ABSTRACT:
A pulley comprises a pair of flanges, a rotary roller mounted on a first spindle, and a second flange which oscillates on the first spindle. A jammer is incorporated inside the pulley and comprises a pivotable tumbler on a second spindle between an active locking position and an inactive unlocking position of a rope. The second spindle is tubular and extends parallel to the first spindle, and includes an internal orifice disposed to come into alignment with a hole of the second flange when the second flange reaches a position near to a closed position, so as to enable a snap-hook to be attached through an orifice of the tumbler simultaneously resulting in locking of the second flange in the closed position.
