ABSTRACT:
A hand operated chain block which is capable of fixing an end of a load chain of unloading side and also ensuring smooth wind up and down operation of the load chain, while reducing the size of chain block. In the hand operated chain block, the fixing pin is located at a position in a marginal portion around each side plate such that an interval between a chain split and a rotation trail of a tip of an end portion on the loading side of the first link of the load chain rotatably supported by the fixing pin can be made larger than a width of a link of the load chain, and also that when a full length of the load chain of loading side is wound down, an end portion on the loading side of the second link next to the first link can abut with the end portion on the unloading side of the chain guide.
