Abstract: A chain hoist (10) having an improved chain guide (12) for a link chain (14). The chain guide (12) has a channel (36) with a cross-shaped cross section, through which the link chain (14) extends. An end surface (26) of the chain guide (12) extends away from a mouth opening (28) of the channel (36). The channel (36) establishes a through-passage direction (D) which widens in the direction of the end surface (26), and a protrusion (30) is formed on the end surface (26) around the mouth opening (28) of the channel (36).
