Electro-hydraulic Servo Controlled Long Column Large Space Testing System

The long column large space testing system adopted four adjustable screw loading structure, large welded-steel plate made and floor-mounted working table, and a computer-electro-hydraulic servo controller. The tensile and compression actuator mounted on the adjustable crossbeam, and can be used to doing specimen test for the concrete and construction test such as tensile, compression and bending, for the real or ratio contracted pillar, beam or frame. The large and adjustable space leads to easy and quick installation of the structure or specimen. A very important advantage of this machine is that the specimen and the gage and connections lines fixed on the specimen are not move due to the upper installed actuator. This also ensures the reliability of data collection.
This kind of testing machine can be recognized as both material testing machine and structural testing machine.
