Each end of the sheave shaft extends beyond a side of the boom point and rotatably mounts a sheave. A torque rod having one end anchored to the boom point and its other end fixed to the sheave shaft exerts a restoring torque on the sheave shaft should the sheave shaft pivot away from its normal horizontal position.
