ABSTRACT:
A hand-operated chain block having a hand chain wheel portion light in weight and simplified in construction and which permits safe and smooth hand chain operation. A hand chain wheel cover is mounted on a plurality of stays disposed on side plates of a chain block body in such a manner as to cover the upper, lower and front portions of the hand chain wheel, and a pair of hand chain guide plates are mounted on an upper pair of stays to cover the side portions of the hand chain wheel, thereby covering substantially the entire periphery of the hand chain wheel. Each of the hand chain guide plates is formed of one metal plate in a folded pattern, and the pivotal support portion at its upper end part is inserted into the upper stay, and the hand chain guide plate is oscillatably suspended and supported, while a hand chain wound around the hand chain wheel is inserted through a hand chain guide portion formed at the lower end portion so as to be guided. A guide plate fixing member is detachably fitted to a lower stay to simultaneously fix the lower end portion of each of the hand chain guide plate.
