Title: Innovations by Eric Holloway in Railroad Structure Lifting

Introduction

Eric Holloway is an accomplished inventor based in Boise, ID, known for his innovative contributions to the field of railroad structure lifting. With a total of two patents to his name, Holloway has developed methods and apparatuses that enhance the efficiency and safety of railroad maintenance.

Latest Patents

Holloway's latest patents include a method, apparatus, and system for lifting railroad structures. This system is designed to raise the height of railroad structures, which are defined as the areas where two or more railway tracks merge, cross, or divide. The method involves excavating an opening beneath a railway track at or adjacent to a railroad structure. Hydraulic jacks are strategically positioned within the opening, and this process is repeated until enough jacks are in place around the structure. Once positioned, the hydraulic jacks are actuated to raise the railroad structure to a desired height, typically providing a slight crown to the structure. After raising, ballast is positioned beneath the elevated railway. The hydraulic jacks can either be disconnected from the hydraulic lines and left in place or removed for future use. For improved transportability, the hydraulic jacks are preferably positioned on sleds that facilitate easy movement and provide a stable platform for operation.

Another significant patent by Holloway is a jacking tie and method for leveling and lifting railroad tracks. This jacking tie features an elongate body designed to span beneath two parallel rails of a railroad track. It is configured to replace a standard railroad tie and includes two hydraulic cylinder jacks that lift each of the parallel rails. The jacking tie body consists of two sections, with a track support shell that is supported by the hydraulic jacks. This innovative design allows for the independent raising of the ends of the track support shell, enabling efficient lifting and lowering of the railroad track while maintaining operational integrity.
