H. 5 – DYNAMIC HYDRAULIC TESTING MACHINES UP TO 2500 KN – 01 SERIES
Dynamic hydraulic testing machines of H. 5 type and series 01 in design up to 2500 kN with servo cylinder in the crossbar are designed for low and high cycle fatigue tests, fracture toughness, crack propagation, etc. This series of machines is characterized by high frame rigidity and mechanical resistance . The range of a given machine depends on the dynamic stroke and frequency. A specific test set is derived from these parameters, which consists of a test frame, a servo-hydraulic cylinder and a hydraulic unit.

Basic set of a dynamic testing machine
Focus on these 3 basic machine parts…
Machine frame – hydraulic servo cylinders – edge coaxiality corrections
Machine frame
First of all, consider what you want to try. Based on this consideration, select the machine frame – series 00 or series 01.
If you have a high frequency of adjustment of the working space, then complete the machine with an automatic electro-hydraulic transfer and clamping of the crossbar.
Hydraulic servo-cylinder
For the H.5 series 00, a maximum piston rod stroke height of 100 mm is recommended. It also depends on which HA you chose from the previous table and whether you use a classic dynamic sealing ring or a hydrostatic piston rod guide for higher lateral loads on the servo cylinder.
Coaxiality
Do you want to be sure? Use the BENTROD measuring and setting unit designed for evaluation and optimization of concetricity and edge coaxiality correction according to ASTM E1012, GES400 (NADCAP), GE450 and ISOTC 164SC5WG11
Selection of hydraulic unit including diagnostics
Hydraulic Unit (HA) selection
HA is designed as a compact hydraulic pressure unit designed for fatigue tests with water or air cooling.
HA equipped with HALT 18 – Diagnostic SIEMENS control system with system monitoring of conditions, pressures and service intervals via touch LCD.
Noise
The possibility of covering HA is made by a special anti-noise cover PAC <72 dB. Easy access from all sides using quick couplings allows easy handling around the HA (filter change, oil change, etc.). Thanks to the silent block suspension, the HA can be placed directly on the test room floor.
Hydraulic connection
The connection between the HAD hydraulic unit and the machine frame is made using the VOSSFORM system, including the pressure test. Oil stains and gutters have no chance.
Appropriate selection of control unit and test software, including modules
Measuring and control electronics
EDCi Control electronics with synchronization of all measuring and control channels in real time with a sampling frequency of 10kHz.
Choose the RMCi7 or RMCi8 series remote control with OLED display integrated CENTRAL STOP.
Basic parameters of electronics
Analog signal resolution level ± 250,000 divisions (20 ms). Internal frequency 64 bit, data acquisition 32 bit, AD 24 bit, arithmetic, sampling frequency 10kHz. Integrated RS232 for VIDEO extensometers. PC connection – Ethernet 10/100 Mbit, USB 2.0.
Machine control and testing evaluation
Test & Motion + software – DYNPACK – intuitive software for long-term dynamic tests that you will fall in love with. All you have to do is choose the test modules according to the given test standards and you can test the samples.

Test&Motion+ – DYNPACK Software
Intuitive software for long-term dynamic tests…
Test & Motion + – DYNPACK – intelligent, intuitive and powerful software that will help you increase productivity and testing quality in your test rooms and testing laboratories. You can streamline, refine, and accelerate your testing and adapt your testing environment to make it easy for operators to measure the mechanical properties of materials in a dynamic single-axis or multi-axis test mode with support for EN, ISO, DIN, ASTM, and GOST standards.
BENTROD System
A solution that can precisely and easily set the coaxiality of a dynamic system
LABORTECH H.5 series test load frames exhibit excellent rigidity and coaxiality, which minimizes bending stress to increase test accuracy and reduce data scatter. Proper alignment prevents off-axis bending stress, which can degrade the sample (sampling and production is very expensive) or the resulting data will be skewed and therefore unusable. BENTROD measuring and setting unit designed for evaluation and optimization of concentric and edge correction of coaxiality (clamping) of clamping grips for static and dynamic testing machines according to ASTM E1012, GES400 (NADCAP), GE450 and ISOTC 164SC5WG11.
