Hydraulic Universal Testing Machine
Specifically designed for tensile testing of stranded steel wire and prestressed steel strands, delivering accurate mechanical property results.
Application
This testing machine is specifically developed for mechanical property testing of prestressed steel strands and reinforcing steel bars. The dedicated special clamp joint design guarantees that specimens fracture at the intermediate position during testing, ensuring the measured performance values of steel strands are authentic, valid and fully representative of actual material performance.
For steel bar mechanical performance testing, the upper cross beam of the testing machine is lowered by 50cm, then the reinforcement clamp is firmly locked before initiating the testing procedure.
The measurement and control system adopts a full-digital multi-channel closed-loop architecture, supporting three closed-loop control modes including stress control, strain control and displacement control, with seamless impact-free switching between different control modes. The system can accurately measure core mechanical indicators of steel strands including tensile strength, specified non-proportional extension strength, modulus of elasticity and elongation rate.
Price Advantage
We continuously ramp up in-house R&D investment and have established our own dedicated machining center, enabling fully independent production of all core equipment components. This vertically integrated production model eliminates intermediate link costs while maintaining consistent premium product quality.
Our high-reliability testing equipment delivers far greater long-term cost savings for clients compared to low-cost, substandard devices offered by other suppliers. Lower equipment failure frequency not only cuts down clients' recurring maintenance expenditures, but also boosts continuous operation efficiency of the testers.
Compliance Standards
ISO 6892, ISO 6934 BS4449, ASTM C39, ISO75001, ASTM A370, ASTM E4, ASTM E8 and BSEN standards.
Mainframe Structural Features
- Adopts an optimized ergonomic layout: the fuel tank is mounted beneath the main host, tensile test space is arranged above the main unit, while compression, bending and shearing test spaces are positioned below the host
- Robust four-column, two-lead screw structural design delivering exceptional overall stability
- Integrated monolithic design to achieve ultra-high structural stiffness, effectively resisting micro-deformation under maximum loading
- Middle movable crossbeam with adjustable clearance lead screw-nut mechanism to eliminate transmission clearance
- Professional clearance sealing technology enhancing measurement accuracy and extending hydraulic system service life
Safety Protection Systems
Overload Protection Mechanism: When the applied test force exceeds 2% to 5% of the maximum test force for each measurement range, the system automatically triggers overload protection and stops all testing operations.
Travel Limit Protection Mechanism: When the piston rises to the pre-set upper limit position, the system activates travel protection and shuts down the pump motor automatically.
