Hydraulic Universal Testing Machine Offering Performance for
Stretching Compression and Bending Tests on Various Industrial
Materials
1. Product introduction:
The Servo-Controlled Hydraulic Tension-Compression-Bending Testing
Machine is specifically engineered to conduct tension, compression,
and bending performance tests on both metallic and non-metallic
materials and their components, including rebars, wire ropes,
anchor rods, bolt fasteners, cables, and similar specimens.
This testing system finds extensive application across a broad
spectrum of industries, such as aerospace, petrochemicals, wire and
cable manufacturing, machinery fabrication, plastics and rubber
processing, mining, ceramic and building materials production, and
polymer mechanics. It is also a critical piece of testing equipment
for academic and regulatory institutions, including colleges and
universities, scientific research organizations, technical
supervision authorities, and quality inspection stations.
2. Price advantage:
We have intensified our in-house R&D initiatives and
established a dedicated machining center to independently
manufacture core components. This vertical integration strategy
enables us to cut down intermediate process costs while maintaining
consistent, premium product quality.
Our high-quality equipment delivers far greater long-term cost
savings compared to low-cost, inferior alternatives. By minimizing
equipment failure rates, we not only reduce our customers’
maintenance expenses but also enhance overall equipment operational
efficiency. This exceptional cost-performance ratio translates into
tangible, long-lasting benefits for our customers.
3. Standards:
ISO 6892, ISO 6934 BS4449,ASTM C39,ISO75001, ASTM A370, ASTM E4,
ASTM E8 and BSEN standards.

5.Safety Protection Device:
- When the test force exceeds 3% of the maximum test force, the
overload protection mechanism is activated automatically, and the
oil pump motor shuts down immediately.
- When the piston travels to the upper limit position, the position
limit protection is triggered, and the oil pump motor stops
operation.
- When the crossbeam descends to the preset position, the position
limit protection engages, and the reducer ceases operation.
