Abstract

PURPOSE: To increase frictional force between a rope groove and a rope by putting frictional force gaining material in a concave which is formed under a rope-wound- groove.
CONSTITUTION: Frictional force gaining material 10 such as asbestos, high in coefficient of friction, is put in an undercut groove 5b of a sheave 5 under which elastic material 11 is put in the meterial 10 to fix on the undercut groove 5b. As the elastic material 10 functions to press the frictional force gaining material 10 between the lower face of a rope concurrently, the ceofficient of friction can gain greatly due to attachment of detritus on the surface of the rope 7. If wore, the frictional gaining material 10 kept on the elastic material 11 is raised up to make up so that it can be used for prolonged period.
