Title: Jack A Holt: Innovator in Concrete Hoisting Solutions

Introduction

Jack A Holt is a notable inventor based in Belmont, California, with a focus on innovative solutions for concrete hoisting. He holds a total of four patents that showcase his expertise in creating efficient and effective lifting systems for concrete slabs. His contributions to the field have significantly improved the safety and functionality of concrete handling.

Latest Patents

Among his latest patents, Holt has developed a "Hoisting Coupling for Concrete Slabs." This invention features a remotely releasable hoisting coupling designed for engagement with an anchor cast within a concrete slab. The coupling includes a body that can be inserted into the anchor, along with a pair of lugs that can rock about a diametric axis. These lugs can be selectively moved between a protruding condition, which engages with an abutment shoulder, and a retracted condition, allowing for disengagement. The design incorporates a lifting bail for pivotal movement, enhancing its usability.

Another significant patent is the "Lift System for Concrete Slabs." This invention involves a lifting anchor that is incorporated into a poured concrete slab. The anchor consists of a steel sleeve with an irregular exterior surface to ensure a strong bond with the concrete. It features an interior cylindrical opening that is initially sealed during the pouring process. After the slab is formed, the sleeve allows for access to its interior, where a hoisting coupling can be engaged. This system enables remote disengagement of the lugs from the abutment, providing convenience and safety during lifting operations.
