Mina Copper opens load cards, bell signals and the outgoing operator’s handoff slate at the cargo lift at Three Roots Junction. Before anyone changes a mark, the crew checks the upper bell can be heard at the lower landing only when the tool screen is closed. The vent change period sets the pace of the work.
The page holds 65 loads with a confirmed signal at both landings. Mina Copper reads the preceding count, 66, before the next line is entered. A number without a date would not tell the next crew what changed.
Operators rely on the signal at their own landing. Loaders ask for a shared confirmation before the lift moves. Here the difference is visible between the posted rule and the route, service or shift just beyond the door.
The board publishes two route options with access and repair limits stated. The Year third, vent change window 3 file remains open for its scheduled decision. The lift board will test a two-landing signal before the next heavy load.
The shift closes with the source page attached to the board. The next file uses a new date and scope.
