 An initial conveyor run of about or 213 meters carried the mix from the plant up the hill to a transfer station; from there, a second conveyor transported the mix along the top of the dam to a "tripper".The tripper, which could be positioned along the second conveyor's run, diverted the RCC from the distribution conveyor and discharged it onto the working surface at the desired location.As the RCC was discharged by the tripper, it was spread in 12-inch (30 cm) lifts by a bulldozer.
