Load Frame Structure
Featuring a dual test space with extremely high stiffness; cross-head with built-in gear & worm structure driven by motor can reduce the back-lash for more accurate and repeatable test result. Load capacity is available from 600kN to 3000kN.
1. Compact design with rigid four-column & two-lead screw construction;
2. Dual work-space design. The upper one is for tension test while the lower one is for compression, bending and shearing tests, which is quite convenient for different kinds of tests.
3. No gap is in the load frame.
4. Special grip design: no adjustment is needed in the tensile space for samples with same length.
5. Space-adjustment of multiple-level notched column is suitable for specimen with different lengths.
6. The frames have considered all of the human factor into the design to ensure safety, improve testing efficiency, and reduce operators’ weariness.
7. Cylinder mounted at the bottom of the machine guarantees the working gravity.
8. Test space can be extended according to the length & elongation of specimen and other related test requirements.

Crosshead

The middle cross-head with built-in worm gearing structure is directly driven by motor for upward and downward adjustment. Thus the back-lash is reduced greatly so as to work out a more accurate and repeatable test result. With multi-level cross-head positioning structure, the upper cross-head position can be easily changed along with four chrome-plated notched columns depending on the specimen length. Therefore, tests can be performed at a height appropriate for the operator with the movable lower cross-head. With front open hydraulic wedge grips, it is easier to change inserts and specimen loading.

Hydraulic power pack

1. Variable pressure hydraulic power supply provides pressure on demand, reducing heat, extending oil life and eliminating the need for water cooling.
2. Double control mode, manual control & PC servo control model. For manual control model, hydraulic pack is for manually loading and clamping specimen hydraulically for high efficiency of test. While test data & curves can displayed on PC, manual control mode is especially suitable for the batch broken load tests on the large scale of specimens. For PC servo control mode, all can be controlled & processed by PC automatically. Closed-loop servo control of position, load, stress & strain increases the test efficiency and meets the data consistency between collection and analysis.
3. The pumping units are designed to be located in the lab with lower noise level within 65dBa.
4. The oil pump, as the core heart of the oil source, is the power source of the hydraulic system. MARZOCCHI pumps from Italy and the NACHI pumps from Japan are commonly used. The two oil pumps are high pressure gear pump, with low noise and steady performance.
