Latest Patents
One of McCormick's latest patents is a hoist apparatus that features a three-part double reeved bottom block, designed to maintain the same height profile and lifting capacity as a traditional three-part bottom block. This invention includes an integral equalizer sheave nest and a device that limits the rotation of a hoist drum beyond a desired position. Additionally, he developed a hybrid gearbox that can be adapted for use on various hoist apparatuses, allowing for multiple configurations. Another significant innovation is a self-lubricating load braking assembly, which incorporates lubrication inlet and outlet holes for efficient maintenance. Furthermore, McCormick's controller is designed to acquire operational data and generate outputs indicative of the remaining useful life of the hoist apparatus, enhancing reliability and safety.
Another notable patent is the lifting arrangement for overhead traveling cranes. This arrangement utilizes two single reeved drums that are reeved together to provide true vertical lift of a load. It allows for the equalization of full up and full down rope fleet angles through the use of axially staggered dual drums and/or a bottom block with two separate sheave nests. This innovative design aims to reduce the overall cost of cranes compared to traditional powerhouse crane designs.
