Document Type and Number:
Japanese Patent JP2790615
Kind Code:
B2
Abstract:
An elevator governor has two balancing springs, i.e., a first balancing spring for continually urging flyweights in a direction against a centrifugal force and a second balancing spring for urging flyweights in a direction against the centrifugal force only when speed of a cage exceeds a previously set first overspeed. Thereby, two overspeeds may be set independently from each other whereby the setting operation may be facilitated and accuracy in setting the overspeeds may be improved.
