MSHA PROGRAM POLICY MANUAL VOLUME V inspector has reason to believe that any equipment, including off-track mining equipment, has been allowed to contact the trolley or trolley feeder wires, creating a short circuit, this Section should be cited. The following precautions are considered adequate for movement of equipment other than off-track mining equipment in track and trolley entries: 1. Maintenance of 12 inches vertical clearance between the equipment being moved and energized trolley or trolley feeder wires; or 2. Deenergization of the trolley and trolley feeder wire while equipment is being moved along track and trolley entries; or 3. Transportation of the equipment in a mine car or other vehicle having two sides with dimensions not greater than the sides of mine cars normally used in the track haulage system. The equipment being transported shall not extend above the sides of the mine car; or 4. Transportation of small items of mine equipment, such as small pumps, component parts of mining equipment, and mine supplies, in a vehicle that normally traverses the intended route, provided no part of the equipment being transported extends higher than that part of the frame of the vehicle that is in front of or to the rear of the item being transported. If items 1 through 4 cannot be met, adequate protection would require compliance with Sections 75.1003-2(a) through 75.1003- 2(f)(5) or other equally effective safeguards designed to insure that such equipment will not contact energized trolley wires or trolley feeder wires. 75.1003-2 Requirements for Movement of Off-Track Mining Equipment in Areas of Active Workings Where Energized Trolley Wires or Trolley Feeder Wires are Present; Premovement Requirements; Certified and Qualified Persons "Off-track mining equipment" for the purpose of this Section is interpreted to be a major item of complete or reasonably complete mining equipment, built on its own individual frame, consisting of its own components, performing its own unique function, and not designed to operate on mine track. "Off-track mining equipment" includes all self-propelled equipment February 2003 (Release V-33) 89
MSHA PROGRAM POLICY MANUAL VOLUME V including cat-mounted rubber-tired or skid-mounted equipment. "Off-track mining equipment" includes major items of complete or reasonably complete mobile or stationary mining equipment that is used in the production of coal or to supply electrical, hydraulic, or pneumatic power to mining equipment. At times, cutting heads, drill booms, conveyor booms, electric motors, etc., are removed from machines to facilitate transportation in the restricted confines of coal mine entries. These machines are still considered to be off-track mining equipment within the meaning of this Section. However, the detached cutting heads, drill booms, conveyor booms, electric motors, etc., are component parts of a machine and cannot be considered to be off-track mining equipment. Neither can roof bolts, oil barrels, steel ties, steel rails, belt structure, or other mine supplies be considered as off-track mining equipment. When the trolley wire and trolley feeder wire are 12 inches horizontally from the equipment being moved, the equipment almost always passes under turnouts where the trolley wire and trolley feeder wire will be directly over the equipment being moved. Therefore, 12 inches horizontal clearance is not acceptable as compliance with this Section. The measurement of 12 inches vertical clearance shall be determined by measuring vertically from the trolley wire to a perpendicular line intersecting with the highest projection on the equipment being moved.
