Abstract

An equalizing rigging block for use with a synthetic roundsling is disclosed. The rigging block includes in preferred embodiments (a) a flatter and wider sheave to better accommodate a wider or flatter cross-section synthetic roundsling; (b) higher side sections for the sheave; and (c) a plurality of stacked bearings along the rigging block axis to provide enhanced lateral stability of the rigging block. In preferred embodiments, the rigging block sheave is manufactured from a synthetic material, such as plastic. The equalizing rigging block exhibits improved characteristics of holding a synthetic roundsling within the rigging block, and of reducing wear and tear on the roundsling.
