The 8100 and 7500 levels are connected by a ramp. Disabled vehicles on the 7500 level are towed to the 8100 level or raised to the surface facilities, which are connected to both levels by a vertical shalt and cage. Using the cage to move equipment regDires partial dismantling of larger mobile units. Maintenance work is divided among the three facili- ties as follows: ^ Mobile equipment is inspected, lubricated, and serviced wherever the unit operates. ^ Major equipment components are replaced in the unit at the 8100 level shop-where most underground bayspace, tools, eyuipment, and maintenance personnel are located. ^ Major overhauls are dune at the surface: shop, after stripping and cleaning a unit underground. Organizing aplanning-scheduling stailf The Henderson operation employs 250 people in main- tenance work. The staff assigned to planning, schedul- ing, and collecting data for maintenance of mobile eyuipment includes: ^ A maintenance planner, who plans and administers scheduled maintenance. He analyzes the work load, assigns labor, eyuipment, materials, and bayspace to accomplish each job, and schedules the time during which the equipment is available fur maintetance. ^ A material controller, who assists the planner in making sure that material, parts, and fabrications will be available to meet the scheduled work. ^ A tire-program coordinator, who supervises the procedures for use and preventive mainterance of all tires, including repair, recapping, and replacement. Good control is absolutely necessary to avoid excessive tire costs-a major operating expense.
