Design and Demonstration for Area Walkway Lighting on Electric- powered, Mobile, Surface Mining Equipment.
The January 13, 1977, federal register (v. 42, No. 9, Sec. 77.027, Par. D) proposed new regulations specifically applicable to aboveground operations directly related to illumination of areas in, on, and around draglines, shovels, and wheel excavators. This report details the design, installation, and demonstration of lighting systems of large draglines and shovels for areas 20 ft in all directions from the main frame, exterior walkways on board the mining machines, and the area beneath the boom 20 ft from the main frame to the farthest point the equipment is capable of excavating or discharging materials.
