Overview of Electric Overhead Traveling (EOT) Cranes
Course Highlights

This online engineering PDH course presents an overview of electric overhead traveling cranes, discusses the mechanical aspects of the appropriate selection, and includes civil, structural and electric design parameters.

 

A crane is a machine that lifts, lowers and moves load horizontally. By construction, cranes are divided into the overhead and gantry cranes. An overhead crane, also known as a bridge crane, is a type of crane where the hook and line mechanism run along a horizontal beam that travels on two widely separated rails. Often, it is in a factory building and runs along rails mounted on two long walls. A gantry crane is similar to an overhead crane, except that the bridge carrying the trolley is rigidly supported on two or more legs moving on fixed rails embedded in the floor.

 

Overhead traveling cranes are also available in various configurations. The two main categorizations are top-running versus under-running bridge cranes and single-girder versus double-girder bridge cranes. A crane travel is directed by an operator, either manually or with a wired pendant station or wireless controls that guide their electric- or pneumatic-powered travel. Typical uses include multi-directional movement of materials through the production process, support manufacturing, transporting heavy items to and from storage areas, and loading or unloading activities inside a warehouse or onto open trailers or railcars.

 

This 6 PDH online course is applicable to mechanical engineers, electrical engineers, structural engineers, construction engineers, factory and workshop operators, supervisors, O&M professionals, facility managers, estimators and general audience seeking to gain a better understanding of electric overhead traveling cranes. No specific prerequisite training or experience is required.
