  • Mechanical safety fuse link
    Publication number: 20030200819
    Abstract: A safety fuse link, usable as a serial element of a load lifting line, has a telescoping body held in a short configuration by a linear slip clutch or a shear pin until a selected load on the line is exceeded. The body then extends to a longer configuration in which it is retained as a length unit by abutting surfaces between which an blastomeric shock cushion is positioned. An optional arrangement includes a biasing arrangement to restore the link to the original condition for further use, after the load is reduced.
