One Strong Post

PSL made a specialized post for geosciences research at the Homestake Mine in Lead, South Dakota. UW-Madison Geology graduate student JoAnn Gage, wrote a summary of the experiment, which used the post.

“We are examining how the material properties of rock vary over spatial scales. In order to measure deformation in the rock, we needed to apply 100 tons of pressure to the rock mass. We rented a 100-ton hydraulic cylinder and PSL designed and manufactured a steel post with a 100 ton load capacity to our specific height and size requirements. The post was designed to work with the hydraulic cylinder and fit tightly on top to avoid kick-out during loading and increase safety during the experiment.”
