Load transfer detection device for fail-safe jackscrew, has verification unit verifying, without rupture of slug, operation of slug rupture detection unit that comprise sensors and monitoring device

摘要

The device has a verification unit verifying, without rupture of a slug (1), the operation of a slug rupture detection unit. The detection unit has sensors (14, 15) with each disposed respectively on an upper plate (7) and a lower plate (12) of the slug. The detection unit has a monitoring device (16) to determine whether spacing between the sensors is normal or irregular. An independent claim is also included for a movable unit activating jackscrew.
