Servo-Hydraulic Universal Testing Machine Series D

RoboTest Series D servo-hydraulic universal testing machine is designed with up-mounted actuator structure. Bidirectional differential cylinder provides bidirectional control of tension and compression in one single space.  

Clearance-free structure and actuator up and down to adjust the test space offers easy operation and high efficiency. This machine is mainly used for tensile test of metallic materials. It provides closed loop control of constant force, constant displacement and constant extension, smoothly switching among them.

Test results can be automatically calculated and be able to printed and exported.  

Load Frame Configuration: 2/4 columns, servo-controlled hydraulic

Capacity:  600kN, 1000kN, 2000kN

Test Space:  Single zone

Typical specimens:  Fasteners, rebar, chain, welds, castings
