The Hale Copper Mine is located near Indiahoma, Oklahoma, within the Oreana Mining District, which is now part of the Wichita Mountains Wilderness. The site was initially discovered in 1884 by James Hale and his wife Bessie. Although the Hale Copper Mine is currently closed with no known plans for reopening, it operated from 1887 to 1960.
The loading chutes were pivotal in the transportation of copper ore pulled up from the mine shaft. During operation it would be common to see rail cars loading ore and moving it along. Massive Loading chutes on both the right and left of this picture so that two rail cars could come underneath at the same time to collect ore.
Assembly conditions for systems located in the open sea always present a special challenge. For this project, pre-assembled large components were transported and installed using self-loading and unloading heavy-lift ships. For this purpose, two deck cranes with a load capacity of 1,000 tons each, installed on a vessel, came to use.
