The company was originally established in 1952 as Del Mar Engineering Laboratories by Bruce Del Mar, who led the development of aircraft cabin pressurization systems, helping make possible today`s commercial aircraft industry.

Since 1965, thousands of Hydra Set Precision Load Positioners have been utilized in a wide range of industries and rugged environments worldwide.

Installed between the crane (or hoist) and the load, Hydra Set is a valuable positioning device that enables the operator to mate and de-mate loads from Â½ ton (453.6 kg) to 300 tons (272,000 kg) to within 0.001 inch (0.025mm).

In 1965, the company introduced the Hydra Set Load Positioner that controls the precise vertical positioning of loads up to 300 tons (272,000 kg) in increments as small as 0.001 inch (0.025mm). This unique product, mounted between the load and the crane (or hoist), permits precise mating and de-mating of critical components, thus eliminating unforeseen damage to valuable loads. Thousands of Hydra Set Load Positioners are in use worldwide in the aerospace, military/commercial aviation, nuclear and fossil fuel power generating industries and in various industrial applications.
