Enhanced deployment of safety cage apparatus for tanks on vehicles

摘要

A cage for surrounding a section of a work area of the top of rolling stock forms part of a portable fall protection device that includes a positioning mechanism capable of telescoping, folding and pivoting motions that are maneuvered by pneumatically-powered or hydraulically-powered apparatus. A gate, lock, pressure lines, valves and control devices are combined with the cage to ensure proper deployment of worker fall protection in this working environment.
