ANSI ECMA15: 2018 Spec for Cable-less (Wireless) Controls

This standard provides the minimum requirements and guidelines for cable-less controls of electric overhead traveling cranes. A cable-less control device as referenced in this standard uses radio frequency signals to control the movements and actions of said cranes for applications such as material handling. This standard is referenced in CMAA Specification #70, Specifications for Top Running & Gantry Type Multiple Girder Electric Overhead Traveling Cranes, and CMAA Specification #74, Specifications for Top Running & Under Running Single Girder Electric Traveling Cranes Utilizing Under Running Trolley Hoist. These specifications contain information and references specific to electric overhead traveling (EOT) cranes.
