This series consists of high-rigidity, single-space electro-hydraulic servo universal testing machines developed and manufactured by Zhejiang Yiyu Instrument Equipment Co., Ltd. With a load capacity ranging from 100kN to 1000kN, these machines are specifically designed for high-load mechanical performance testing in sectors such as steel structures and civil engineering, offering exceptional stability and testing accuracy.
Core Design and Technical Highlights
- High-Rigidity Six-Column Structure: The main unit features a six-column frame design, incorporating external-cylinder grips and an open-jaw structure. This design ensures equipment rigidity during high-load testing while greatly simplifying the specimen clamping process.
- Efficient Single-Space Operation: The single-space design allows tensile, compression, and bending tests to be performed within the same area; the testing space is easily adjusted by raising or lowering the piston.
- Precision Control System: Utilizing computer-controlled electro-hydraulic servo technology, the system enables precise closed-loop control of key parameters such as test force and displacement.
- Independent Intelligent Console: Equipped with a floor-standing independent control cabinet (dimensions: 600x650x1400mm) featuring a large industrial display screen, allowing operators to monitor test curves and data in real-time.
Key Functions and Application Areas
This series serves as a multifunctional material testing platform capable of meeting diverse mechanical performance testing requirements:
- Tensile Testing: Suitable for metal rods, plates, rebar, steel strands, high-strength bolts, fasteners, pipes, and various high-hardness metal materials.
- Bending Testing: Used for analyzing the bending properties of metal materials, with a maximum support span of 300mm.
- Compression Testing: Supports compressive strength testing for construction materials such as concrete.

Frequently Asked Questions (FAQ)
Q1: What are the advantages of this machine's "single-space" design?
A: A single-space design means that all tests (tensile, compression, and bending) are performed within the same testing zone. This eliminates the hassle of moving heavy specimens between different testing zones and significantly improves testing efficiency for large specimens.
Q2: Which industry standards does it meet?
A: The equipment is designed to comply with relevant national standards, such as GB/T 2611 (General technical requirements for testing machines), GB/T 16826 (Electro-hydraulic servo universal testing machines), and GB/T 228.1 (Tensile testing of metallic materials).
Q3: What are the laboratory environment requirements for installation?
A: The equipment requires a 380V AC three-phase power supply with a total power rating of 1.5 kW. Due to the substantial weight of the main unit (ranging from 1.1 to 2.1 tons), installation on a solid, level floor is recommended.
Q4: Why does the equipment feature a six-column structure and an externally mounted cylinder?
A: The six-column structure provides exceptional frame rigidity, ensuring measurement accuracy under high loads; the externally mounted cylinder design facilitates easier maintenance and creates a more open space around the grips, making specimen loading and unloading more convenient.
Q5: Is measurement accuracy guaranteed?
A: Yes. The equipment achieves an accuracy class of Class 1, with an effective measurement range of 4%–100% of full scale (F.S.). The relative error of the indicated value is strictly controlled to within ±1%, ensuring the reliability and authority of the test data.
