Latest Patents

One of Mickelson's latest patents is the "Multiple Speed Hoisting System with Pressure Protection and Load Control." This invention features a dual fluid circuit design that allows for the hoisting of heavy loads at low speed while accommodating lighter loads at higher speeds. The first fluid circuit maximizes effective cross-sectional area for heavy loads, whereas the second has a smaller effective cross-sectional area for lighter loads. A valve responsive to a regulating means selectively positions the circuits, while a pressure-controlled mechanism automatically cancels the influence of the regulating means upon reaching a predetermined pressure level, reverting to the first fluid circuit. This design minimizes undesirable oscillations within the system, enhancing stability and reliability.
