The machine pictured below right is from the FA Series – Model TO317E-FA – with a maximum testing capacity of 450,000lbf or 2000kN. This machine is primarily designed for the testing of 4in (100mm) and 6in (150mm) concrete cubes, 100mm and 150mm concrete cylinders.
The Tinius Olsen FA Series of digital compression testers features highly robust frames for exceptional stability when testing concrete cylinders or cubes. These compact testers
are made up of three core pieces: the heavy duty load frame, hydraulic pump, and control and display systems.
The large lower bearing block includes a bellows to prevent leaks caused by dust and debris getting into the loading piston. The other advantage of this large bearing block is that it allows for a wide horizontal entrance opening and plenty of ready access for loading and removing specimens.
This series also includes the rapid change platen system with which operators can quickly and easily change accessories, quickly switching between cylinder, block, cube and beam specimen testing.
The hydraulic pumping system is attached to the loadframe and connected to the piston by a high pressure hydraulic hose. The rate of loading and piston return on test completion is controlled automatically by the controller.
While these machines are ideally positioned to test cubes and cylinders, testing can be taken to another level by adding a flexure testing attachment that will work with the pumping unit in the TO317E-FA frame. After installing a simple manual valve system, you are ready to test the flexural strength of concrete beams, up to 100kN (22,000lbf) maximum load.
