Abstract

A lifting device comprises a lifting beam formed by two opposed members, for example I or U-section. Self-locking carriages are movable along the beam internally thereof and include lugs engageable with upper and lower flanges of the members. A shaft carried by each carriage is engaged by a beam suspension member or a load supporting hook, and the load applied to the carriage via the shaft urges the lugs into locking engagement with the flanges.
