Patent

CA 2236731

A hand operated chain block is disclosed which is capable of fixing an end of a load chain of an 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 a space 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 a 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 of the unloading side of the chain guide.
