The Past

History of Modern Hydraulics
Click to enlarge
Modern Hydraulics was founded in the mid-1950s by a group of house movers, one of whom was the late Pete Freisen, to build and sell unified jacking machines.
The design was mechanically very unsophisticated, so they hired a young engineer from England, my Father, Robin Renshaw. He was able to redesign the unified machine into what we know it as today, and he designed the first crib jacks.

The owners of the company had envisioned many sales and lots of income and were disappointed when this didn't happen. By the late 1950s control of the designs and manufacturing was passed to Robin.
