RegulationStepless speed adjustment over a wide range (0.001–500 mm/min); rapid response to speed changes.Narrow speed range (mostly <100 mm/min); slow speed adjustment and response due to hydraulic system inertia.
AutomationEasy integration with software for automatic test procedures, data analysis, and report generation; supports   remote control and data upload.Limited automation; mostly manual or semi-automatic operation; data recording and analysis rely on additional equipment.
Space & InstallationCompact structure, small footprint; no need for special hydraulic pipeline layout; easy installation and relocation.

Bulky; requires dedicated hydraulic station and pipeline installation; difficult to relocate.
