Load the main frame:

LFV

The series of loaders are designed for a wide range of precision dynamic dynamic tests using a rigid two-column construction with high axial and lateral stiffness and an accurate assembly process to ensure that loads are fully applied to the specimen. Generally, the actuator is attached to the upper beam for various application purposes. Further testing machine adoption

T

The groove bottom plate is used to facilitate the installation of various clamps, fixtures, components, specimens, man-made devices and finished products. The actuator provides a high piston speed, the manifold is mounted directly on the actuator to provide the best coupling, and the accumulator and servo valve provide the highest dynamic response and reduce pressure fluctuations. The upper beam can be adjusted, hardened and chromed for easy cleaning and extended service life.


Actuator:

LFV

The series of actuators, as part of the loading frame, are designed with a double output rod structure that produces equal axial tensile and compressive forces with hydrostatic bearings. Hydrostatic bearings have very low friction and can be used for the highest precision control and the longest reliable service life under any test conditions. The actuator has a built-in precision displacement sensor. It can be used for a variety of test applications (from static to dynamic) with excellent fatigue stability, accuracy and repeatability. This actuator is the most advanced form of actuator, all

LFV

Multi-function test systems use this type of actuator.


Load cells: Dynamic test systems require precise fatigue level force sensors for precise force measurement and control. The load cell is fixed to the end of the piston rod of the actuator.


Hydraulic source group: The dynamic performance of the hydraulic servo test system is provided by the flow rate and hydraulic pressure of the hydraulic oil.

LFV

System for less than

50kN

The test machine can be equipped with a built-in hydraulic source supply at the bottom of the test machine. The maximum flow rate is

8l/min

With air

Oil cooling exchanger. For systems that require more flow, an external hydraulic source set can be used, and the maximum flow rate can be reached.

500l/min

Or higher. The hydraulic source set comes with a variety of electronic indicators and system management buttons.

Macbook Charger
