Hydraulic Universal Testing Machine Featuring Cylinder Lower Type Main Machine for Tensile and Compression Testing of Materials

This hydraulic universal testing machine features a cylinder lower type main machine designed for tensile and compression testing of materials. Developed primarily for conducting tensile tests on prestressed concrete steel strands and compression tests on metallic and non-metallic materials, it accurately measures critical indicators including maximum force, yield force, and modulus of elasticity in full compliance with ISO 6934-4.

Extensively applied across industries including metallurgy, construction, light industry, aviation, aerospace, materials research, higher education institutions, and scientific research institutes. The entire test operation process and data processing procedures fully satisfy specifications outlined in GB/T 228.1-2010 and GB/T 5224-2014 standards.

• Intensified investment in independent research and development with dedicated processing center
• Core components manufactured in-house to reduce intermediate costs while maintaining consistent quality
• High-performance products delivering superior long-term value compared to low-quality alternatives
• Minimized machine failure rate to lower maintenance expenses and enhance operational efficiency

Hydraulic cylinder mounted at the bottom of the load frame with tensile testing space arranged at the upper part, while compression and bending testing spaces are situated between the lower crosshead and worktable.

Hydraulic power drives the piston inside the cylinder to supply required loading force. The lower crosshead is driven by an electric motor through reducer, chain drive mechanism, and screw pair, achieving flexible and accurate adjustment of testing space.

Designed for Windows operating system with dedicated test software incorporating programmable control capabilities. Supports arbitrary combination of multiple test modes including constant rate test force control, constant rate displacement control, test force retention, and displacement retention.

Control commands transmitted from computer to servo valve adjust opening magnitude and flow direction, precisely regulating hydraulic oil flow into the oil cylinder for accurate control over constant test force speed and constant displacement speed.

Complete file operation functions enable test reports, test parameters, and system parameters to be stored and managed in standardized file formats. Hierarchical user permission management with fully configurable system parameters ensures operational flexibility and stable reliability.

ISO 6892, ISO 6934, BS4449, ASTM C39, ISO75001, ASTM A370, ASTM E4, ASTM E8, and BSEN standards.
