134. For an electro-hydraulic cargo-handling pedestal-type deck crane, what event would result in an immediate stop to all crane motions, including slewing, hoisting, and luffing?
Loss of electric power immediately stops all crane motions by disabling the electric motor that drives the hydraulic pumps, eliminating power to slewing, hoisting, and luffing functions.
