Tinius Olsen has continuously been receiving request to customize its Super L test frames to handle various sizes and shapes of specimen. Although, the company offers standard options for the lengths of pulling screws and columns, it had received a request for a non-magnetic load frame for the first time in its 133 years of operation.
Need for a Non-Magnetic Load Frame
A division of the Russian Academy of Science is conducting a suite of experiments to explore the correlation between magnetic fields and stress loading. Hence, the use of a loading frame made of steel with a capacity of 60,000 lbf (300 kN) will apparently have a negative impact on any magnetic measurements.
Solution from Tinius Olsen
In order to resolve the aforementioned issue, Tinius Olsen closely worked with the customer for the development of a stiff loading frame featuring aluminum crossheads. The newly developed stiff loading frame enabled the customer to perform its tests without any magnetic interference from the test frame.
The machine with the aluminum crosshead is shown in Figure 1.

Different options of the same machine available are shown in Figure 2, demonstrating the customization available from Tinius Olsen.

The machine next to the first machine in Figure 2 is also a 60,000lbf capacity Super L but is equipped with an adjustable height top crosshead on columns, which have an additional length of 3 ft. with strategically positioned spots for the top crosshead to be anchored.
