A chain drive for chain hoist with two link chains including two chain wheels arranged adjacent on a shaft and in torque-proof connection to one another, each chain wheel being used to guide a section of link chain having alternately horizontal and vertical links, namely, with pockets for accommodating horizontal links and with a groove extending in the circumferential direction for accommodating vertical links. The chain wheels have a fixed angular offset smaller than the angular pitch between two successive chain links of a chain wheel. This chain drive forms a chain drive system together with a sling for two link chains running parallel, wherein the sling includes, at one end, a connecting part for a load and, opposite thereto, two adjacently arranged connection portions for respective end links of either link chain, wherein the connection portions are offset from one another along the load direction with a linear offset smaller than the chain pitch along the load direction.
