A testing actuator serves as a flexible testing machine

The electromechanical servo-testing actuators can be universally used as flexible testing machines. They are ideal for tensile tests and compression tests and can be variably integrated in different test fixtures. Applications range from materials and components testing to tests performed on end products. In addition, they can be used to test production steps (e.g. joining, press-fitting and assembly) or to perform fatigue tests with large strokes.

Conveyor belt testing

The fatigue life of conveyor belts is tested using dynamic pull-out tests.

For the test, a 10 kN electromechanical servo-testing actuator was mounted on a two-column load frame.

Advantages & Features

Description

The electromechanical servo testing actuator is available in six versions: 1, 2, 5, 10, 20 and 30 kN.
High test speeds up to 30 m/min guarantee high efficiency.
Operating modes—force control and position control—can be switched seamlessly.
A large range of standard modules such as load cells, test fixtures, testing software, and testControl standard electronics is available for various testing situations.
Accessory cards and interfaces are available for easy integration in production lines.

Advantages & Features

Advantages and features

Flexible usage:

Variable mounting via front or rear flange or via trunion mount
measurement and control electronics testControl II in seperate casing and therewith optional positionable (Optional in IP54 casing)

Testing actuator in use as a portal testing machine

Portal solutions with electromechanical testing actuators

The portals have a modular construction, which allows them to be configured easily for testing requirements. The T-slotted base platform, portal, and electromechanical servo testing actuator are all available in various sizes and shapes. The position of the testing actuator in the X-, Y-, and Z-axis can be adjusted manually or via an electric motor.
