This testing machine is special designed for tensile test of long chains, lifting straps load, rope, sling, belt, cable and other flexible specimens etc.
It adopts horizontal type structure with servo and computer control and mainly used for the standard load holding and broken test.
This testing machine adopts H-type steel welding frame. The test space can be adjusted through the inserted pin according to the different specimens.
The one-way & double action actuator applies the test force and the load cell measures the test force.
It can realize load, speed (displacement) control such as constant speed testing load, constant speed displacement, holding the testing load, holding the displacement etc.
The users can realize the automatic control and testing process through the intelligently programming system, software under Windows system can realize the collection of testing data and testing curves, monitor display in real time. Data and testing curves can be stored through database management, and also equipped with network system interface.
The load frame consists of cylinder seat, cylinder, piston, moveable crosshead, fixed crosshead and load cell etc. The cylinder seat, H-type steel welding frame, moveable and fixed crossheads forms the bearing frame. On the moveable and fixed crossheads, the tensile attachment base is mounted for connecting the U-type grip. The one-way & double-direction low friction piston cylinder with stroke of 1000mm drives the crosshead movement in the action of hydraulic oil, thus to apply the test force to the specimens. The electro-hydraulic servo system controls the loading speed till the test over.
